接下来将尝试 update，看看这是否是一个损坏的更新。

1. Waiting for source changes... (press enter to interrupt)
update 之后错误似乎消失了。我现在还有其他编译错误，所以还不能 100% 确定一切都很好。
留下问题以防堆栈跟踪帮助其他人...
update 看来毕竟是这里的灵丹妙药。
仍然不确定为什么它会启动该过程...
我在配置多项目构建时遇到了同样的问题。
只需添加 "com.typesafe.play" %% "play-docs" % "2.4.x"
libraryDependencies 或使用 libraryDependencies ++= Seq(...) 而不是 libraryDependencies := Seq(...).
这发生在我工作中途关闭计算机后，我从 git 进行了清理，然后进化并再次运行
