Thank you for your assistance.
Your friendly error-reports-inbox.

Comment 1 Andreas Sewe CLA 2015-07-21 03:42:07 EDT 
As far as I can see, this can online happen if ModelRepository.system is null, i.e., if DefaultServiceLocator.getService(RepositorySystem.class) returned null.

This should never happen if the Aether bundles are present.

Dear original reporter, can you please open the Console view, select the Host OSGi Console and enter the following commands and paste their outputs here:

  ss org.eclipse.aether
  b org.eclipse.recommenders.models

Thank you.
