Command-Line Reference

bazel [<startup options>] <command> [<args>]

bazel [<startup options>] <command> [<args>] -- [<target patterns>]

See the User's Guide for the target patterns syntax.

Option Syntax

Options can be passed to Bazel in different ways. Options that require a value can be passed with either an equals sign or a space:

--<option>=<value>
--<option> <value>

Some options have a single character short form; in that case, the short form has to be passed with a single dash and a space.

-<short_form> <value>

Boolean options can be enabled as follows:

--<option>
--<option>=[true|yes|1]

and disabled as follows:

--no<option>
--<option>=[false|no|0]

Tristate options are usually set to automatic by default, and can be force-enabled as follows:

--<option>=[true|yes|1]

or force-disabled as follows:

--no<option>
--<option>=[false|no|0]

Startup Options

--[no]batch default: "false": If set, Bazel will be run as just a client process without a server, instead of in the standard client/server mode. This is deprecated and will be removed, please prefer shutting down the server explicitly if you wish to avoid lingering servers.
Tags: loses_incremental_state, bazel_internal_configuration, deprecated
--[no]batch_cpu_scheduling default: "false": Only on Linux; use 'batch' CPU scheduling for Bazel. This policy is useful for workloads that are non-interactive, but do not want to lower their nice value. See 'man 2 sched_setscheduler'. If false, then Bazel does not perform a system call.
Tags: host_machine_resource_optimizations
--bazelrc=<path> default: see description: The location of the user .bazelrc file containing default values of Bazel options. If unspecified, Bazel uses the first .bazelrc file it finds in the following two locations: the workspace directory, then the user's home directory. Use /dev/null to disable the search for a user rc file, e.g. in release builds.
Tags: changes_inputs
--[no]block_for_lock default: "true": When --noblock_for_lock is passed, Bazel does not wait for a running command to complete, but instead exits immediately.
Tags: eagerness_to_exit
--[no]client_debug default: "false": If true, log debug information from the client to stderr. Changing this option will not cause the server to restart.
Tags: affects_outputs, bazel_monitoring
--connect_timeout_secs=<an integer> default: "30": The amount of time the client waits for each attempt to connect to the server
Tags: bazel_internal_configuration
--[no]deep_execroot default: "true": If set, the execution root will be under $OUTPUT_BASE/execroot instead of $OUTPUT_BASE.
Tags: loses_incremental_state, execution
--[no]expand_configs_in_place default: "true": Changed the expansion of --config flags to be done in-place, as opposed to in a fixed point expansion between normal rc options and command-line specified options.
Tags: no_op, deprecated
--[no]home_rc default: "true": Whether or not to look for the home bazelrc file at $HOME/.bazelrc
Tags: changes_inputs
--[no]idle_server_tasks default: "true": Run System.gc() when the server is idle
Tags: loses_incremental_state, host_machine_resource_optimizations
--[no]ignore_all_rc_files default: "false": Disables all rc files, regardless of the values of other rc-modifying flags, even if these flags come later in the list of startup options.
Tags: changes_inputs
--io_nice_level={-1,0,1,2,3,4,5,6,7} default: "-1": Only on Linux; set a level from 0-7 for best-effort IO scheduling using the sys_ioprio_set system call. 0 is highest priority, 7 is lowest. The anticipatory scheduler may only honor up to priority 4. If set to a negative value, then Bazel does not perform a system call.
Tags: host_machine_resource_optimizations
--macos_qos_class=<a string> default: "default": Sets the QoS service class of the bazel server when running on macOS. This flag has no effect on all other platforms but is supported to ensure rc files can be shared among them without changes. Possible values are: user- interactive, user-initiated, default, utility, and background.
Tags: host_machine_resource_optimizations
--max_idle_secs=<integer> default: "10800": The number of seconds the build server will wait idling before shutting down. Zero means that the server will never shutdown.
Tags: eagerness_to_exit, loses_incremental_state
--output_base=<path> default: see description: If set, specifies the output location to which all build output will be written. Otherwise, the location will be ${OUTPUT_ROOT}/_bazel_${USER} /${MD5_OF_WORKSPACE_ROOT}. Note: If you specify a different option from one to the next Bazel invocation for this value, you'll likely start up a new, additional Bazel server. Bazel starts exactly one server per specified output base. Typically there is one output base per workspace - however, with this option you may have multiple output bases per workspace and thereby run multiple builds for the same client on the same machine concurrently. See ' bazel help shutdown' on how to shutdown a Bazel server.
Tags: affects_outputs, loses_incremental_state
--output_user_root=<path> default: see description: The user-specific directory beneath which all build outputs are written; by default, this is a function of $USER, but by specifying a constant, build outputs can be shared between collaborating users.
Tags: affects_outputs, loses_incremental_state
--server_jvm_out=<path> default: see description: The location to write the server's JVM's output. If unset then defaults to a location in output_base.
Tags: affects_outputs, loses_incremental_state
--[no]shutdown_on_low_sys_mem default: "false": If max_idle_secs is set and the build server has been idle for a while, shut down the server when the system is low on free RAM. Linux only.
Tags: eagerness_to_exit, loses_incremental_state
--[no]system_rc default: "true": Whether or not to look for the system-wide bazelrc.
Tags: changes_inputs
--[no]unlimit_coredumps default: "false": Raises the soft coredump limit to the hard limit to make coredumps of the server (including the JVM) and the client possible under common conditions. Stick this flag in your bazelrc once and forget about it so that you get coredumps when you actually encounter a condition that triggers them.
Tags: bazel_internal_configuration
--[no]watchfs default: "false": If true, bazel tries to use the operating system's file watch service for local changes instead of scanning every file for a change.
Tags: deprecated
--[no]workspace_rc default: "true": Whether or not to look for the workspace bazelrc file at $workspace/.bazelrc
Tags: changes_inputs

--[no]incompatible_enable_execution_transition default: "false": If false, the execution transition behaves like the host transition.
Tags: bazel_internal_configuration, incompatible_change, triggered_by_all_incompatible_changes

--host_jvm_args=<jvm_arg> multiple uses are accumulated: Flags to pass to the JVM executing Bazel.
--host_jvm_debug: Convenience option to add some additional JVM startup flags, which cause the JVM to wait during startup until you connect from a JDWP-compliant debugger (like Eclipse) to port 5005.
Expands to:
--host_jvm_args=-Xdebug
--host_jvm_args=-Xrunjdwp:transport=dt_socket,server=y,address=5005
--host_jvm_profile=<profiler_name> default: "": Convenience option to add some profiler/debugger-specific JVM startup flags. Bazel has a list of known values that it maps to hard-coded JVM startup flags, possibly searching some hardcoded paths for certain files.
--server_javabase=<jvm path> default: "": Path to the JVM used to execute Bazel itself.

Options Common to all Commands

--experimental_oom_more_eagerly_threshold=<an integer> default: "100": If this flag is set to a value less than 100, Bazel will OOM if, after two full GC's, more than this percentage of the (old gen) heap is still occupied.
Tags: host_machine_resource_optimizations

--[no]debug_depset_depth default: "false": Enables an expensive additional check that causes depset construction to fail fast if the depset's depth would exceed the limit specified by `-- nested_set_depth_limit`. Ordinarily this failure occurs only when the depset is flattened, which may be far from its point of creation.
Tags: build_file_semantics

--build_metadata=<a 'name=value' assignment> multiple uses are accumulated: Custom key-value string pairs to supply in a build event.
Tags: terminal_output
--color=<yes, no or auto> default: "auto": Use terminal controls to colorize output.
--config=<a string> multiple uses are accumulated: Selects additional config sections from the rc files; for every < command>, it also pulls in the options from <command>:<config> if such a section exists; if this section doesn't exist in any .rc file, Bazel fails with an error. The config sections and flag combinations they are equivalent to are located in the tools/*.bazelrc config files.
--curses=<yes, no or auto> default: "auto": Use terminal cursor controls to minimize scrolling output.
--[no]enable_platform_specific_config default: "false": If true, Bazel picks up host-OS-specific config lines from bazelrc files. For example, if the host OS is Linux and you run bazel build, Bazel picks up lines starting with build:linux. Supported OS identifiers are linux, macos, windows, freebsd, and openbsd. Enabling this flag is equivalent to using --config=linux on Linux, --config=windows on Windows, etc.
--[no]experimental_multi_threaded_digest default: "true": Whether to always compute digests of files with multiple threads. Setting this to false may improve performance when using a spinning platter.
--experimental_ui_limit_console_output=<an integer> default: "0": Number of bytes to which the UI will limit its output (non-positive values indicate unlimited). Once the limit is approaching, the UI will try hard to limit in a meaningful way, but will ultimately just drop all output.
--experimental_ui_mode=<oldest_actions or mnemonic_histogram> default: "oldest_actions": Determines what kind of data is shown in the detailed progress bar. By default, it is set to show the oldest actions and their running time. The underlying data source is usually sampled in a mode-dependend way to fit within the number of lines given by --ui_actions_shown.

