Installing Bazel on Ubuntu
Supported Ubuntu Linux platforms:
- 18.04 (LTS)
- 16.04 (LTS)
Bazel will probably work fine on other Ubuntu releases and Debian stretch and above, but we currently do not test this on Bazel’s CI and thus can’t promise it.
Install Bazel on Ubuntu using one of the following methods:
- Use Bazelisk (recommended)
- Use our custom APT repository
- Use the binary installer
- Compile Bazel from source
Bazel comes with two completion scripts. After installing Bazel, you can:
Using Bazel's apt repository
Step 1: Add Bazel distribution URI as a package source
Note: This is a one-time setup step.
sudo apt install curl gnupg curl -fsSL https://bazel.build/bazel-release.pub.gpg | gpg --dearmor > bazel.gpg sudo mv bazel.gpg /etc/apt/trusted.gpg.d/ echo "deb [arch=amd64] https://storage.googleapis.com/bazel-apt stable jdk1.8" | sudo tee /etc/apt/sources.list.d/bazel.list
The component name “jdk1.8” is kept for legacy reasons only and doesn’t relate to supported or included JDK versions anymore. In the past, when Bazel did not yet bundle a private JRE, we had two release versions, one compatible with JDK 7 and one with JDK 8. However, since we dropped Java 7 support and started bundling a private runtime, Bazel releases are Java version agnostic. Changing the “jdk1.8” component name would break existing users of the repo though.
Step 2: Install and update Bazel
sudo apt update && sudo apt install bazel
Once installed, you can upgrade to a newer version of Bazel as part of your normal system updates:
sudo apt update && sudo apt full-upgrade
bazel package will always install the latest stable version of Bazel. You
can install specific, older versions of Bazel in addition to the latest one like
sudo apt install bazel-1.0.0
This will install Bazel 1.0.0 as
/usr/bin/bazel-1.0.0 on your system. This
can be useful if you need a specific version of Bazel to build a project, e.g.
because it uses a
.bazelversion file to explicitly state with which Bazel
version it should be built.
Optionally, you can set
bazel to a specific version by creating a symlink:
sudo ln -s /usr/bin/bazel-1.0.0 /usr/bin/bazel bazel --version # 1.0.0
Step 3: Install a JDK (optional)
Bazel includes a private, bundled JRE as its runtime and doesn’t require you to install any specific version of Java.
However, if you want to build Java code using Bazel, you have to install a JDK.
# Ubuntu 16.04 (LTS) uses OpenJDK 8 by default: sudo apt install openjdk-8-jdk # Ubuntu 18.04 (LTS) uses OpenJDK 11 by default: sudo apt install openjdk-11-jdk
Using the binary installer
While we generally recommend to use the apt repository, the binary installer can be useful in case you don’t have admin permissions on your machine or can’t add custom repositories.
The binary installers can be downloaded from Bazel’s GitHub releases page.
The installer contains the Bazel binary and extracts it into your
folder. Some additional libraries must be installed manually for Bazel to work.
Step 1: Install required packages
Bazel needs a C++ compiler and unzip / zip in order to work:
sudo apt install g++ unzip zip
If you want to build Java code using Bazel, install a JDK:
# Ubuntu 16.04 (LTS) uses OpenJDK 8 by default: sudo apt-get install openjdk-8-jdk # Ubuntu 18.04 (LTS) uses OpenJDK 11 by default: sudo apt-get install openjdk-11-jdk
Step 2: Run the installer
Next, download the Bazel binary installer named
from the Bazel releases page on GitHub.
Run it as follows:
chmod +x bazel-<version>-installer-linux-x86_64.sh ./bazel-<version>-installer-linux-x86_64.sh --user
--user flag installs Bazel to the
$HOME/bin directory on your system and
.bazelrc path to
$HOME/.bazelrc. Use the
--help command to see
additional installation options.
Step 3: Set up your environment
If you ran the Bazel installer with the
--user flag as above, the Bazel
executable is installed in your
$HOME/bin directory. It’s a good idea to add
this directory to your default paths, as follows:
You can also add this command to your
~/.zshrc file to make it
