jprotoc doesn't support proto3 files #151

Closed pmlopes closed 3 years ago

pmlopes commented 3 years ago

When using proto3 files you get an error:

test_proto3_optional_helloworld` is a proto3 file that contains optional fields, but code generator protoc-gen-grpc_java hasn't been updated to support optional fields in proto3. Please ask the owner of this code generator to support proto3 optional.

For example reproducer see:

Closing as this was a issue with misaligned protoc + protobuf versions
