Assets is already defined as object Assets

Question

I am doing more extended tests for Play Subproject feature as described here: http://www.playframework.com/documentation/2.0/SBTSubProjects. But I am getting the error:

Answer 1

It is a known bug: https://groups.google.com/forum/#!msg/play-framework/2Zk5wjAlIng/Jcec1lt7AzQJ

My workaround for an own admin module:

package controllers.admin;
import controllers.AssetsBuilder;
import play.api.mvc.AnyContent;
import play.api.mvc.Action;
import play.mvc.*;

public class Application extends Controller {

    private static AssetsBuilder delegate = new AssetsBuilder();

    public static Action<AnyContent> asset(String path, String file) {
        return delegate.at(path, file);
    }

}

//routes file
GET /assets/*file   controllers.admin.Application.asset(path="/public", file)

Answer 2

I faced this problem last week when I was trying to write the Assets class as a Java class. I could solve the compilation problem writing the Assets class in my submodule as a Scala class, the same way as described on the docs: http://www.playframework.com/documentation/2.1.1/SBTSubProjects

Basically, my project's structure is:

MyApplication
  | - app
  | - conf
  | - modules
        | - admin
            | - app
                | - controllers
                    | - admin
                        | - Assets.scala
  | - project
  | - public

Assets.scala content:

package controllers.contabil

object Assets extends controllers.AssetsBuilder 

And finally, the content of my admin.routes file is:

GET     /assets/*file    controllers.admin.Assets.at(path="/public", file)

# Home page
GET     /index           controllers.admin.Application.index() 

Cheers
