How do I export Maven Libraries together with my program?

Question

I've created a Discord bot in Eclipse and want to export it (Jar file). The problem is: I can't run it. Each time I try to start it it gives me this error: java.lang.NoClassDefFoundError: net/dv8tion/jda/core/entities/Game

I'm using "JRE System Library [JavaSE-1.8]" for my program.

This here is my pom.xml file https://pastebin.com/bcs51jm9

After some research it seems like Eclipse doesn't implement the Maven Librarys into the Jar-file.
How can I fix this?

Exporting a jar with Eclipse from the wizard is generally the way when you don't have a build tool that allows to do it in a straight way.
You use Maven. So you have this tool.

What you need is configuring your pom.xml to enable the assembly plugin execution with the jar-with-dependencies descriptorRef.
It allows to specify the main class and to create a fat jar that contains all required dependencies at runtime according to the Maven dependencies declaration defined in your pom.

By executing mvn assembly:single you could so generate an additional jar : a jar-with-dependencies .
