Run the maven grouper-parent clean and install (you can right click in eclipse on the pom and run as: maven clean, then install). you might need to delete .m2/repository/* if it is corrupt. You might need to bump up memory to 512MB to get maven to build

If there are problems in a project, you might need to right click, and do Maven → Update project When you do that, the first time, check the box to update project configuration. In all subsequent times, do NOT have the box checked to update project configuration from pom, or your settings will get undone 
All the projects should now be open and compiled.

This is one of the main tricks. In my eclipse, the "conf" dir is excluded due to the pom.xml in maven
 Image Modified
Link the conf dir (even though its already a source folder) in java build path - ${PROJECT_LOC}/conf → GROUPER_CLIENT_CONF
