This needs to be set to the same version, otherwise maven won't be able to find the generated `protobuf-java-3.3.1.jar` and will produce `package com.google.protobuf.GeneratedMessageV3 does not exist` errors. I'm not familiar with maven so not sure if this can be resolved without restricting the dependency.

The Python unit test works fine without changing the protobuf version dependency FYI.
