Play Framework 2.3.4 routes redirection to subproject

Question

quite new with Play framework, but I tried to setup subproject for my main project but when I tried to redirect the route from the main project to subproject, it couldnt recognise the subproject variable. I have followed based on the documentation here PlaySubProject

My main project structure is as illustrated below:

Main
   app
   conf
      application.conf
      routes
   modules
      sub
         app
         conf
            sub.routes
         build.sbt
   logs
   project
   public
   target
   test
   activator
   activator-launch-1.2.10.jar
   build.sbt

This is my main build.sbt file:

name := """Main"""

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayJava).aggregate(sub).dependsOn(sub)

lazy val sub = (project in file("modules/sub")).enablePlugins(PlayJava)

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  javaJdbc,
  javaEbean,
  cache,
  javaWs
)

and my subproject build.sbt is as follows:

name := """Subproject"""

version := "1.0-SNAPSHOT"

scalaVersion := "2.11.1"

libraryDependencies ++= Seq(
  javaJdbc,
  javaEbean,
  cache,
  javaWs
)

Finally, this is my main routes file.

# Routes
# This file defines all application routes (Higher priority routes first)
# ~~~~

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

# Map static resources from the /public folder to the /assets URL path
GET        /assets/*file        controllers.Assets.at(path="/public", file)

# SUB's
->  /sub    sub.Routes

The problem is in this routes file, it cannot even recognize sub variable on the last line at sub.Routes. How to solve this problem?

I'm not sure about your specific issue, but I setup a fully working and reasonably well-documented multi-project example at https://github.com/josh-padnick/play-multiproject-template. This is based on Play 2.2.3 (not 2.3.x), but it should be pretty close to what you need.
