Manage your Bazel environment

Master your Bazel environment with Bazenv

Bazel is fiddly. Projects that compile with one version of Bazel don't work with another, and keeping multiple versions of Bazel around is a pain. Bazenv solves this problem by managing your Bazel version on a project by project basis. Bazenv is inspired by jenv and rbenv, which solve the same problem for Java and Ruby.

Installation

1. Bazenv is built with go. To download: go get -d github.com/salesforce/bazenv/...
2. Install Bazenv with make deps install. This will build bazenv and its bazel stub.
3. Make sure $GOHOME/bin is at the beginning of your path.
4. Install a version of Bazel with bazenv install <version>.
5. Set the global Bazel version with bazenv global <version>.

Installing additional Bazel versions

• Use bazenv install to download and install any Bazel version on Bazel's Github releases page.
• Use bazenv add to add an existing Bazel install directory to Bazenv.

Choosing which Bazel version to run

• To see all available Bazel versions, use bazenv list.
• Use bazenv global to set the global Bazel version. This version will be used unless specifically overridden with a local version.
• Use bazenv local to set a local Bazel version for a given directory. This version will be used for all child directories.

How Bazenv works

• Bazenv stores configuration and all installed Bazel versions in the ~/.bazenv directory.
• .bazenv_version files are used to configure the local Bazel version.
• The Bazenv bazel shim reads from Bazenv's configuration to locate the correct Bazel binary and execute it.

Troubleshooting

• Make sure Bazenv's bazel shim is before any other bazel binary on your path.
• bazenv doctor will evaluate your Bazenv environment.
