[Building Sakai] Getting NullPointerException testing source build of 2.7.1

Chris,

I got the same error.  Is there something else I need to do besides run the
mvn command?

Just to make sure we¹re on the same page with regard to the change.  I
changed line 3196 of PresentationManagerImpl.java.  Here is a snippet that
includes 3196 (in bold):

         try {
            resource = getContentHosting().addResource(name, folder, 1,
type,
                                                       bos.toByteArray(),
resourceProperties, NotificationService.NOTI_NONE);
         }
         catch (Exception e) {
            // unexpected error: tried to add new resource and failed
            logger.warn("createResource(addResource): "+e);
         }
      }
      
      String uuid = getContentHosting().getUuid(resource.getId());
      return getIdManager().getId(uuid);
   }
   
   /**
    * 
    * @param portfolios A list of Presentation objects
    */
   protected void convertPortfolios(List portfolios) {
      org.sakaiproject.tool.api.Session sakaiSession =
SessionManager.getCurrentSession();


And here is the top of the stack trace.  It looks pretty much like the one I
was getting before:

org.sakaiproject.portal.api.PortalHandlerException:

Should I delete and recreate the maven repository and install a fresh copy
of Tomcat and then do a fresh install of Sakai?

Thanks,
Rob