--aspect_deps=<off, conservative or precise> default: "conservative": How to resolve aspect dependencies when the output format is one of {xml,proto, record}. 'off' means no aspect dependencies are resolved, ' conservative' (the default) means all declared aspect dependencies are added regardless of whether they are given the rule class of direct dependencies, 'precise' means that only those aspects are added that are possibly active given the rule class of the direct dependencies. Note that precise mode requires loading other packages to evaluate a single target thus making it slower than the other modes. Also note that even precise mode is not completely precise: the decision whether to compute an aspect is decided in the analysis phase, which is not run during 'bazel query'.
Tags: build_file_semantics
--[no]implicit_deps default: "true": If enabled, implicit dependencies will be included in the dependency graph over which the query operates. An implicit dependency is one that is not explicitly specified in the BUILD file but added by bazel.
Tags: build_file_semantics
--[no]include_artifacts default: "true": Includes names of the action inputs and outputs in the output (potentially large).
Tags: terminal_output
--[no]include_aspects default: "false": Whether to include aspect generated actions in the output.
Tags: terminal_output
--[no]include_commandline default: "true": Includes the content of the action command lines in the output (potentially large).
Tags: terminal_output
--[no]include_param_files default: "false": Include the content of the param files used in the command (potentially large). Note: Enabling this flag will automatically enable the --include_commandline flag.
Tags: terminal_output
--[no]incompatible_proto_output_v2 default: "false": Whether aquery should print proto/textproto results with proto v2 (with ids in uint64 instead of string).
Tags: terminal_output, incompatible_change, triggered_by_all_incompatible_changes
--[no]nodep_deps default: "true": If enabled, deps from "nodep" attributes will be included in the dependency graph over which the query operates. A common example of a " nodep" attribute is "visibility". Run and parse the output of `info build-language` to learn about all the "nodep" attributes in the build language.
Tags: build_file_semantics
--output=<a string> default: "text": The format in which the aquery results should be printed. Allowed values for aquery are: text, textproto, proto, jsonproto.

Tags: build_file_semantics
--[no]proto:include_synthetic_attribute_hash default: "false": Whether or not to calculate and populate the $internal_attr_hash attribute.
Tags: terminal_output
--[no]proto:locations default: "true": Whether to output location information in proto output at all.
Tags: terminal_output
--proto:output_rule_attrs=<comma-separated list of options> default: "all": Comma separated list of attributes to include in output. Defaults to all attributes. Set to empty string to not output any attribute. This option is applicable to --output=proto.

Tags: terminal_output
--[no]skyframe_state default: "false": Without performing extra analysis, dump the current Action Graph from Skyframe. Note: Specifying a target with --skyframe_state is currently not supported. This flag is only available with --output=proto or --output=textproto.
Tags: terminal_output
--[no]tool_deps default: "true": Query: If disabled, dependencies on 'host configuration' or ' execution' targets will not be included in the dependency graph over which the query operates. A 'host configuration' dependency edge, such as the one from any 'proto_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same ' target' program. Cquery: If disabled, filters out all configured targets which cross a host or execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the host configuration, only host configured targets will be returned.
Tags: build_file_semantics
--universe_scope=<comma-separated list of options> default: "": A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands. For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

--[no]experimental_remotable_source_manifests default: "false": Whether to make source manifest actions remotable
Tags: loading_and_analysis, execution, experimental
--[no]experimental_strict_fileset_output default: "false": If this option is enabled, filesets will treat all output artifacts as regular files. They will not traverse directories or be sensitive to symlinks.
Tags: execution
--modify_execution_info=<regex=[+-]key,regex=[+-]key,...> default: "": Add or remove keys from an action's execution info based on action mnemonic. Applies only to actions which support execution info. Many common actions support execution info, e.g. Genrule, CppCompile, Javac, SkylarkAction, TestRunner. When specifying multiple values, order matters because many regexes may apply to the same mnemonic. Syntax: "regex=[+-]key,[+-]key,...". Examples: '.*=+x,.*=-y,.*=+z' adds 'x' and 'z' to, and removes 'y' from, the execution info for all actions. 'Genrule=+requires-x' adds 'requires-x' to the execution info for all Genrule actions. '(?!Genrule).*=-requires-x' removes 'requires-x' from the execution info for all non-Genrule actions.

--[no]proto:include_synthetic_attribute_hash default: "false": Whether or not to calculate and populate the $internal_attr_hash attribute.
Tags: terminal_output
--[no]proto:locations default: "true": Whether to output location information in proto output at all.
Tags: terminal_output
--proto:output_rule_attrs=<comma-separated list of options> default: "all": Comma separated list of attributes to include in output. Defaults to all attributes. Set to empty string to not output any attribute. This option is applicable to --output=proto.
Tags: terminal_output
--[no]proto:rule_inputs_and_outputs default: "true": Whether or not to populate the rule_input and rule_output fields.
Tags: terminal_output
--[no]relative_locations default: "false": If true, the location of BUILD files in xml and proto outputs will be relative. By default, the location output is an absolute path and will not be consistent across machines. You can set this option to true to have a consistent result across machines.
Tags: terminal_output
--[no]skyframe_state default: "false": Without performing extra analysis, dump the current Action Graph from Skyframe. Note: Specifying a target with --skyframe_state is currently not supported. This flag is only available with --output=proto or --output=textproto.
Tags: terminal_output
--[no]tool_deps default: "true": Query: If disabled, dependencies on 'host configuration' or ' execution' targets will not be included in the dependency graph over which the query operates. A 'host configuration' dependency edge, such as the one from any 'proto_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same ' target' program. Cquery: If disabled, filters out all configured targets which cross a host or execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the host configuration, only host configured targets will be returned.
Tags: build_file_semantics
--universe_scope=<comma-separated list of options> default: "": A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands. For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

--[no]collapse_duplicate_defines default: "false": When enabled, redundant --defines will be removed early in the build. This avoids unnecessary loss of the analysis cache for certain types of equivalent builds.
Tags: loading_and_analysis, loses_incremental_state
--[no]distinct_host_configuration default: "true": Build all the tools used during the build for a distinct configuration from that used for the target program. When this is disabled, the same configuration is used for host and target programs. This may cause undesirable rebuilds of tools such as the protocol compiler (and then everything downstream) whenever a minor change is made to the target configuration, such as setting the linker options. When this is enabled (the default), a distinct configuration will be used to build the tools, preventing undesired rebuilds. However, certain libraries will then need to be compiled twice, once for each configuration, which may cause some builds to be slower. As a rule of thumb, this option is likely to benefit users that make frequent changes in configuration (e.g. opt/dbg). Please read the user manual for the full explanation.

--[no]incompatible_default_to_explicit_init_py default: "false": This flag changes the default behavior so that __init__.py files are no longer automatically created in the runfiles of Python targets. Precisely, when a py_binary or py_test target has legacy_create_init set to "auto" (the default), it is treated as false if and only if this flag is set. See https: //github.com/bazelbuild/bazel/issues/10076.
Tags: affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_py2_outputs_are_suffixed default: "true": If true, targets built in the Python 2 configuration will appear under an output root that includes the suffix '-py2', while targets built for Python 3 will appear in a root with no Python-related suffix. This means that the `bazel-bin` convenience symlink will point to Python 3 targets rather than Python 2. If you enable this option it is also recommended to enable `-- incompatible_py3_is_default`.
Tags: affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_py3_is_default default: "true": If true, `py_binary` and `py_test` targets that do not set their `python_version` (or `default_python_version`) attribute will default to PY3 rather than to PY2. If you set this flag it is also recommended to set `-- incompatible_py2_outputs_are_suffixed`.

--[no]incompatible_use_python_toolchains default: "true": If set to true, executable native Python rules will use the Python runtime specified by the Python toolchain, rather than the runtime given by legacy flags like --python_top.
Tags: loading_and_analysis, incompatible_change, triggered_by_all_incompatible_changes
--python_version=<PY2 or PY3> default: see description: The Python major version mode, either `PY2` or `PY3`. Note that this is overridden by `py_binary` and `py_test` targets (even if they don't explicitly specify a version) so there is usually not much reason to supply this flag.
Tags: loading_and_analysis, affects_outputs

--[no]cache_test_results [-t] default: "auto": If set to 'auto', Bazel reruns a test if and only if: (1) Bazel detects changes in the test or its dependencies, (2) the test is marked as external, (3) multiple test runs were requested with --runs_per_test, or(4) the test previously failed. If set to 'yes', Bazel caches all test results except for tests marked as external. If set to 'no', Bazel does not cache any test results.
--check_constraint=<a string> multiple uses are accumulated: Check the listed constraint.
--[no]experimental_cancel_concurrent_tests default: "false": If true, then Bazel will cancel concurrently running tests on the first successful run. This is only useful in combination with -- runs_per_test_detects_flakes.

--[no]runs_per_test_detects_flakes default: "false": If true, any shard in which at least one run/attempt passes and at least one run/attempt fails gets a FLAKY status.
--shell_executable=<a path> default: see description: Absolute path to the shell executable for Bazel to use. If this is unset, but the BAZEL_SH environment variable is set on the first Bazel invocation (that starts up a Bazel server), Bazel uses that. If neither is set, Bazel uses a hard-coded default path depending on the operating system it runs on (Windows: c:/tools/msys64/usr/bin/bash.exe, FreeBSD: /usr/local/bin/bash, all others: /bin/bash). Note that using a shell that is not compatible with bash may lead to build failures or runtime failures of the generated binaries.
Tags: loading_and_analysis

Tags: bazel_internal_configuration
--[no]experimental_repository_cache_hardlinks default: "false": If set, the repository cache will hardlink the file in case of a cache hit, rather than copying. This is inteded to save disk space.
Tags: bazel_internal_configuration
--experimental_scale_timeouts=<a double> default: "1.0": Scale all timeouts in Starlark repository rules by this factor. In this way, external repositories can be made working on machines that are slower than the rule author expected, without changing the source code

Tags: bazel_internal_configuration

--[no]experimental_delay_virtual_input_materialization default: "false": If set to true, creates virtual inputs (like params files) only inside the sandbox, not in the execroot, which fixes a race condition when using the dynamic scheduler. This flag exists purely to support rolling this bug fix out.
Tags: execution
--experimental_docker_image=<a string> default: "": Specify a Docker image name (e.g. "ubuntu:latest") that should be used to execute a sandboxed action when using the docker strategy and the action itself doesn't already have a container-image attribute in its remote_execution_properties in the platform description. The value of this flag is passed verbatim to 'docker run', so it supports the same syntax and mechanisms as Docker itself.
Tags: execution
--[no]experimental_docker_privileged default: "false": If enabled, Bazel will pass the --privileged flag to 'docker run' when running actions. This might be required by your build, but it might also result in reduced hermeticity.
Tags: execution
--[no]experimental_docker_use_customized_images default: "true": If enabled, injects the uid and gid of the current user into the Docker image before using it. This is required if your build / tests depend on the user having a name and home directory inside the container. This is on by default, but you can disable it in case the automatic image customization feature doesn't work in your case or you know that you don't need it.
Tags: execution
--[no]experimental_docker_verbose default: "false": If enabled, Bazel will print more verbose messages about the Docker sandbox strategy.

