Play2.5 Migration || java.lang.VerifyError: Cannot inherit from final class

[pri...@cashcare.in]

I have tried deleting .ivy folder cleaning of lib folder, however none of it helped. Clearly its issue with the dependancy, I am still not sure which of this file is causing the issue.

As understood and applied.

Prefer a clean slate approach for such a migration.

Delete .ivy/,sbt/.m2 folders if any.

Delete lib (one of the main culprits)

in build.sbt and plugins ensure that all the dependencies are compatible with the latest play major version.

Clean compile and hope that you dont have to storm into any of such exceptions.
