no such package '@com_google_protobuf//'

I have tried to build an overlord: $ bazel build //go/overlord/runner then, I got the ERROR:

ERROR: /home/user/goworkspace/src/github.com/google/minions/src/proto/overlord/BUILD.bazel:4:1: every rule of type proto_library implicitly depends upon the target '@com_google_protobuf//:protoc', but this target could not be found because of: no such package '@com_google_protobuf//': java.io.IOException: thread interrupted

I'm struggling to repro this issue. I'm starting from a clean git clone, clean bazel, and then building the target you mention. Everything builds correctly. It's also puzzling that the target that is failing for you is also built just fine by Travis.

Can you tell me a bit more about your setup to help me reproduce please? Local changes if any and version of bazel would be a starting point, I guess (though I'm no Bazel debugging expert). Can you build any other target successfully?

I use Ubuntu, I have updated Bazel with Build label: 0.16.0. $ bazel build -s //go/overlord/runner

Ok, I'm running 0.15.2 locally so updating to debug further. However, there is a fairly clear error on cloning the googleapis repo. Can you successfully clone https://github.com/googleapis/googleapis from the command line from your box? (I can't begin to imagine why that would even fail, but let's have a look at that too just in case)

[MohamedElqdusy]

I have tried to do so $ go get github.com/googleapis/googleapis

# cd .; git clone https://github.com/googleapis/googleapis /home/user/goworkspace/src/github.com/googleapis/googleapis
Cloning into '/home/user/goworkspace/src/github.com/googleapis/googleapis'...

Ok we're getting somewhere. I've confirmed everything works with bazel 0.16.0, with a clean build, over the slow ADSL I'm using here.

The error you are seeing is not related to minions or bazel: it seems to be either on your network or in the base system, given it reproes with native git. Given you have cloned minions I assume you can clone git repos, so that seems to rule out a config issue. The googleapis repo, is really really big. So it's possible that your network connection is not that stable and you are seeing it die midway through. Can you see it running for a while or does it error out immediately?

At this point we're trying to debug your network + your OS which seems not like something I can really help with :-/ Looking online though I read that git config --global http.postBuffer 1048576000 might help in these cases [https://stackoverflow.com/questions/6842687/the-remote-end-hung-up-unexpectedly-while-git-cloning]

I'm happy to help further with the build process but I'm not sure I can be of use in this specific instance.
