Hi Robert, thanks for your hints. I was not sure whether I was building a proper fat jar, as I have not used the Flink Archetype for my project. However, I have set up a sample project at
https://github.com/robert-schmidtke/flink-test/ which is nothing more than the Quickstart Archetype plus the instructions to bundle the Kafka dependencies. The resulting jars (mvn clean package -Pbuild-jar and mvn clean package) do not contain the org/apache/kafka/** classes. Can you have a quick look at the pom? However, as I said, it's verbatim Archetype+Flink Docs. Thanks a lot in advance!
