Service not generated at all for Go

[J7mbo]

Hi! I'm running the following from StackOverflow (but also from reading the docs here):

docker run --rm -u $$(id -u) -v${PWD}/src/api:/source \
	-v${PWD}/src/api:/output \
	-w/source jaegertracing/protobuf \
	--go_out=/output \
	--go_opt=paths=source_relative \
	--go-grpc_out=/output \
	--go-grpc_opt=paths=source_relative \
	--proto_path=/source \
	-I/usr/include/google/protobuf /source/*.proto

Expectation
This should generate two files, one of them being the service.

Problem
This generates a single file for my protobuf file, but there's no service generated.

Extra info
I can't use --plugins=grpc anywhere, because it says "--plugins is not supported", so I guess that's why the service isn't being generated.

Is there something I'm missing here? If it doesn't support grpc for Go then there's not much point of listing it as an option? Is it just not possible to generate a Go grpc service with this container and so another solution is needed?

it works fine in jaeger-idl repo
