This is somewhat of a rough cut, since it doesn't split apart the lite and full targets, or unit tests. However, it does split sources under src/google/protobuf into a separate package, which is a fairly impactful change.
This avoids conflicting names in a couple of cases.
1. Within google, we want to sync files but not name them BUILD (since the structure doesn't match).
2. On case-insensitive filesystems, `build` may be used for a build directory. Naming `BUILD.bazel` avoids potentioal conflicts.
This change adds `rules_pkg`-based targets that will produce source distribution archives, similar to `make dist`.
These rules produce nearly the same outputs as `make dist`. However, there are some differences and caveats:
1. The outputs do not contain vendored googletest sources.
2. You have to run `autogen.sh` before `blaze build pkg:all`. This produces several autotools-related files directly into the source tree.
3. The output .zip files do not have a directory prefix like `protobuf-3.20.1-rc-1` (this will be addressed after [Substitute package variables in `pkg_zip#package_dir`. bazelbuild/rules_pkg#577](https://github.com/bazelbuild/rules_pkg/pull/577); the tar files do have this prefix, though.)
4. One file is missing from the archives, which is produced during the `make` build: benchmarks/gogo/cpp_no_group/cpp_benchmark.cc
5. In several places, I have explicitly excluded some files that are not in the autotools distribution outputs. I think most of those files should probably be included, but for now, I'm aiming for parity with `make dist`. These are marked with comments, so it should be easy to clean them up later.
* Protobuf Java/Core Tests running w/ Bazel.
Also integrates rules_jvm_external and migrates existing maven deps
in place.
* Add test_suite target that maps to rule name.
* Lite tests passing in Bazel
* util tests passing with Bazel.
* Add conformance and build testing to //java:core
* Cleanup bzl style and lock down access to failure lists.
* Adding Java Lite conformance tests.
* rm newline
* parameterize conformance_test
This makes usage of failure lists more explicit.
* restrict visibility more for newly added libs and fix formatting.
* fix formatting and visibility.
* move testing.bzl to an internal package.
* fix file formatting.
* moving conformance_test to internal.bzl
