bazel: Bazel failed to build behind proxy

Description of the problem / feature request:

I would like to follow tensorflow example to build generate_streaming_test_wav to generate test wav. The Bazel version on my machine is 0.16.1.

The problem is when I use the command bazel run tensorflow/examples/speech_commands:generate_streaming_test_wav , the following error message shown up:

xxx@xxx:~/kws/tensorflow-0911$ bazel run tensorflow/examples/speech_commands:generate_streaming_test_wav
Starting local Bazel server and connecting to it...

However, I can use wget and curl to download those two packages. 1.https://mirror.bazel.build/github.com/bazelbuild/rules_closure/archive/dbb96841cc0a5fb2664c37822803b06dab20c7d1.tar.gz 2.https://github.com/bazelbuild/rules_closure/archive/dbb96841cc0a5fb2664c37822803b06dab20c7d1.tar.gz Since the file is able to be downloaded on my machine, I think the proxy settings are fine.

A workable workaround method is change the http_archive to local_repository. However, the build process still stopped because tensorflow apply their rule (tf_http_archive) to fetch other files in the following step. It’s not reasonable to download all the file manually and replace all the `tf_http_archive’ in each file.
