no such package '@protobuf//': java.io.IOException: Error downloading ... Checksum was XXX but wanted YYY

Description of the problem / feature request / question:

Whole day “bazel build” command fails. From logs I see that it compares check sum ‘@protobuf//’ and they do not match. I’ve tried it on several machines - had same error.

If possible, provide a minimal example to reproduce the problem:

git clone https://github.com/tensorflow/tensorflow.git cd tensorflow ./configure bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package

Environment info

• Operating System: Ubuntu 16.04

• Bazel version (output of bazel info release): release 0.5.2 (also tried 0.5.3, 0.5.4 - had same result)

Anything else, information or logs or outputs that would be helpful?

Hey – take a look at https://github.com/tensorflow/tensorflow/issues/12979 … it seems GitHub changed the way they compress archives and invalidated all the existing checksums. 😦

@nkjassal I am not sure why your protobuf.bzl is giving you an error. Double check the path to the archive. Mine ended up being something like this.

tf_local_repository(
        name = "protobuf_archive",
        path = "C:/bazel/repos/protobuf-3.6.0",
    )

    # We need to import the protobuf library under the names com_google_protobuf
    # and com_google_protobuf_cc to enable proto_library support in bazel.
    # Unfortunately there is no way to alias http_archives at the moment.
    tf_local_repository(
        name = "com_google_protobuf",
		path = "C:/bazel/repos/protobuf-3.6.0",
    )

The path should point to the directory of the BUILD file. Let me know if you are still having issues.
