Protocol Buffers source is missing files

问题

For background, see: How to compile google-fhir proto files

There seem to be missing .java files when compiling using protoc. I do not see those files here: https://github.com/google/protobuf/tree/master/java/core/src/main/java/com/google/protobuf either. Of course, protoc generated additional files such a Patient.java that were not in the linked folder above. I just need it to compile.

UPDATE

Running examples/protogen/generate-proto.sh returns:

FAILED: Build did NOT complete successfully
generate-descriptors.sh: line 29: ../../bazel-bin/java/ProtoGenerator: No such file or directory

It looks like bazel did not get run correctly, because ProtoGenerator is not in hazel-bin. I ran bazel build, in the root directory where there is a BUILD file. It complained about a workspace, to which I was told to create an empty WORKSPACE file. When done, there were no errors and bazel-bin was created. Are there additional parameters than bazel build. Also, I thought I saw more than one BUILD file in addition to the one in proto/stu3, but maybe I am mistaken.
