Scala Play Framework 2.7.x编译时DI错误

从创建项目并获取编译错误

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

尝试播放2.6.23和2.7.2

从

MyApplication

中删除以下内容将使其正常工作：

override def applicationLifecycle: DefaultApplicationLifecycle

测试一下

git克隆https://github.com/playframework/play-socket.io.git

cd播放插座

从play socket.io/samples/scala/chat/app/modules/MyApplicationLoader.scala中删除覆盖

sbt“scalaChat/run”

从根项目目录

play socket/

击中

---

我得到了错误模块。MyApplicationLoader@6b1038e3]不是播放模块或GUI模块
