# How to check that all mirror URLs work:
|
|
|
|
# 1. clean $HOME/.cache/bazel
|
|
|
|
# 2. bazel clean --expunge
|
|
|
|
# 3. bazel sync (failed downloads will print warnings)
|
|
|
|
|
|
|
|
# A specific link can be upload manually by running e.g.
|
|
|
|
# upload "github.com/google/boringssl/archive/1c2769383f027befac5b75b6cedd25daf3bf4dcf.tar.gz"
