Answer 1

Play 2.4, by default, generates a dependency injected router, unlike previously, when it used a static router. You have two options, remove the routesGenerator line from build.sbt so play will generate a static router, or (better) make your controllers classes instead of objects, and use dependency injection.

Answer 2

Include below code into into your conf/application.conf file:

play.allowGlobalApplication = true

Answer 3

remove routesGenerator := InjectedRoutesGenerator from yout file build.sbt and all will work

Answer 4

Change your object to a class like this:

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

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