JavaToolchainInfo

Provides access to information about the Java toolchain rule. Accessible as a 'java_toolchain' field on a Target struct.

bootclasspath

depset JavaToolchainInfo.bootclasspath

The Java target bootclasspath entries. Corresponds to javac's -bootclasspath flag.

jacocorunner

FilesToRunProvider JavaToolchainInfo.jacocorunner

The jacocorunner used by the toolchain. May return None.

java_runtime

JavaRuntimeInfo JavaToolchainInfo.java_runtime

The java runtime information.

jvm_opt

depset JavaToolchainInfo.jvm_opt

The default options for the JVM running the java compiler and associated tools.

one_version_allowlist

File JavaToolchainInfo.one_version_allowlist

The allowlist used by the One-Version compliance checker May return None.

one_version_tool

File JavaToolchainInfo.one_version_tool

The artifact that enforces One-Version compliance of java binaries. May return None.

single_jar

File JavaToolchainInfo.single_jar

The SingleJar deploy jar.

source_version

string JavaToolchainInfo.source_version

The java source version.

target_version

string JavaToolchainInfo.target_version

The java target version.

timezone_data

File JavaToolchainInfo.timezone_data()

The latest timezone data resource jar that can be loaded by java binaries May return None.

to_json

string JavaToolchainInfo.to_json()

Deprecated. This API is deprecated and will be removed soon. Please do not depend on it. It is disabled with ---incompatible_struct_has_no_methods. Use this flag to verify your code is compatible with its imminent removal.
Creates a JSON string from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs, a list of these types or a dictionary with string keys and values of these types. Quotes and new lines in strings are escaped. Examples:

struct(key=123).to_json()
# {"key":123}

struct(key=True).to_json()
# {"key":true}

struct(key=[1, 2, 3]).to_json()
# {"key":[1,2,3]}

struct(key='text').to_json()
# {"key":"text"}

struct(key=struct(inner_key='text')).to_json()
# {"key":{"inner_key":"text"}}

struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_json()
# {"key":[{"inner_key":1},{"inner_key":2}]}

struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_json()
# {"key":{"inner_key":{"inner_inner_key":"text"}}}

.

Deprecated: instead, use json.encode(x) or json.encode_indent(x), which work for values other than structs and do not pollute the struct field namespace.

to_proto

string JavaToolchainInfo.to_proto()

Deprecated. This API is deprecated and will be removed soon. Please do not depend on it. It is disabled with ---incompatible_struct_has_no_methods. Use this flag to verify your code is compatible with its imminent removal.
Creates a text message from the struct parameter. This method only works if all struct elements (recursively) are strings, ints, booleans, other structs or dicts or lists of these types. Quotes and new lines in strings are escaped. Struct keys are iterated in the sorted order. Examples:

struct(key=123).to_proto()
# key: 123

struct(key=True).to_proto()
# key: true

struct(key=[1, 2, 3]).to_proto()
# key: 1
# key: 2
# key: 3

struct(key='text').to_proto()
# key: "text"

struct(key=struct(inner_key='text')).to_proto()
# key {
#   inner_key: "text"
# }

struct(key=[struct(inner_key=1), struct(inner_key=2)]).to_proto()
# key {
#   inner_key: 1
# }
# key {
#   inner_key: 2
# }

struct(key=struct(inner_key=struct(inner_inner_key='text'))).to_proto()
# key {
#    inner_key {
#     inner_inner_key: "text"
#   }
# }

struct(foo={4: 3, 2: 1}).to_proto()
# foo: {
#   key: 4
#   value: 3
# }
# foo: {
#   key: 2
#   value: 1
# }

Deprecated: use proto.encode_text(x) instead.

tools

depset JavaToolchainInfo.tools

The compilation tools.
