Nick Boldt commented on JBDS-4154:
----------------------------------

0. install rpm from

2. Ignore the singleton errors in the log - they'll go away when we move this version of m2e into the devstudio TP and therefore the RPM, too.

{code}  Another singleton bundle selected: osgi.identity; osgi.identity="org.eclipse.m2e.refactoring"; type="osgi.bundle"; version:Version="1.7.1.20161104-1805"; singleton:="true"
{code}

3. Central > Java EE Web project > ignore JAX-RS error (JBDS-4133)
4. select project folder > right-click > run as > maven build... > set goals = clean install

5. FIXED!