--experimental_sandbox_async_tree_delete_idle_threads=<an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]<float>) eg. "auto", "HOST_CPUS*.5"> default: "0": If 0, delete sandbox trees as soon as an action completes (causing completion of the action to be delayed). If greater than zero, execute the deletion of such threes on an asynchronous thread pool that has size 1 when the build is running and grows to the size specified by this flag when the server is idle.
Tags: execution
--[no]experimental_sandboxfs_map_symlink_targets default: "false": If true, maps the targets of symbolic links specified as action inputs into the sandbox. This feature exists purely to workaround buggy rules that do not do this on their own and should be removed once all such rules are fixed.
--experimental_sandboxfs_path=<a string> default: "sandboxfs": Path to the sandboxfs binary to use when --experimental_use_sandboxfs is true. If a bare name, use the first binary of that name found in the PATH.
--[no]experimental_split_xml_generation default: "true": If this flag is set, and a test action does not generate a test.xml file, then Bazel uses a separate action to generate a dummy test.xml file containing the test log. Otherwise, Bazel generates a test.xml as part of the test action.
Tags: execution
--[no]experimental_use_sandboxfs default: "false": Use sandboxfs to create the actions' execroot directories instead of building a symlink tree. If "yes", the binary provided by -- experimental_sandboxfs_path must be valid and correspond to a supported version of sandboxfs. If "auto", the binary may be missing or not compatible.
--[no]experimental_use_windows_sandbox default: "false": Use Windows sandbox to run actions. If "yes", the binary provided by --experimental_windows_sandbox_path must be valid and correspond to a supported version of sandboxfs. If "auto", the binary may be missing or not compatible.
--experimental_windows_sandbox_path=<a string> default: "BazelSandbox.exe": Path to the Windows sandbox binary to use when -- experimental_use_windows_sandbox is true. If a bare name, use the first binary of that name found in the PATH.
--[no]incompatible_remote_symlinks default: "true": If set to true, Bazel will represent symlinks in action outputs in the remote caching/execution protocol as such. The current behavior is for remote caches/executors to follow symlinks and represent them as files. See #6631 for details.

--[no]incompatible_remove_local_resources default: "true": Deprecate local_resources in favor of --local_ram_resources and -- local_cpu_resources.
Tags: execution, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_symlinked_sandbox_expands_tree_artifacts_in_runfiles_tree default: "true": If enabled, the sandbox will expand tree artifacts in runfiles, thus the files that are contained in the tree artifact will be symlinked as individual files.
Tags: execution, triggered_by_all_incompatible_changes, incompatible_change
--jobs=<an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]<float>) eg. "auto", "HOST_CPUS*.5"> [-j] default: "auto": The number of concurrent jobs to run. Takes {@value FLAG_SYNTAX}. Values must be between 1 and5000 values above 2500 may cause memory issues. " auto" calculates a reasonable default based on host resources.
Tags: host_machine_resource_optimizations, execution
--[no]keep_going [-k] default: "false": Continue as much as possible after an error. While the target that failed and those that depend on it cannot be analyzed, other prerequisites of these targets can be.

Tags: execution, affects_outputs
--output_groups=<comma-separated list of options> multiple uses are accumulated: Specifies which output groups of the top-level targets to build. If omitted, a default set of output groups are built.

Tags: execution, affects_outputs

--aspects=<comma-separated list of options> multiple uses are accumulated: Comma-separated list of aspects to be applied to top-level targets. All aspects are applied to all top-level targets independently. Aspects are specified in the form <bzl-file-label>%<aspect_name>, for example '//tools: my_def.bzl%my_aspect', where 'my_aspect' is a top-level value from from a file tools/my_def.bzl
--[no]experimental_convenience_symlinks default: "normal": This flag controls how the convenience symlinks (the symlinks that appear in the workspace after the build) will be managed. Possible values: normal (default): Each kind of convenience symlink will be created or deleted, as determined by the build. clean: All symlinks will be unconditionally deleted. ignore: Symlinks will be left alone. log_only: Generate log messages as if 'normal' were passed, but don't actually perform any filesystem operations (useful for tools). Note that only symlinks whose names are generated by the current value of -- symlink_prefix can be affected; if the prefix changes, any pre-existing symlinks will be left alone.
Tags: affects_outputs
--[no]experimental_convenience_symlinks_bep_event default: "false": This flag controls whether or not we will post the build eventConvenienceSymlinksIdentified to the BuildEventProtocol. If the value is true, the BuildEventProtocol will have an entry for convenienceSymlinksIdentified, listing all of the convenience symlinks created in your workspace. If false, then the convenienceSymlinksIdentified entry in the BuildEventProtocol will be empty.

--remote_download_minimal: Does not download any remote build outputs to the local machine. This flag is a shortcut for three flags: --experimental_inmemory_jdeps_files, -- experimental_inmemory_dotd_files and -- experimental_remote_download_outputs=minimal.
Expands to:
  --nobuild_runfile_links
  --experimental_inmemory_jdeps_files

Tags: affects_outputs
--remote_download_outputs=<all, minimal or toplevel> default: "all": If set to 'minimal' doesn't download any remote build outputs to the local machine, except the ones required by local actions. If set to ' toplevel' behaves like'minimal' except that it also downloads outputs of top level targets to the local machine. Both options can significantly reduce build times if network bandwidth is a bottleneck.
Tags: affects_outputs
--remote_download_toplevel: Only downloads remote outputs of top level targets to the local machine. This flag is a shortcut for three flags: --experimental_inmemory_jdeps_files, -- experimental_inmemory_dotd_files and -- experimental_remote_download_outputs=toplevel.
Expands to:
  --experimental_inmemory_jdeps_files
  --experimental_inmemory_dotd_files

--symlink_prefix=<a string> default: see description: The prefix that is prepended to any of the convenience symlinks that are created after a build. If omitted, the default value is the name of the build tool followed by a hyphen. If '/' is passed, then no symlinks are created and no warning is emitted. Warning: the special functionality for ' /' will be deprecated soon; use --experimental_convenience_symlinks=ignore instead.

--progress_report_interval=<an integer in 0-3600 range> default: "0": The number of seconds to wait between two reports on still running jobs. The default value 0 means to use the default 10:30:60 incremental algorithm.
Tags: affects_outputs
--show_result=<an integer> default: "1": Show the results of the build. For each target, state whether or not it was brought up-to-date, and if so, a list of output files that were built. The printed files are convenient strings for copy+pasting to the shell, to execute them. This option requires an integer argument, which is the threshold number of targets above which result information is not printed. Thus zero causes suppression of the message and MAX_INT causes printing of the result to occur always. The default is one.

--[no]remote_upload_local_results default: "true": Whether to upload locally executed action results to the remote cache.
--[no]remote_verify_downloads default: "true": If set to true, Bazel will compute the hash sum of all remote downloads and discard the remotely cached values if they don't match the expected value.

--auto_output_filter=<none, all, packages or subpackages> default: "none": If --output_filter is not specified, then the value for this option is used create a filter automatically. Allowed values are 'none' (filter nothing / show everything), 'all' (filter everything / show nothing), 'packages' (include output from rules in packages mentioned on the Bazel command line), and 'subpackages' (like 'packages', but also include subpackages). For the 'packages' and 'subpackages' values //java/foo and //javatests/foo are treated as one package)'.
--[no]build_manual_tests default: "false": Forces test targets tagged 'manual' to be built. 'manual' tests are excluded from processing. This option forces them to be built (but not executed).
--build_tag_filters=<comma-separated list of options> default: "": Specifies a comma-separated list of tags. Each tag can be optionally preceded with '-' to specify excluded tags. Only those targets will be built that contain at least one included tag and do not contain any excluded tags. This option does not affect the set of tests executed with the 'test' command; those are be governed by the test filtering options, for example ' --test_tag_filters'
--[no]build_tests_only default: "false": If specified, only *_test and test_suite rules will be built and other targets specified on the command line will be ignored. By default everything that was requested will be built.
--[no]check_tests_up_to_date default: "false": Don't run tests, just check if they are up-to-date. If all tests results are up-to-date, the testing completes successfully. If any test needs to be built or executed, an error is reported and the testing fails. This option implies --check_up_to_date behavior.
--[no]check_up_to_date default: "false": Don't perform the build, just check if it is up-to-date. If all targets are up-to-date, the build completes successfully. If any step needs to be executed an error is reported and the build fails.
--combined_report=<none or lcov> default: "none": Specifies desired cumulative coverage report type. At this point only LCOV is supported.
--[no]compile_one_dependency default: "false": Compile a single dependency of the argument files. This is useful for syntax checking source files in IDEs, for example, by rebuilding a single target that depends on the source file to detect errors as early as possible in the edit/build/test cycle. This argument affects the way all non-flag arguments are interpreted; instead of being targets to build they are source filenames. For each source filename an arbitrary target that depends on it will be built.
--deleted_packages=<comma-separated list of package names> default: "": A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path. Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package_path entry. Specifying --deleted_packages x/y avoids this problem.
--[no]discard_analysis_cache default: "false": Discard the analysis cache immediately after the analysis phase completes. Reduces memory usage by ~10%, but makes further incremental builds slower.

