Java (9+) Module + Groovy Compile failure

I am creating a JAVA project using JAVA 9+ Modules that also have Groovy classes in it; Gradle manage to compile Groovy classes and Java classes and package them all in the resulting modular JAR.

When I try to compile the project using IntelliJ I get the error:

Error:(1, 1) java: file should be on source path, or on patch path for module

I get the same error when I try to compile the module-info.java file using the groovy compiler (found this out in one of the many gradle configuration tries).

Is there a way to configure IntelliJ so it only compiles .groovy files with the Groovy compiler?

Next is an image with a test project structure and the resulting error.

Thanks in advance for any guidance.
