I'm trying to create an executable .jar from a maven project using eclipse mars. The project itself can be found on https://github.com/jsprit/jsprit
So far I have successfully imported jsprit to eclipse as a maven project and I am able to run examples as Java Application.
I haven't yet been very successful at exporting it as an executable jar. Let's say I want to export SimpleExample.java. I have created the .jar but if I try to run jsprit-examples-1.6.2-SNAPSHOT-jar-with-dependencies.jar I get the following error message:
Error: Could not find or load main class jsprit.examples.SimpleExample
The pom.xml which is located under jsprit-examples is following:

Everything else is as same as in the github repository. I ran 'Maven Build...' on jsprit-examples. Under 'Edit Configuration->Goals' I did 'clean package assembly:single'.
This is my first experience with a maven build so it might be a very simple problem to someone who has some experience with maven.
Thanks!
I you want to put all the dependencies in one executable jar, you need to create an uber-jar. I usually do this with the maven shade plugin .