--execution_log_json_file=<a path> default: see description: Log the executed spawns into this file as json representation of the delimited Spawn protos.
--[no]expand_test_suites default: "true": Expand test_suite targets into their constituent tests before analysis. When this flag is turned on (the default), negative target patterns will apply to the tests belonging to the test suite, otherwise they will not. Turning off this flag is useful when top-level aspects are applied at command line: then they can analyze test_suite targets.
Tags: loading_and_analysis

--[no]experimental_local_memory_estimate default: "false": Estimate the actual memory available online. By default, Bazel assumes most actions use a fixed amount of memory, and counts that against the total available system memory, regardless of how much memory is actually available. This option enables online estimation of how much memory is available at any given time, and thus does not require accurate estimation of how much memory a given action will take.
--[no]experimental_materialize_param_files_directly default: "false": If materializing param files, do so with direct writes to disk.
--experimental_persistent_javac: Enable the experimental persistent Java compiler.

  --strategy=Turbine=local
--experimental_spawn_scheduler: Enable dynamic execution by running actions locally and remotely in parallel. Bazel spawns each action locally and remotely and picks the one that completes first. If an action supports workers, the local action will be run in the persistent worker mode. To enable dynamic execution for an individual action mnemonic, use the `--internal_spawn_scheduler` and `--strategy=<mnemonic> =dynamic` flags instead.
Expands to:
--internal_spawn_scheduler
--spawn_strategy=dynamic
--flaky_test_attempts=<a positive integer, the string "default", or test_regex@attempts. This flag may be passed more than once> multiple uses are accumulated: Each test will be retried up to the specified number of times in case of any test failure. Tests that required more than one attempt to pass would be marked as 'FLAKY' in the test summary. If this option is set, it should specify an int N or the string 'default'. If it's an int, then all tests will be run up to N times. If it is not specified or its value is ' default', then only a single test attempt will be made for regular tests and three for tests marked explicitly as flaky by their rule (flaky=1 attribute).
--genrule_strategy=<comma-separated list of options> default: "": Specify how to execute genrules. This flag will be phased out. Instead, use -- spawn_strategy=<value> to control all actions or --strategy=Genrule=< value> to control genrules only.
--google_auth_scopes=<comma-separated list of options> default: "https://www.googleapis.com/auth/cloud-platform": A comma-separated list of Google Cloud authentication scopes.
--google_credentials=<a string> default: see description: Specifies the file to get authentication credentials from. See https://cloud. google.com/docs/authentication for details.

--[no]ignore_unsupported_sandboxing default: "false": Do not print a warning when sandboxed execution is not supported on this system.
--[no]incompatible_tls_enabled_removed default: "true": No-op. See #8061 for details.
Tags: incompatible_change, triggered_by_all_incompatible_changes
--local_cpu_resources=<an integer, or "HOST_CPUS", optionally followed by [-|*]<float>.> default: "HOST_CPUS": Explicitly set the number of local CPU threads available to Bazel. Takes an integer, or "HOST_CPUS", optionally followed by [-|*]<float> (eg. HOST_CPUS*.5 to use half the available CPU cores).By default, (" HOST_CPUS"), Bazel will query system configuration to estimate number of CPU cores available for the locally executed build actions. Note: This is a no- op if --local_resources is set.
--local_ram_resources=<an integer, or "HOST_RAM", optionally followed by [-|*]<float>.> default: "HOST_RAM*.67": Explicitly set the amount of local host RAM (in MB) available to Bazel. Takes an integer, or "HOST_RAM", optionally followed by [-|*]<float> (eg. HOST_RAM*.5 to use half the available RAM).By default, ("HOST_RAM*. 67"), Bazel will query system configuration to estimate amount of RAM available for the locally executed build actions and will use 67% of available RAM. Note: This is a no-op if --ram_utilization_factor or --local_resources is set.
--local_resources=<comma-separated available amount of RAM (in MB), CPU (in cores) and available I/O (1.0 being average workstation)> default: see description: Deprecated by '--incompatible_remove_local_resources'. Please use ' --local_ram_resources' and '--local_cpu_resources'
--local_termination_grace_seconds=<an integer> default: "15": Time to wait between terminating a local process due to timeout and forcefully shutting it down.
--local_test_jobs=<an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]<float>) eg. "auto", "HOST_CPUS*.5"> default: "auto": The max number of local test jobs to run concurrently. Takes an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]<float>) eg. "auto", "HOST_CPUS*.5". 0 means local resources will limit the number of local test jobs to run concurrently instead. Setting this greater than the value for --jobs is ineffectual.
--[no]materialize_param_files default: "false": Writes intermediate parameter files to output tree even when using remote action execution. Useful when debugging actions. This is implied by -- subcommands and --verbose_failures.
--override_repository=<an equals-separated mapping of repository name to path> multiple uses are accumulated: Overrides a repository with a local directory.
--package_path=<colon-separated list of options> default: "%workspace%": A colon-separated list of where to look for packages. Elements beginning with '%workspace%' are relative to the enclosing workspace. If omitted or empty, the default is the output of 'bazel info default-package-path'.
--ram_utilization_factor=<an integer> default: "0": This flag will be deprecated. Please use --local_ram_resources.
--[no]resource_autosense default: "false": This flag has no effect, and is deprecated
--sandbox_add_mount_pair=<a single path or a 'source:target' pair> multiple uses are accumulated: Add additional path pair to mount in sandbox.
--sandbox_base=<a string> default: "": Lets the sandbox create its sandbox directories underneath this path. Specify a path on tmpfs (like /run/shm) to possibly improve performance a lot when your build / tests have many input files. Note: You need enough RAM and free space on the tmpfs to hold output and intermediate files generated by running actions.
--sandbox_block_path=<a string> multiple uses are accumulated: For sandboxed actions, disallow access to this path.
--[no]sandbox_debug default: "false": Enables debugging features for the sandboxing feature. This includes two things: first, the sandbox root contents are left untouched after a build (and if sandboxfs is in use, the file system is left mounted); and second, prints extra debugging information on execution. This can help developers of Bazel or Starlark rules with debugging failures due to missing input files, etc.
--[no]sandbox_default_allow_network default: "true": Allow network access by default for actions; this may not work with all sandboxing implementations.
--[no]sandbox_fake_hostname default: "false": Change the current hostname to 'localhost' for sandboxed actions.
--[no]sandbox_fake_username default: "false": Change the current username to 'nobody' for sandboxed actions.

--sandbox_writable_path=<a string> multiple uses are accumulated: For sandboxed actions, make an existing directory writable in the sandbox (if supported by the sandboxing implementation, ignored otherwise).
--[no]show_loading_progress default: "true": If enabled, causes Bazel to print "Loading package:" messages.
--spawn_strategy=<comma-separated list of options> default: "": Specify how spawn actions are executed by default. Accepts a comma-separated list of strategies from highest to lowest priority. For each action Bazel picks the strategy with the highest priority that can execute the action.

--strategy=<a '[name=]value1[,..,valueN]' assignment> multiple uses are accumulated: Specify how to distribute compilation of other spawn actions. Accepts a comma- separated list of strategies from highest to lowest priority. For each action Bazel picks the strategy with the highest priority that can execute the action. The default value is "remote,worker,sandboxed,local".See https://blog. bazel.build/2019/06/19/list-strategy.html for details.
--strategy_regexp=<a '<RegexFilter>=value[,value]' assignment> multiple uses are accumulated: Override which spawn strategy should be used to execute spawn actions that have descriptions matching a certain regex_filter. See --per_file_copt for details onregex_filter matching. The first regex_filter that matches the description is used. This option overrides other flags for specifying strategy. Example: -- strategy_regexp=//foo.*\.cc,-//foo/bar=local means to run actions using local strategy if their descriptions match //foo.*.cc but not //foo/bar. Example: -- strategy_regexp='Compiling.*/bar=local -- strategy_regexp=Compiling=sandboxed will run 'Compiling //foo/bar/baz' with the 'local' strategy, but reversing the order would run it with 'sandboxed'.
--[no]subcommands [-s] default: "false": Display the subcommands executed during a build.
--[no]test_keep_going default: "true": When disabled, any non-passing test will cause the entire build to stop. By default all tests are run, even if some do not pass.
--test_lang_filters=<comma-separated list of options> default: "": Specifies a comma-separated list of test languages. Each language can be optionally preceded with '-' to specify excluded languages. Only those test targets will be found that are written in the specified languages. The name used for each language should be the same as the language prefix in the *_test rule, e.g. one of 'cc', 'java', 'py', etc. This option affects --build_tests_only behavior and the test command.
--test_output=<summary, errors, all or streamed> default: "summary": Specifies desired output mode. Valid values are 'summary' to output only test status summary, 'errors' to also print test logs for failed tests, 'all' to print logs for all tests and 'streamed' to output logs for all tests in real time (this will force tests to be executed locally one at a time regardless of --test_strategy value).
--test_size_filters=<comma-separated list of values: small, medium, large or enormous> default: "": Specifies a comma-separated list of test sizes. Each size can be optionally preceded with '-' to specify excluded sizes. Only those test targets will be found that contain at least one included size and do not contain any excluded sizes. This option affects --build_tests_only behavior and the test command.
--test_strategy=<a string> default: "": Specifies which strategy to use when running tests.
--test_summary=<short, terse, detailed, none or testcase> default: "short": Specifies the desired format ot the test summary. Valid values are ' short' to print information only about tests executed, 'terse', to print information only about unsuccessful tests that were run, ' detailed' to print detailed information about failed test cases, and ' none' to omit the summary.
--test_tag_filters=<comma-separated list of options> default: "": Specifies a comma-separated list of test tags. Each tag can be optionally preceded with '-' to specify excluded tags. Only those test targets will be found that contain at least one included tag and do not contain any excluded tags. This option affects --build_tests_only behavior and the test command.
--test_timeout_filters=<comma-separated list of values: short, moderate, long or eternal> default: "": Specifies a comma-separated list of test timeouts. Each timeout can be optionally preceded with '-' to specify excluded timeouts. Only those test targets will be found that contain at least one included timeout and do not contain any excluded timeouts. This option affects --build_tests_only behavior and the test command.
--test_tmpdir=<a path> default: see description: Specifies the base temporary directory for 'bazel test' to use.
--tls_certificate=<a string> default: see description: Specify a path to a TLS certificate that is trusted to sign server certificates.

