使用play framework v2.1.1，我们使用命令
play clean compile stage
生成可部署的工件。过去几个月它运作良好。我们没有改变任何东西，但现在当我再次尝试相同的命令时，它会抛出错误：

我再次设置播放，清理所有必需的目录但仍然没有成功。任何帮助将不胜感激。

我通过删除Java api文档的生成来解决此问题。这是我添加到build.sbt文件中的内容：
publishArtifact in (Compile, packageDoc) := false
publishArtifact in packageDoc := false
sources in (Compile,doc) := Seq.empty
