Play Framework For Scala: Kompilierungsfehler [Typ Anwendung ist kein Mitglied von Paketcontrollern]

Ich versuche, ein Scala-Beispiel in dem Buch zu kompilieren: "Play for Scala", bekomme jedoch einen folgenden Kompilierungsfehler auf der Play-Konsole:

Application.scala ist:

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 ist

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))
  }

}

Und routen datei ist:

# 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)

Play Framework ist 2.4.0 und sagt ungefähr:

Und Java-Version ist:

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

Irgendwelche Ideen, was ist das Problem und wie kann ich das beheben?

Bisher wurden andere Beispiele kompiliert und laufen ohne Fehler in meiner Umgebung.

Danke für Ihre Unterstützung!

Bei Wiedergabe 2.4 wird standardmäßig ein abhängiger injizierter Router erzeugt, anders als zuvor, wenn ein statischer Router verwendet wurde. Sie haben zwei Optionen: Entfernen Sie die linesGenerator-Zeile aus build.sbt, sodass play einen statischen Router generiert, oder (besser) machen Sie Ihre Controller-Klassen anstelle von Objekten und verwenden Sie die Abhängigkeitseingabe.

James Roper

entfernen Sie routesGenerator: = InjectedRoutesGenerator aus Ihrer Build-Datei

Ändern Sie Ihr Objekt in eine Klasse wie folgt:

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

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