--worker_extra_flag=<a 'name=value' assignment> multiple uses are accumulated: Extra command-flags that will be passed to worker processes in addition to -- persistent_worker, keyed by mnemonic (e.g. --worker_extra_flag=Javac=--debug.
--worker_max_instances=<[name=]value, where value is an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]<float>) eg. "auto", "HOST_CPUS*.5"> multiple uses are accumulated: How many instances of a worker process (like the persistent Java compiler) may be launched if you use the 'worker' strategy. May be specified as [name=value] to give a different value per worker mnemonic. Takes an integer, or a keyword ("auto", "HOST_CPUS", "HOST_RAM"), optionally followed by an operation ([-|*]<float>) eg. "auto", "HOST_CPUS*.5". 'auto' calculates a reasonable default based on machine capacity. "=value" sets a default for unspecified mnemonics.

Tags: bazel_internal_configuration
--modify_execution_info=<regex=[+-]key,regex=[+-]key,...> default: "": Add or remove keys from an action's execution info based on action mnemonic. Applies only to actions which support execution info. Many common actions support execution info, e.g. Genrule, CppCompile, Javac, SkylarkAction, TestRunner. When specifying multiple values, order matters because many regexes may apply to the same mnemonic. Syntax: "regex=[+-]key,[+-]key,...". Examples: '.*=+x,.*=-y,.*=+z' adds 'x' and 'z' to, and removes 'y' from, the execution info for all actions. 'Genrule=+requires-x' adds 'requires-x' to the execution info for all Genrule actions. '(?!Genrule).*=-requires-x' removes 'requires-x' from the execution info for all non-Genrule actions.

--[no]incompatible_disallow_legacy_py_provider default: "true": If set to true, native Python rules will neither produce nor consume the legacy "py" provider. Use PyInfo instead. Under this flag, passing the legacy provider to a Python target will be an error.
Tags: loading_and_analysis, incompatible_change, triggered_by_all_incompatible_changes

--[no]allow_analysis_failures default: "false": If true, an analysis failure of a rule target results in the target's propagation of an instance of AnalysisFailureInfo containing the error description, instead of resulting in a build failure.
Tags: loading_and_analysis, experimental
--analysis_testing_deps_limit=<an integer> default: "600": Sets the maximum number of transitive dependencies through a rule attribute with a for_analysis_testing configuration transition. Exceeding this limit will result in a rule error.

Tags: test_runner
--runs_per_test=<a positive integer or test_regex@runs. This flag may be passed more than once> multiple uses are accumulated: Specifies number of times to run each test. If any of those attempts fail for any reason, the whole test would be considered failed. Normally the value specified is just an integer. Example: --runs_per_test=3 will run all tests 3 times. Alternate syntax: regex_filter@runs_per_test. Where runs_per_test stands for an integer value and regex_filter stands for a list of include and exclude regular expression patterns (Also see --instrumentation_filter). Example: -- runs_per_test=//foo/.*,-//foo/bar/.*@3 runs all tests in //foo/ except those under foo/bar three times. This option can be passed multiple times.
--test_env=<a 'name=value' assignment with an optional value part> multiple uses are accumulated: Specifies additional environment variables to be injected into the test runner environment. Variables can be either specified by name, in which case its value will be read from the Bazel client environment, or by the name=value pair. This option can be used multiple times to specify several variables. Used only by the 'bazel test' command.
Tags: test_runner
--test_timeout=<a single integer or comma-separated list of 4 integers> default: "-1": Override the default test timeout values for test timeouts (in secs). If a single positive integer value is specified it will override all categories. If 4 comma-separated integers are specified, they will override the timeouts for short, moderate, long and eternal (in that order). In either form, a value of -1 tells bazel to use its default timeouts for that category.
--tvos_simulator_device=<a string> default: see description: The device to simulate when running an tvOS application in the simulator, e.g. 'Apple TV 1080p'. You can get a list of devices by running 'xcrun simctl list devicetypes' on the machine the simulator will be run on.

--[no]collapse_duplicate_defines default: "false": When enabled, redundant --defines will be removed early in the build. This avoids unnecessary loss of the analysis cache for certain types of equivalent builds.
Tags: loading_and_analysis, loses_incremental_state
--[no]distinct_host_configuration default: "true": Build all the tools used during the build for a distinct configuration from that used for the target program. When this is disabled, the same configuration is used for host and target programs. This may cause undesirable rebuilds of tools such as the protocol compiler (and then everything downstream) whenever a minor change is made to the target configuration, such as setting the linker options. When this is enabled (the default), a distinct configuration will be used to build the tools, preventing undesired rebuilds. However, certain libraries will then need to be compiled twice, once for each configuration, which may cause some builds to be slower. As a rule of thumb, this option is likely to benefit users that make frequent changes in configuration (e.g. opt/dbg). Please read the user manual for the full explanation.

Tags: changes_inputs, loading_and_analysis
--[no]parse_headers_verifies_modules default: "false": If enabled, the parse_headers feature verifies that a header module can be built for the target in question instead of doing a separate compile of the header.
Tags: loading_and_analysis, changes_inputs
--[no]process_headers_in_dependencies default: "false": When building a target //a:a, process headers in all targets that //a:a depends on (if header processing is enabled for the toolchain).
Tags: execution
--[no]trim_test_configuration default: "false": When enabled, test-related options will be cleared below the top level of the build. When this flag is active, tests cannot be built as dependencies of non- test rules, but changes to test-related options will not cause non-test rules to be re-analyzed.
Tags: loading_and_analysis, loses_incremental_state
--[no]use_singlejar_apkbuilder default: "true": Build Android APKs with SingleJar.

Tags: affects_outputs
--progress_report_interval=<an integer in 0-3600 range> default: "0": The number of seconds to wait between two reports on still running jobs. The default value 0 means to use the default 10:30:60 incremental algorithm.
Tags: affects_outputs
--show_result=<an integer> default: "1": Show the results of the build. For each target, state whether or not it was brought up-to-date, and if so, a list of output files that were built. The printed files are convenient strings for copy+pasting to the shell, to execute them. This option requires an integer argument, which is the threshold number of targets above which result information is not printed. Thus zero causes suppression of the message and MAX_INT causes printing of the result to occur always. The default is one.
Tags: affects_outputs
--[no]toolchain_resolution_debug default: "false": Print debug information while finding toolchains for a rule. This might help developers of Bazel or Starlark rules with debugging failures due to missing toolchains.

--[no]incompatible_default_to_explicit_init_py default: "false": This flag changes the default behavior so that __init__.py files are no longer automatically created in the runfiles of Python targets. Precisely, when a py_binary or py_test target has legacy_create_init set to "auto" (the default), it is treated as false if and only if this flag is set. See https: //github.com/bazelbuild/bazel/issues/10076.
Tags: affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_py2_outputs_are_suffixed default: "true": If true, targets built in the Python 2 configuration will appear under an output root that includes the suffix '-py2', while targets built for Python 3 will appear in a root with no Python-related suffix. This means that the `bazel-bin` convenience symlink will point to Python 3 targets rather than Python 2. If you enable this option it is also recommended to enable `-- incompatible_py3_is_default`.
Tags: affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_py3_is_default default: "true": If true, `py_binary` and `py_test` targets that do not set their `python_version` (or `default_python_version`) attribute will default to PY3 rather than to PY2. If you set this flag it is also recommended to set `-- incompatible_py2_outputs_are_suffixed`.
Tags: loading_and_analysis, affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_use_python_toolchains default: "true": If set to true, executable native Python rules will use the Python runtime specified by the Python toolchain, rather than the runtime given by legacy flags like --python_top.
Tags: loading_and_analysis, incompatible_change, triggered_by_all_incompatible_changes
--python_version=<PY2 or PY3> default: see description: The Python major version mode, either `PY2` or `PY3`. Note that this is overridden by `py_binary` and `py_test` targets (even if they don't explicitly specify a version) so there is usually not much reason to supply this flag.
Tags: loading_and_analysis, affects_outputs
--target_pattern_file=<a string> default: "": If set, build will read patterns from the file named here, rather than on the command line. It is an error to specify a file here as well as command-line patterns.
Tags: changes_inputs

