This is a grab-bag for any time Kokoro fails during downloading resources or similar. We cache dependency downloads on our other CIs, so such problems should be more rare. This issue should only be for flakes where caches on Travis CI or Jenkins would have been able to circumvent the failure.

Would switching to a google operated mirror help a little with the connection flakiness?

If the mirror is near GCP, maybe. To me the problem is assuming that networks and services are 100% reliable. But maybe swapping the mirror improves the situation even if it doesn't fix the problem.

Multiple errors in the form:

Although these are obviously misconfigurations of maven.org, this type of failure would have been less likely if we weren't doing I/O during the build.

kokoro: Use --include-build in cronet
7a67285 
This avoids needing to build all of grpc as well as avoids having to
manually track which dependencies are necessary.

This cuts 1.5 minutes off the Cronet build time (to 3.5 minutes). But it
also reduces the amount being downloaded which should help with grpc#3284.
