custom liveaction implementation using BaseAction and BaseActionFactory

Hi,

I am trying to implement custom liveaction as per the steps mentioned in http://suryakand-shinde.blogspot.com/2015/01/custom-synchronisation-or-rollout.html article. when i run mvn, build fails miserably with following exception. i've referred some of forum discussion but not much useful in resolving this aspect. any pointers will be really helpful