--[no]build_manual_tests default: "false": Forces test targets tagged 'manual' to be built. 'manual' tests are excluded from processing. This option forces them to be built (but not executed).
--build_tag_filters=<comma-separated list of options> default: "": Specifies a comma-separated list of tags. Each tag can be optionally preceded with '-' to specify excluded tags. Only those targets will be built that contain at least one included tag and do not contain any excluded tags. This option does not affect the set of tests executed with the 'test' command; those are be governed by the test filtering options, for example ' --test_tag_filters'
--[no]build_tests_only default: "false": If specified, only *_test and test_suite rules will be built and other targets specified on the command line will be ignored. By default everything that was requested will be built.
--[no]cache_test_results [-t] default: "auto": If set to 'auto', Bazel reruns a test if and only if: (1) Bazel detects changes in the test or its dependencies, (2) the test is marked as external, (3) multiple test runs were requested with --runs_per_test, or(4) the test previously failed. If set to 'yes', Bazel caches all test results except for tests marked as external. If set to 'no', Bazel does not cache any test results.
--check_constraint=<a string> multiple uses are accumulated: Check the listed constraint.
--[no]check_tests_up_to_date default: "false": Don't run tests, just check if they are up-to-date. If all tests results are up-to-date, the testing completes successfully. If any test needs to be built or executed, an error is reported and the testing fails. This option implies --check_up_to_date behavior.
--[no]check_up_to_date default: "false": Don't perform the build, just check if it is up-to-date. If all targets are up-to-date, the build completes successfully. If any step needs to be executed an error is reported and the build fails.
--[no]compile_one_dependency default: "false": Compile a single dependency of the argument files. This is useful for syntax checking source files in IDEs, for example, by rebuilding a single target that depends on the source file to detect errors as early as possible in the edit/build/test cycle. This argument affects the way all non-flag arguments are interpreted; instead of being targets to build they are source filenames. For each source filename an arbitrary target that depends on it will be built.
--deleted_packages=<comma-separated list of package names> default: "": A comma-separated list of names of packages which the build system will consider non-existent, even if they are visible somewhere on the package path. Use this option when deleting a subpackage 'x/y' of an existing package 'x'. For example, after deleting x/y/BUILD in your client, the build system may complain if it encounters a label '//x:y/z' if that is still provided by another package_path entry. Specifying --deleted_packages x/y avoids this problem.
--[no]discard_analysis_cache default: "false": Discard the analysis cache immediately after the analysis phase completes. Reduces memory usage by ~10%, but makes further incremental builds slower.
--execution_log_binary_file=<a path> default: see description: Log the executed spawns into this file as delimited Spawn protos.
--execution_log_json_file=<a path> default: see description: Log the executed spawns into this file as json representation of the delimited Spawn protos.
--[no]expand_test_suites default: "true": Expand test_suite targets into their constituent tests before analysis. When this flag is turned on (the default), negative target patterns will apply to the tests belonging to the test suite, otherwise they will not. Turning off this flag is useful when top-level aspects are applied at command line: then they can analyze test_suite targets.
Tags: loading_and_analysis
--[no]experimental_cancel_concurrent_tests default: "false": If true, then Bazel will cancel concurrently running tests on the first successful run. This is only useful in combination with -- runs_per_test_detects_flakes.
Tags: affects_outputs, loading_and_analysis
--experimental_execution_log_file=<a path> default: see description: Log the executed spawns into this file as delimited Spawn protos.
--experimental_extra_action_filter=<a comma-separated list of regex expressions with prefix '-' specifying excluded paths> default: "": Filters set of targets to schedule extra_actions for.
--[no]experimental_extra_action_top_level_only default: "false": Only schedules extra_actions for top level targets.
--[no]experimental_fetch_all_coverage_outputs default: "false": If true, then Bazel fetches the entire coverage data directory for each test during a coverage run.
Tags: affects_outputs, loading_and_analysis
--[no]experimental_interleave_loading_and_analysis default: "true": No-op.
--[no]experimental_j2objc_header_map default: "true": Whether to generate J2ObjC header map in parallel of J2ObjC transpilation.
--[no]experimental_j2objc_shorter_header_path default: "false": Whether to generate with shorter header path (uses "_ios" instead of "_j2objc").
Tags: affects_outputs
--experimental_java_classpath=<off, javabuilder or bazel> default: "javabuilder": Enables reduced classpaths for Java compilations.
--[no]experimental_local_memory_estimate default: "false": Estimate the actual memory available online. By default, Bazel assumes most actions use a fixed amount of memory, and counts that against the total available system memory, regardless of how much memory is actually available. This option enables online estimation of how much memory is available at any given time, and thus does not require accurate estimation of how much memory a given action will take.
--[no]experimental_materialize_param_files_directly default: "false": If materializing param files, do so with direct writes to disk.
--[no]experimental_persistent_test_runner default: "false": Allows running java_test targets locally within a persistent worker. To enable the persistent test runner one must run bazel test with the flags:-- test_strategy=local --strategy=TestRunner=worker -- experimental_persistent_test_runner
--[no]explicit_java_test_deps default: "false": Explicitly specify a dependency to JUnit or Hamcrest in a java_test instead of accidentally obtaining from the TestRunner's deps. Only works for bazel right now.
--flaky_test_attempts=<a positive integer, the string "default", or test_regex@attempts. This flag may be passed more than once> multiple uses are accumulated: Each test will be retried up to the specified number of times in case of any test failure. Tests that required more than one attempt to pass would be marked as 'FLAKY' in the test summary. If this option is set, it should specify an int N or the string 'default'. If it's an int, then all tests will be run up to N times. If it is not specified or its value is ' default', then only a single test attempt will be made for regular tests and three for tests marked explicitly as flaky by their rule (flaky=1 attribute).
--genrule_strategy=<comma-separated list of options> default: "": Specify how to execute genrules. This flag will be phased out. Instead, use -- spawn_strategy=<value> to control all actions or --strategy=Genrule=< value> to control genrules only.
--host_java_launcher=<a build target label> default: see description: The Java launcher used by tools that are executed during a build.
--host_java_toolchain=<a build target label> default: "@bazel_tools//tools/jdk:remote_toolchain": The Java toolchain used to build tools that are executed during a build.
--host_javabase=<a build target label> default: see description: JAVABASE used for the host JDK. This is the java_runtime which is used to execute tools during a build.
--host_javacopt=<a string> multiple uses are accumulated: Additional options to pass to javac when building tools that are executed during a build.
--[no]incompatible_strict_action_env default: "false": If true, Bazel uses an environment with a static value for PATH and does not inherit LD_LIBRARY_PATH or TMPDIR. Use --action_env=ENV_VARIABLE if you want to inherit specific environment variables from the client, but note that doing so can prevent cross-user caching if a shared cache is used.
Tags: loading_and_analysis, incompatible_change, triggered_by_all_incompatible_changes
--j2objc_translation_flags=<comma-separated list of options> multiple uses are accumulated: Additional options to pass to the J2ObjC tool.
--java_debug: Causes the Java virtual machine of a java test to wait for a connection from a JDWP-compliant debugger (such as jdb) before starting the test. Implies - test_output=streamed.
Expands to:
  --test_arg=--wrapper_script_flag=--debug
  --test_output=streamed
  --test_strategy=exclusive
  --test_timeout=9999
  --nocache_test_results
--[no]java_deps default: "true": Generate dependency information (for now, compile-time classpath) per Java target.
--[no]java_header_compilation default: "true": Compile ijars directly from source.
--java_launcher=<a build target label> default: see description: The Java launcher to use when building Java binaries. The "launcher" attribute overrides this flag.
--java_toolchain=<a build target label> default: "@bazel_tools//tools/jdk:remote_toolchain": The name of the toolchain rule for Java.
--javabase=<a build target label> default: "@bazel_tools//tools/jdk:jdk": JAVABASE used for the JDK invoked by Bazel. This is the java_runtime which will be used to execute external Java commands.
--javacopt=<a string> multiple uses are accumulated: Additional options to pass to javac.
--jvmopt=<a string> multiple uses are accumulated: Additional options to pass to the Java VM. These options will get added to the VM startup options of each java_binary target.
--legacy_main_dex_list_generator=<a build target label> default: see description: Specifies a binary to use to generate the list of classes that must be in the main dex when compiling legacy multidex.
--local_cpu_resources=<an integer, or "HOST_CPUS", optionally followed by [-|*]<float>.> default: "HOST_CPUS": Explicitly set the number of local CPU threads available to Bazel. Takes an integer, or "HOST_CPUS", optionally followed by [-|*]<float> (eg. HOST_CPUS*.5 to use half the available CPU cores).By default, (" HOST_CPUS"), Bazel will query system configuration to estimate number of CPU cores available for the locally executed build actions. Note: This is a no- op if --local_resources is set.
--local_ram_resources=<an integer, or "HOST_RAM", optionally followed by [-|*]<float>.> default: "HOST_RAM*.67": Explicitly set the amount of local host RAM (in MB) available to Bazel. Takes an integer, or "HOST_RAM", optionally followed by [-|*]<float> (eg. HOST_RAM*.5 to use half the available RAM).By default, ("HOST_RAM*. 67"), Bazel will query system configuration to estimate amount of RAM available for the locally executed build actions and will use 67% of available RAM. Note: This is a no-op if --ram_utilization_factor or --local_resources is set.
--local_resources=<comma-separated available amount of RAM (in MB), CPU (in cores) and available I/O (1.0 being average workstation)> default: see description: Deprecated by '--incompatible_remove_local_resources'. Please use ' --local_ram_resources' and '--local_cpu_resources'

--strategy_regexp=<a '<RegexFilter>=value[,value]' assignment> multiple uses are accumulated: Override which spawn strategy should be used to execute spawn actions that have descriptions matching a certain regex_filter. See --per_file_copt for details onregex_filter matching. The first regex_filter that matches the description is used. This option overrides other flags for specifying strategy. Example: -- strategy_regexp=//foo.*\.cc,-//foo/bar=local means to run actions using local strategy if their descriptions match //foo.*.cc but not //foo/bar. Example: -- strategy_regexp='Compiling.*/bar=local -- strategy_regexp=Compiling=sandboxed will run 'Compiling //foo/bar/baz' with the 'local' strategy, but reversing the order would run it with 'sandboxed'.

