Yang Viewer NoClassDefFoundError

[ds2286s]

I have built the yangviewer-project.
But it seems like there is missing a class in the repository.
I can build the jar with the pom.xml

But when i run "java -jar yang-viewer-1.0.0-SNAPSHOT-jar-with-dependencies.jar" it fails.

Exception in thread "main" java.lang.NoClassDefFoundError: org/opendaylight/yang

Solved it. I need to add the dependent jars to the classpath
