Play Framework 2.7.x Compile Time DI Error

Question

Create project from https://github.com/playframework/play-socket.io/tree/master/samples/scala/chat and get compilation error

overriding method applicationLifecycle in trait MyApplication of type => play.api.inject.DefaultApplicationLifecycle;
 lazy value applicationLifecycle in class BuiltInComponentsFromContext of type play.api.inject.ApplicationLifecycle has incompatible type

Try with Play 2.6.23 and 2.7.2

Answer 1

Removing the following line from MyApplication should make it work:

override def applicationLifecycle: DefaultApplicationLifecycle

Test it with

1. git clone https://github.com/playframework/play-socket.io.git
2. cd play-socket
3. Remove the override from play-socket.io/samples/scala/chat/app/modules/MyApplicationLoader.scala
4. sbt "scalaChat/run" from the root project dir play-socket/
5. Hit http://localhost:9000/
