A question for debugging bazel internals

[Yunlong Liu]

Hi, 

We met a problem that sometime the `repository_ctx.download` won't hit the repository cache for downloading the external repository when we put our code repo on NFS.

I think it might relate to the NFS itself but just in case that we can fully understand this issue, I am wondering how I can get the log from the bazel library:

https://cs.opensource.google/bazel/bazel/+/master:src/main/java/com/google/devtools/build/lib/bazel/repository/downloader/DownloadManager.java;l=81?q=DownloadManager&ss=bazel%2Fbazel

Thank you!

I don't think Bazel generates a log for repo cache hits, but it's definitely possible to add one.
Maybe file a github issue as feature request or even a PR?
