[[repository_cache]]
To accelerate fetches, local repository cache can be activated. This cache is
only used for rules_closure external repository and transitive dependendcies.
That's because rules_closure uses standard Bazel download facility. For all
other gerrit dependencies, the download_artifacts repository cache is used
already.
To activate the local repository cache, create accessible cache directory:
----
mkdir -p ~/.gerritcodereview/bazel-cache/repository
----
and add this line to your `~/.bazelrc` file:
----
build --experimental_repository_cache=/home/<user>/.gerritcodereview/bazel-cache/repository
----
[NOTE] `experimental_repository_cache` must be absolute path. Expansion of `~` is
unfortunately not supported yet. This is also the reason why we can't activate this
feature by default yet (by adjusting tools/bazel.rc file).
