I want to include a subproject dependency (Core) in the shadow JAR of another subproject (App). The Core project just contains some classes used in the App project and a plain text file named TEST with some example text in it. The resulting Core JAR includes the original compiled classes and the TEST file correctly.
Now if I include the Core dependency in the App project without any relocation it copies the classes and resources correctly to the resulting shadow JAR, but if I relocate the core package to a package within the app package then the resources of the Core project are not included in the resulting JAR file (the TEST file is missing).

I don't know exactly how to explain the complete project structure so it's probably better if you take a look at the test project yourself: https://github.com/Minecrell/GradleTest

So basicly when I use relocation then the resources of the project dependency are not copied to the resulting JAR.