--test_output=<summary, errors, all or streamed> default: "summary": Specifies desired output mode. Valid values are 'summary' to output only test status summary, 'errors' to also print test logs for failed tests, 'all' to print logs for all tests and 'streamed' to output logs for all tests in real time (this will force tests to be executed locally one at a time regardless of --test_strategy value).
--test_result_expiration=<an integer> default: "-1": This option is deprecated and has no effect.
--[no]test_runner_fail_fast default: "false": Forwards fail fast option to the test runner. The test runner should stop execution upon first failure.
--test_sharding_strategy=<explicit or disabled> default: "explicit": Specify strategy for test sharding: 'explicit' to only use sharding if the 'shard_count' BUILD attribute is present. 'disabled' to never use test sharding.
--test_size_filters=<comma-separated list of values: small, medium, large or enormous> default: "": Specifies a comma-separated list of test sizes.

Only those test targets will be found that contain at least one included tag and do not contain any excluded tags. This option affects --build_tests_only behavior and the test command.
--test_timeout_filters=<comma-separated list of values: short, moderate, long or eternal> default: "": Specifies a comma-separated list of test timeouts. Each timeout can be optionally preceded with '-' to specify excluded timeouts. Only those test targets will be found that contain at least one included timeout and do not contain any excluded timeouts. This option affects --build_tests_only behavior and the test command.
--test_tmpdir=<a path> default: see description: Specifies the base temporary directory for 'bazel test' to use.
--[no]translations default: "auto": Translate Java messages; bundle all translations into the jar for each affected rule.

--aspect_deps=<off, conservative or precise> default: "conservative": How to resolve aspect dependencies when the output format is one of {xml,proto, record}. 'off' means no aspect dependencies are resolved, ' conservative' (the default) means all declared aspect dependencies are added regardless of whether they are given the rule class of direct dependencies, 'precise' means that only those aspects are added that are possibly active given the rule class of the direct dependencies. Note that precise mode requires loading other packages to evaluate a single target thus making it slower than the other modes. Also note that even precise mode is not completely precise: the decision whether to compute an aspect is decided in the analysis phase, which is not run during 'bazel query'.
Tags: build_file_semantics
--[no]implicit_deps default: "true": If enabled, implicit dependencies will be included in the dependency graph over which the query operates. An implicit dependency is one that is not explicitly specified in the BUILD file but added by bazel.
Tags: build_file_semantics
--[no]nodep_deps default: "true": If enabled, deps from "nodep" attributes will be included in the dependency graph over which the query operates. A common example of a " nodep" attribute is "visibility". Run and parse the output of `info build-language` to learn about all the "nodep" attributes in the build language.
Tags: build_file_semantics
--output=<a string> default: "label": The format in which the cquery results should be printed. Allowed values for cquery are: label, label_kind, textproto, transitions, proto, jsonproto. If you select 'transitions', you also have to specify the --transitions= (lite|full) option.
Tags: terminal_output
--[no]proto:default_values default: "true": If true, attributes whose value is not explicitly specified in the BUILD file are included; otherwise they are omitted. This option is applicable to -- output=proto

Tags: build_file_semantics
--[no]proto:include_configurations default: "true": if enabled, proto output will include information about configurations. When disabled,cquery proto output format resembles query output format.
Tags: affects_outputs
--[no]proto:include_synthetic_attribute_hash default: "false": Whether or not to calculate and populate the $internal_attr_hash attribute.

Tags: terminal_output
--[no]relative_locations default: "false": If true, the location of BUILD files in xml and proto outputs will be relative. By default, the location output is an absolute path and will not be consistent across machines. You can set this option to true to have a consistent result across machines.
Tags: terminal_output
--show_config_fragments=<off, direct or transitive> default: "off": Shows the configuration fragments required by a rule and its transitive dependencies. This can be useful for evaluating how much a configured target graph can be trimmed.
Tags: affects_outputs
--[no]tool_deps default: "true": Query: If disabled, dependencies on 'host configuration' or ' execution' targets will not be included in the dependency graph over which the query operates. A 'host configuration' dependency edge, such as the one from any 'proto_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same ' target' program. Cquery: If disabled, filters out all configured targets which cross a host or execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the host configuration, only host configured targets will be returned.
Tags: build_file_semantics
--transitions=<full, lite or none> default: "none": The format in which cquery will print transition information.
Tags: affects_outputs
--universe_scope=<comma-separated list of options> default: "": A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands. For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

Tags: execution
--modify_execution_info=<regex=[+-]key,regex=[+-]key,...> default: "": Add or remove keys from an action's execution info based on action mnemonic. Applies only to actions which support execution info. Many common actions support execution info, e.g. Genrule, CppCompile, Javac, SkylarkAction, TestRunner. When specifying multiple values, order matters because many regexes may apply to the same mnemonic. Syntax: "regex=[+-]key,[+-]key,...". Examples: '.*=+x,.*=-y,.*=+z' adds 'x' and 'z' to, and removes 'y' from, the execution info for all actions. 'Genrule=+requires-x' adds 'requires-x' to the execution info for all Genrule actions. '(?!Genrule).*=-requires-x' removes 'requires-x' from the execution info for all non-Genrule actions.

Tags: test_runner
--ios_simulator_version=<a dotted version (for example '2.3' or '3.3alpha2.4')> default: see description: The version of iOS to run on the simulator when running or testing. This is ignored for ios_test rules if a target device is specified in the rule.
Tags: test_runner
--runs_per_test=<a positive integer or test_regex@runs. This flag may be passed more than once> multiple uses are accumulated: Specifies number of times to run each test. If any of those attempts fail for any reason, the whole test would be considered failed. Normally the value specified is just an integer. Example: --runs_per_test=3 will run all tests 3 times. Alternate syntax: regex_filter@runs_per_test. Where runs_per_test stands for an integer value and regex_filter stands for a list of include and exclude regular expression patterns (Also see --instrumentation_filter). Example: -- runs_per_test=//foo/.*,-//foo/bar/.*@3 runs all tests in //foo/ except those under foo/bar three times. This option can be passed multiple times.
--test_env=<a 'name=value' assignment with an optional value part> multiple uses are accumulated: Specifies additional environment variables to be injected into the test runner environment. Variables can be either specified by name, in which case its value will be read from the Bazel client environment, or by the name=value pair. This option can be used multiple times to specify several variables. Used only by the 'bazel test' command.
Tags: test_runner
--test_timeout=<a single integer or comma-separated list of 4 integers> default: "-1": Override the default test timeout values for test timeouts (in secs). If a single positive integer value is specified it will override all categories. If 4 comma-separated integers are specified, they will override the timeouts for short, moderate, long and eternal (in that order). In either form, a value of -1 tells bazel to use its default timeouts for that category.
--tvos_simulator_device=<a string> default: see description: The device to simulate when running an tvOS application in the simulator, e.g. 'Apple TV 1080p'. You can get a list of devices by running 'xcrun simctl list devicetypes' on the machine the simulator will be run on.

