Github user aljoscha commented on the issue: https://github.com/apache/flink/pull/3567 AFAIK it's not possible to make IntelliJ pick up the checkstyle config by itself. On my machine the setting is in the "*.iml" project file and I think we have so far not included IDE specific project files because this is quite uncommon, I think. @dawidwys I'll create a new maven module to host the maven-build related files. This will make it easier to include it in different modules without dealing with paths in the checkstyle config.
