Pact Foundation

Hey folks.
Im facing a weird error when I try to verify my grpc-contract in the provider side:

```Plugin protobuf failed to validate the interaction: Plugin configuration item with key '330d8b9b2fef4480c366dd95e2ebb56e' is required. Received config ["f58d69682eec609d725e46c388aff650"]
io.pact.plugins.jvm.core.PactPluginValidationForInteractionException: Plugin protobuf failed to validate the interaction: Plugin configuration item with key '330d8b9b2fef4480c366dd95e2ebb56e' is required. Received config ["f58d69682eec609d725e46c388aff650"]```
Do you all know what about this error?

Thanks guys.

Do a clean before running your consumer tests, you probably have a stale Pact file affecting things

Yes, I cleaned,,, and also removed.

My service is generating one contract that uses different proto files, I think that it can be the problem.

Pact is always generating only one of this files in the configurations:

Example:

```"plugins": [
      {
        "configuration": {
          "bd82122dd37a0a29e676d1f63ef62eba": {
            "protoDescriptors": "",
            "protoFile": ""
          }
        },
        "name": "protobuf",
        "version": "0.3.4"
      }
    ]```
