Protobuf: Add a BUILD rule for building the JavaLite proto runtime (similar to "protobuf_java")

[cgrushko]

(this is required for using Bazel's java_lite_proto_library)

[cgrushko]

@xfxyjwf more and more people are asking about JavaLite support; do you have an estimate for when protobuf team is going to work on this, if at all?

[thaidn]

I really need JavaLite support because our open source project needs to run on Android.

[blerest]

Do you have any news regarding javalite support?

[xfxyjwf]

@cgrushko If we add a java_library rule for lite runtime in javalite branch, is it sufficient for java_lite_proto_library to work?

[xfxyjwf]

java_lite_proto_library should be working after https://github.com/google/protobuf/pull/3288

I have put up a working example here:
https://github.com/xfxyjwf/bazel_proto_examples

[xfxyjwf]

Fixed in https://github.com/google/protobuf/pull/3288

A working example can be found in: https://github.com/xfxyjwf/bazel_proto_examples/blob/master/WORKSPACE

Neither of those links works, and the "lite" option is still broken in protoc 3.7.2.

Am I missing something? Thanks.
