Game Wedding 2

Has anyone tried swagger with game 2. I have 2 java projects game and I am trying to combine knickknacks with it. I installed the package using this dependency:

"com.wordnik" %% "swagger-play2" % "1.3.7" 

      

        
        
        
      

    

but I keep getting this error from the routes file:

object ApiHelpController is not a member of package controllers
In C:\play project\check8s-api\conf\routes at line 21.

line 21: GET      /api-docs.json                controllers.ApiHelpController.getResources

      

        
        
        
      

    

any idea how to fix this problem?
