The CI build for my Bazel C++ project recently broke. The error indicates that the HTTPS download for a http_repository failed:

How can I delete Bazel's cached copy of the .tar.gz file so that I can test whether the download succeeds locally? I've tried bazel clean --expunge but it does not seem to delete downloaded artifacts.

rm -r $(bazel info repository_cache) is the brute force solution. Passing --repository_cache= to commands should also disable it.
There's more about the repository cache in the documentation.
