Bazel’s implicit dependencies are fetched over the network while running for the
first time. However, this may cause problems when running Bazel in an airgapped

every new Bazel binary version, since the implicit dependencies can be different
for every Bazel release.
The section below describes the steps to prepare distribution directory using
Apollo-provided tarballs.
## Prepare Distribution Directory using Apollo-provided tarballs
1. Check Bazel version used by Apollo by running `bazel version` from inside
