记录以防其他人遇到此事。
截至今天没有谷歌针对具体问题的结果。

到目前为止clean尚未解决此问题。
将退出并重试尽可能多的事情，但这个错误只是出现在没有的地方 - 我在另一个窗口运行规范测试并且它触发了更新（为什么？），这就是问题时（ s）开始了。
接下来会尝试update，看看这是不是更新了。
这是发生错误的堆栈跟踪。

1. Waiting for source changes... (press enter to interrupt)
update错误后似乎消失了。我现在有其他的编译错误，所以不是100％肯定一切都很好。
如果堆栈跟踪有助于其他人......
答案 0 :(得分：1)
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"
到libraryDependencies或使用libraryDependencies ++= Seq(...)代替libraryDependencies := Seq(...)。

update似乎是神奇的药丸。
仍然不确定为什么它开始这个过程......
