Jar works on double-click, but not in command line

Following up on one of my questions in another post.

I added the maven-assembly-plugin to my POM, and now the jar works, but only if I double-click on the jar in the file system. If I try to run the jar from the command line, I still receive this error:

Exception in thread "main" java.lang.NoClassDefFoundError:

This concerns me, because it seems like this jar is not platform-independent. How can I fix this?

That should not happen as launching it through command line is the exact same as launching by double click. Maybe you are trying to get it to use a different version of java through command line and that is what isn't working? to clarify, the command to launch a jar is java -jar name.jar

How do you launch it?

You need to use the -jar switch:

java -jar your_jarfile.jar
