Old descriptor.proto

[rfevang]

The descriptor.proto bundled is pretty old, and lacks options used in the built-in proto3 types (cc_enable_arenas, csharp_namespace, go_package and objc_class_prefix). The result is an annoying list of errors found if one uses any of these protos. Any chance of updating this file?

As a side note, I can't figure out how to specify my own descriptor.proto file. It's not clear what the options field is relative to (the default just says google/protobuf/descriptor.proto, where is that google folder located?). Nothing I've done seems to make a difference, whether I put in an absolute path, one relative to my home directory or absolute gibberish. It still figures out that java_package is a valid option, but not that go_package is one.

I am also having issues with this. I have made sure to add the path to "my own" google/protobuf/descriptor.proto in project settings -> Protocol Buffer -> Import Paths, which does not work. Specifying an absolute path does not help either.

I also added an import path, and see it being picked up in the xtext output:

[Worker-12] indexing platform:/resource/mirror/build/extracted-include-protos/main/google/protobuf/descriptor.proto

But it's also picking up the packaged descriptor, and seems to be preferring that:

[Worker-12] indexing platform:/resource/com.google.protobuf/google/protobuf/descriptor.proto

E.g. I still have errors due to go_package, cc_enable_arenas, etc.

At this point I think I'll have to uninstall the protobuf-dt plugin, as I don't see anyway to resolve/ignore these errors.

I have this error as well. It upset me very much.
