As I'm quite new to both kotlin and IntelliJ IDEA, it would be very hard for me to solve this issue on my own.

Notice, that my DBO classes are getting enhanced with the help of IDEA plugin for ebean, but as it comes to generating finders and query-beans, I am struck as none of samples provided for ebean+gradle+kotlin works for me.
