Your description is not very detailed,so i don’t know how to help you.
But I know that,first you should delete the “**hazelcast” **plugin,becuse it conflict with the clustering package.
Second ,you project lose coherence.jar、coherence-work.jar、tangosol.jar three jar,you should download them from oracle and add your build path
Third, you should fix the bugs int the package of “org.jivesoftware.openfire.sip.tester”,you find SipCommRouter.java and SipManager.java ,
fix the problem by yourself , or use eclipse autoFix tool. Probably the tow classes not implement Abstract class or not catch Exception.
