Ran into this -- [INFO] [remote-resources:process {execution: default}] [ERROR] Error loading supplemental data models: Could not find resource 'supplemental-models.xml'. org.codehaus.plexus.resource.loader.ResourceNotFoundException: Could not find resource 'supplemental-models.xml'.
I know we solved this by adding a file, src/main/appended-resources/supplemental-models.xml. I guess it just needs to be packaged. I'll look at that -- Isabel you might know more about this.
