I tried to study about it , in some places it asked to delete the cache files from the project I did the same. Deleted the cache files except no-cache. deleted the classes created in project on complie.
On Compiling the project its taking only 1 permutation.
Totally, unaware of the problem that whats the problem in adding the jar files in lib folder. As, its clear we cant host the project without adding the jars in lib. So what is the solution.
REMOVED THE gwt-dev.jar from the lib and it worked totally fine. Something i was totally unaware of it could also create problem.
