Java – Marvin: “NoClassDefFoundError: com/jogamp/newt/event/KeyListener”

I’m trying to use external jar JOGL and GlueGen in my Maven project. The build process works, but when I execute the jar I get this error message:

I also tried building jars with shaded plugins and installing JOGL and GlueGen in a local repository, with the same result.

Thanks a lot for helping with this!

Maven does not package dependent classes into the final .jar. Some options:

• Use the -classpath flag ( How to run a java class with a jar in the classpath? Manually add dependencies to your classpath.
• Use the Maven exec plugin to generate the correct classpath ( How do I execute a program using Maven? )。

Create a “

• fat” jar with all dependencies (Maven build assembly with dependencies)。
