repository.getExtent error for all other than maven build

No matter what method you use to build example-modle or example-summit-webapp from inside Eclipse an error occurs. Using mevenide to launch it from within Eclispe works, but does not allow debug. I have tried a JUnit test and a straight class with main. Each one gets the following exception.

If I run 'maven' from dos command line it works, the only problem is that I cannot debug anything. Be interested to know if this is the same on IDEA. Here is the exception

here is the code in the JUnit test setup()

String filename = "example-summit-webapp/src/uml/SummitTestModel.xml.zip";
RepositoryReader rr = null;
try

catch (MalformedURLException e)

JMICapableMetadataProvider mp = new JMIUMLMetadataProvider(rr);

I cannot fix my plugins until I can debug. Things have thus ground to a halt again. Ideas?
