Mounted resource in jar file

GAteway hooks have a method called getMountedResourceFolder, which mounts a folder from a module's gateway jar file. I'm following the gradle tutorial for creating a module. How do i add a resources folder to my project that'll get included in the gateway jar in the module?

Standard layout would be a src/main/resources folder next to your src/main/java folder.

does that automatically get copied over, or do i have to modify the build script?

Anything in src/main/resources should be automatically included in the jar file.
