在Gradle中配置ScalaDoc任务以生成聚合文档

Question

我在Gradle中有一个多模块scala项目。除了ScalaDoc之外，一切都很好用。我想生成一个单独的'uber-scaladoc'与所有库交叉链接。我对groovy / gradle还很新，所以这可能是一个'我'的问题。任何获得此设置的帮助都将不胜感激。

build.gradle (in the root directory)

// ...

task doScaladoc(type: ScalaDoc) {

    subprojects.each { p ->

        // do something here?  include the project's src/main/scala/*?
        // it looks like I would want to call 'include' in here to include each project's
        // source directory, but I'm not familiar enough with the Project type to get at
        // that info.
        // 
        // http://www.gradle.org/docs/current/dsl/org.gradle.api.tasks.scala.ScalaDoc.html

    }
}

此处的目标是能够在命令行运行'gradle doScalaDoc'并显示聚合文档。

提前致谢。
