How to add module to Play! Framework 2.4

I'm trying to separate some application logic into modules. I've created module which is supposed to handle users (view profile etc. (models + controllers))

I've added module into reference.conf

play.modules.enabled += "modules.users"

But when I try to access app:

Module [modules.users] cannot be instantiated.

Is creating Custom loader only option?

This syntax works only with runtime dependency injection: the configuration is read at runtime, and the required modules are loaded.

The module "name" must reference a Guice Module, where you define your custom bindings.

One full example:

conf/application.conf

play.modules.enabled += "auth.di.AuthModule"

modules/auth/app/di/AuthModule.scala

package auth.di

class AuthModule extends AbstractModule {

   def configure() = {
       // Binds your services here
   }
}

build.sbt

lazy val root = (project in file("."))
  .enablePlugins(PlayScala)
  .dependsOn(moduleAuth).aggregate(moduleAuth)

lazy val moduleAuth = (project in file("modules/auth"))
   .enablePlugins(PlayScala)

Tips: Use scala-guice to define your modules more fluently.
