Hmm, you might want to restart your machine. It can not find the main epubcheck routine in that jar for some reason.
Once restarted, open a terminal and launch the epubcheck.jar from the command line as described on the official epubcheck website and see what if any errors it produces.
Once you get it working from the command line, we should be able to get it working from the plugin since the plugin uses a sub process from the command line to handle things just in python.
