intellij-idea - Building small jars with kotlin

Question

My jar files become huge, when I remove libraries from output the jar doesn't run.

These are my steps:

1. file -> project structure
2. add jar -> from modules with dependencies
3. select main class

Now, if I keep all extracted jars (libgdx, junit and kotlin) the jar file becomes too large. If I remove them all the jar won't run.

How do I know what to remove and what to keep?
