junit 19.0.2.5 UnsupportedClassVersionError - Mac OS X

I've been struggling with this. If I run junit to the same files from a shell I can get it to work but from Slick Edit I'm always getting this error. Has anyone run into this?

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/junit/runner/JUnitCore : Unsupported major.minor version 52.0

I've been playing with the source and target arguments in Java Options but haven't gotten it to work.

This probably means that the vsjunit.jar that comes with SE has been built with a newer version of Java than what you are using for your project.

You can recompile the vsjunit jar with your JDK to build a compatible version, the source code is in vsjunit of your SE installation.  Better yet, upgrade your project to Java 8 if at all possible.

Thanks - fixed!