Tags: test_runner

--aspect_deps=<off, conservative or precise> default: "conservative": How to resolve aspect dependencies when the output format is one of {xml,proto, record}. 'off' means no aspect dependencies are resolved, ' conservative' (the default) means all declared aspect dependencies are added regardless of whether they are given the rule class of direct dependencies, 'precise' means that only those aspects are added that are possibly active given the rule class of the direct dependencies. Note that precise mode requires loading other packages to evaluate a single target thus making it slower than the other modes. Also note that even precise mode is not completely precise: the decision whether to compute an aspect is decided in the analysis phase, which is not run during 'bazel query'.
Tags: build_file_semantics
--[no]implicit_deps default: "true": If enabled, implicit dependencies will be included in the dependency graph over which the query operates. An implicit dependency is one that is not explicitly specified in the BUILD file but added by bazel.
Tags: build_file_semantics
--[no]nodep_deps default: "true": If enabled, deps from "nodep" attributes will be included in the dependency graph over which the query operates. A common example of a " nodep" attribute is "visibility". Run and parse the output of `info build-language` to learn about all the "nodep" attributes in the build language.
Tags: build_file_semantics
--output=<a string> default: "label": The format in which the cquery results should be printed. Allowed values for cquery are: label, label_kind, textproto, transitions, proto, jsonproto. If you select 'transitions', you also have to specify the --transitions= (lite|full) option.
Tags: terminal_output
--[no]proto:default_values default: "true": If true, attributes whose value is not explicitly specified in the BUILD file are included; otherwise they are omitted. This option is applicable to -- output=proto
Tags: terminal_output
--[no]proto:flatten_selects default: "true": If enabled, configurable attributes created by select() are flattened. For list types the flattened representation is a list containing each value of the select map exactly once. Scalar types are flattened to null.
Tags: build_file_semantics
--[no]proto:include_configurations default: "true": if enabled, proto output will include information about configurations. When disabled,cquery proto output format resembles query output format.
Tags: affects_outputs
--[no]proto:include_synthetic_attribute_hash default: "false": Whether or not to calculate and populate the $internal_attr_hash attribute.
Tags: terminal_output
--[no]proto:locations default: "true": Whether to output location information in proto output at all.
Tags: terminal_output
--proto:output_rule_attrs=<comma-separated list of options> default: "all": Comma separated list of attributes to include in output. Defaults to all attributes. Set to empty string to not output any attribute. This option is applicable to --output=proto.
Tags: terminal_output
--[no]proto:rule_inputs_and_outputs default: "true": Whether or not to populate the rule_input and rule_output fields.
Tags: terminal_output
--[no]relative_locations default: "false": If true, the location of BUILD files in xml and proto outputs will be relative. By default, the location output is an absolute path and will not be consistent across machines. You can set this option to true to have a consistent result across machines.
Tags: terminal_output
--show_config_fragments=<off, direct or transitive> default: "off": Shows the configuration fragments required by a rule and its transitive dependencies. This can be useful for evaluating how much a configured target graph can be trimmed.
Tags: affects_outputs
--[no]tool_deps default: "true": Query: If disabled, dependencies on 'host configuration' or ' execution' targets will not be included in the dependency graph over which the query operates. A 'host configuration' dependency edge, such as the one from any 'proto_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same ' target' program. Cquery: If disabled, filters out all configured targets which cross a host or execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the host configuration, only host configured targets will be returned.
Tags: build_file_semantics
--transitions=<full, lite or none> default: "none": The format in which cquery will print transition information.
Tags: affects_outputs
--universe_scope=<comma-separated list of options> default: "": A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands. For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.
Tags: loading_and_analysis

--[no]collapse_duplicate_defines default: "false": When enabled, redundant --defines will be removed early in the build. This avoids unnecessary loss of the analysis cache for certain types of equivalent builds.
Tags: loading_and_analysis, loses_incremental_state
--[no]distinct_host_configuration default: "true": Build all the tools used during the build for a distinct configuration from that used for the target program. When this is disabled, the same configuration is used for host and target programs. This may cause undesirable rebuilds of tools such as the protocol compiler (and then everything downstream) whenever a minor change is made to the target configuration, such as setting the linker options. When this is enabled (the default), a distinct configuration will be used to build the tools, preventing undesired rebuilds. However, certain libraries will then need to be compiled twice, once for each configuration, which may cause some builds to be slower. As a rule of thumb, this option is likely to benefit users that make frequent changes in configuration (e.g. opt/dbg). Please read the user manual for the full explanation.
Tags: loses_incremental_state, bazel_internal_configuration, loading_and_analysis
--[no]experimental_filter_library_jar_with_program_jar default: "false": Filter the ProGuard ProgramJar to remove any classes also present in the LibraryJar.

Tags: execution
--[no]trim_test_configuration default: "false": When enabled, test-related options will be cleared below the top level of the build. When this flag is active, tests cannot be built as dependencies of non- test rules, but changes to test-related options will not cause non-test rules to be re-analyzed.
Tags: loading_and_analysis, loses_incremental_state
--[no]use_singlejar_apkbuilder default: "true": Build Android APKs with SingleJar.
Tags: loading_and_analysis

--[no]toolchain_resolution_debug default: "false": Print debug information while finding toolchains for a rule. This might help developers of Bazel or Starlark rules with debugging failures due to missing toolchains.
Tags: terminal_output

--[no]incompatible_default_to_explicit_init_py default: "false": This flag changes the default behavior so that __init__.py files are no longer automatically created in the runfiles of Python targets. Precisely, when a py_binary or py_test target has legacy_create_init set to "auto" (the default), it is treated as false if and only if this flag is set. See https: //github.com/bazelbuild/bazel/issues/10076.
Tags: affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_py2_outputs_are_suffixed default: "true": If true, targets built in the Python 2 configuration will appear under an output root that includes the suffix '-py2', while targets built for Python 3 will appear in a root with no Python-related suffix. This means that the `bazel-bin` convenience symlink will point to Python 3 targets rather than Python 2. If you enable this option it is also recommended to enable `-- incompatible_py3_is_default`.
Tags: affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_py3_is_default default: "true": If true, `py_binary` and `py_test` targets that do not set their `python_version` (or `default_python_version`) attribute will default to PY3 rather than to PY2. If you set this flag it is also recommended to set `-- incompatible_py2_outputs_are_suffixed`.
Tags: loading_and_analysis, affects_outputs, incompatible_change, triggered_by_all_incompatible_changes
--[no]incompatible_use_python_toolchains default: "true": If set to true, executable native Python rules will use the Python runtime specified by the Python toolchain, rather than the runtime given by legacy flags like --python_top.
Tags: loading_and_analysis, incompatible_change, triggered_by_all_incompatible_changes
--python_version=<PY2 or PY3> default: see description: The Python major version mode, either `PY2` or `PY3`. Note that this is overridden by `py_binary` and `py_test` targets (even if they don't explicitly specify a version) so there is usually not much reason to supply this flag.
Tags: loading_and_analysis, affects_outputs

--[no]cache_test_results [-t] default: "auto": If set to 'auto', Bazel reruns a test if and only if: (1) Bazel detects changes in the test or its dependencies, (2) the test is marked as external, (3) multiple test runs were requested with --runs_per_test, or(4) the test previously failed. If set to 'yes', Bazel caches all test results except for tests marked as external. If set to 'no', Bazel does not cache any test results.
--check_constraint=<a string> multiple uses are accumulated: Check the listed constraint.
--[no]experimental_cancel_concurrent_tests default: "false": If true, then Bazel will cancel concurrently running tests on the first successful run. This is only useful in combination with -- runs_per_test_detects_flakes.

--[no]incompatible_strict_action_env default: "false": If true, Bazel uses an environment with a static value for PATH and does not inherit LD_LIBRARY_PATH or TMPDIR. Use --action_env=ENV_VARIABLE if you want to inherit specific environment variables from the client, but note that doing so can prevent cross-user caching if a shared cache is used.

--shell_executable=<a path> default: see description: Absolute path to the shell executable for Bazel to use. If this is unset, but the BAZEL_SH environment variable is set on the first Bazel invocation (that starts up a Bazel server), Bazel uses that. If neither is set, Bazel uses a hard-coded default path depending on the operating system it runs on (Windows: c:/tools/msys64/usr/bin/bash.exe, FreeBSD: /usr/local/bin/bash, all others: /bin/bash). Note that using a shell that is not compatible with bash may lead to build failures or runtime failures of the generated binaries.

A 'host configuration' dependency edge, such as the one from any 'proto_library' rule to the Protocol Compiler, usually points to a tool executed during the build rather than a part of the same ' target' program. Cquery: If disabled, filters out all configured targets which cross a host or execution transition from the top-level target that discovered this configured target. That means if the top-level target is in the target configuration, only configured targets also in the target configuration will be returned. If the top-level target is in the host configuration, only host configured targets will be returned.
Tags: build_file_semantics
--universe_scope=<comma-separated list of options> default: "": A comma-separated set of target patterns (additive and subtractive). The query may be performed in the universe defined by the transitive closure of the specified targets. This option is used for the query and cquery commands. For cquery, the input to this option is the targets all answers are built under and so this option may affect configurations and transitions. If this option is not specified, the top-level targets are assumed to be the targets parsed from the query expression. Note: For cquery, not specifying this option may cause the build to break if targets parsed from the query expression are not buildable with top-level options.

Option Effect Tags

`unknown`	This option has unknown, or undocumented, effect.
`no_op`	This option has literally no effect.
`loses_incremental_state`	Changing the value of this option can cause significant loss of incremental state, which slows builds. State could be lost due to a server restart or to invalidation of a large part of the dependency graph.
`changes_inputs`	This option actively changes the inputs that bazel considers for the build, such as filesystem restrictions, repository versions, or other options.
`affects_outputs`	This option affects bazel's outputs. This tag is intentionally broad, can include transitive affects, and does not specify the type of output it affects.
`build_file_semantics`	This option affects the semantics of BUILD or .bzl files.
`bazel_internal_configuration`	This option affects settings of bazel-internal machinery. This tag does not, on its own, mean that build artifacts are affected.
`loading_and_analysis`	This option affects the loading and analysis of dependencies, and the building of the dependency graph.
`execution`	This option affects the execution phase, such as sandboxing or remote execution related options.
`host_machine_resource_optimizations`	This option triggers an optimization that may be machine specific and is not guaranteed to work on all machines. The optimization could include a tradeoff with other aspects of performance, such as memory or cpu cost.
`eagerness_to_exit`	This option changes how eagerly bazel will exit from a failure, where a choice between continuing despite the failure and ending the invocation exists.
`bazel_monitoring`	This option is used to monitor bazel's behavior and performance.
`terminal_output`	This option affects bazel's terminal output.
`action_command_lines`	This option changes the command line arguments of one or more build actions.
`test_runner`	This option changes the testrunner environment of the build.

Option Metadata Tags

`experimental`	This option triggers an experimental feature with no guarantees of functionality.
`incompatible_change`	This option triggers a breaking change. Use this option to test your migration readiness or get early access to the new feature
`deprecated`	This option is deprecated. It might be that the feature it affects is deprecated, or that another method of supplying the information is preferred.
`triggered_by_all_incompatible_changes`	This option is triggered by the expansion option --all_incompatible_changes.
