I am learning MRJar and trying to create a sample example which has folder structure as follow, both java folder and java9 folder are marked as source root

└───main
    ├───java
    │   └───com
    │       └───test
    │               App.java
    │               DefaultVersion.java
    │
    ├───java9
    │   └───com
    │       └───test
    │               DefaultVersion.java
    │
    └───resources

IDEA complaining about duplicate class which is expected as it has duplicate classes under source root. But is there a way to config IDEA to support MRJar development? Thanks.

It is not supported at the moment. Please vote for this request: IDEA-168946 Add support for building Java 9 multi-release jars.
