Other module trees do not have kafka's dependency, so I don't post it. thanks. 在 2018/12/18 上午10:42, Liam Clarke 写道: Can you please post the full output of maven dependency:tree from the parent POM in both scenarios?

But when we move this dependency to project's parent pom file, the dependency "kafka_2.11" version is changed automatically. Why? You can see Kafka_2.11 version is changed to 1.0.2? It's so strange, in out project we DO NOT dependency this jar in other places.
