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've had the same issue (although project structure was as in all examples and documenctations and routes files were in the right places) - sub-projects routes file haven't been placed into the main target/scala-2.11/routes and couldn't be find

I solved it by adding unmanagedResourceDirectories in Compile += baseDirectory.value / "<path_to_project>/conf at the end of build.sbt:

....
lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)
  .settings(commonSettings: _*)
  .aggregate(core, providers, zms, api)
  .dependsOn(core, providers, zms, api)

lazy val core = (project in file("apps/core")).enablePlugins(PlayJava, PlayEbean)
  .settings(commonSettings: _*)
  .settings(
    name := "core"
  )

lazy val zms = (project in file("apps/zms")).enablePlugins(PlayJava, PlayEbean)
  .settings(commonSettings: _*)
  .settings(
    name := "zms"
  )
  .dependsOn(core)

lazy val api = (project in file("apps/api")).enablePlugins(PlayJava, PlayEbean)
  .settings(commonSettings: _*)
  .settings(
    name := "api"
  )
  .dependsOn(core)


//Here are the lines that solved the problem
unmanagedResourceDirectories in Compile += baseDirectory.value / "apps/core/conf"
unmanagedResourceDirectories in Compile += baseDirectory.value / "apps/zms/conf"
unmanagedResourceDirectories in Compile += baseDirectory.value / "apps/api/conf"

fork in Compile := true

It will say sbt to add files under sub-project conf directory to be included in the main project classpath

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.

well, this is really silly. I figured my problem was not with the Play Framework, but confusion with Intellij IDEA's red highlighting on sub.Routes. With your template, I figured this was the case. I run the project and it works just fine. I just have to ignore the red text highlighted by IntelliJ on that part. Thanks btw. – Cipher Hat Oct 05 '14 at 02:15
