Play Framework For Scala: Erreur de compilation [type Application n'est pas membre des contrôleurs de package]

J'essaie de compiler un exemple de scala dans le livre: "Play for Scala" mais j'obtiens une erreur de compilation sur la console de lecture:

C:\Play\exp\ch6_implicits>activator run

Application.scala est:

package controllers

import play.api._
import play.api.mvc._

// We extend the 'WithCart' trait, so we have an implicit conversion from RequestHeader to Cart
object Application extends Controller with WithCart {

  def index = Action { implicit request =>
    // The index template takes an implicit Cart, which is not available.
    // However, the WithCart trait has an implicit conversion from
    // RequestHeader to Cart, and we do have an implicit RequestHeader
    // here, because `request` is a Request, which extends RequestHeader.
    Ok(views.html.index())
  }

  def contact = Action { implicit request =>
    Ok(views.html.contact())
  }

}

Shop.scala est

package controllers

import play.api._
import play.api.mvc._
import models._

object Shop extends Controller with WithCart {

  def catalog() = Action { implicit request =>
    val products = ProductDAO.list
    Ok(views.html.products.catalog(products))
  }

}

Et le fichier routes est:

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

# Home page
GET     /               controllers.Application.index
GET     /catalog        controllers.Shop.catalog
GET     /contact        controllers.Application.contact

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

[ch6_implicits] $

Et la version Java est:

C:\Play\exp\ch6_implicits>Java -version
Java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

C:\Play\exp\ch6_implicits>javac -version
javac 1.8.0_45

Des idées, quel est le problème et comment résoudre ce problème?

Jusqu'à présent, d'autres exemples ont été compilés et fonctionnent sans erreur dans mon environnement.

Merci pour votre soutien!

Play 2.4, par défaut, génère un routeur à dépendance injectée, contrairement à ce qui était le cas auparavant, lorsqu'il utilisait un routeur statique. Vous avez deux options: supprimer la ligne routesGenerator de build.sbt afin que play génère un routeur statique, ou (mieux) crée vos classes de contrôleurs au lieu d'objets, et utilisez l'injection de dépendance.

supprimer routesGenerator: = InjectedRoutesGenerator du fichier build.sbt et tout fonctionnera

Changez votre objet en une classe comme celle-ci:

object Shop extends Controller with WithCart {
class Shop extends Controller with WithCart {

object Application extends Controller with WithCart {
class Application extends Controller with WithCart {
