So, we are using Apache Flink's pyflink. We build some custom components using the flink java api that we need to make available to python. That jar is loaded locally by the client using py4j and is uploaded to the flink cluster when deploying jobs. Until now, we were building the jar and copying it into a lib dir within our python source tree. We created a resources target which includes the jar. I wasn't sure if there was a way to update the resources target to point to the jar that the package goal creates from a deploy_jar target.
