Hi, When building a scala/java project using mvn package and running the jar, i'm getting the following error "Exception in thread "main" java.lang.NoClassDefFoundError" for a java dependency.

How do I rectify this?

I've attached the build portion of my pom.xml

Can you push the log/stacktrace of the exception ?

I also suggest you to update the version of the plugin: maven-compiler-plugin

Thanks david, I apologize about the double post as the google groups confused me a bit about the lack of emails (I just realized auto subscribe to updates is defaulted to off). 
Updating the version fixed the error.

Your help and promptness was amazing and I sincerely thank you for that.
