I am trying to configure hibernate orm mapping tool to my java class and using MySQL.When I tried to run the application, I have encountered error on my console logs as Error java.lang.ClassNotFoundException: play.db.jpa.JPABaseStatement. The hibernate version that I am using right now is version 5.4.10.
This is the error log
