Intellij IDEA 15 with grails 1/2 when do the change on controller and service runtime can not recompile

Hi I got this issue only in Intellij 15. 14 is working.
The error is :

- 1: $getStaticMetaClass() in com.gateway.report.LoanApplicationController cannot override $getStaticMetaClass in com.gateway.report.BaseController; attempting to assign weaker access privileges; was public

@ line -1, column -1.
1 error

Process finished with exit code 1

When I delete all the plugins sync grails and reinstall (clean) then rerun will solve the problem.

Start by reproducing the runtime recompilation failure in IntelliJ IDEA 15 with Grails 1/2, using the controller and service changes described, and compare the behavior with IntelliJ IDEA 14. Inspect the Grails IntelliJ plugin's recompilation path; done means those changes recompile without the $getStaticMetaClass access error or a clean reinstall workaround.
