Pants

so I just added
```
    @classmethod
    def prepare(cls, options, round_manager):
        super(ScalaPBGen, cls).prepare(options, round_manager)
        round_manager.require_data(JarImportProducts)
```
but it does not seem to fix it

solved ! comparing with java_protobuf_library, the problem was in the target ! I needed to uses `imports` instead of `dependencies`

did you find that by checking the code? i can see `imports` in that target's source file but it seems like this would be hard to figure out without documentation?

yeah I compared my code with the working example and looked out for the differences
