gradle - 将属性添加到 JavaPlugin 的 SourceSets、Gradle

Question

我们正在尝试起草一个自定义 Gradle 插件来使用我们的建模语言 Umple 。我们希望使其尽可能“符合人体工程学”，并允许在“sourceSet”级别指定属性。

例如，

sourceSets {
  main { 
    umple {
      foo = 'bar'
    }
  }
}

umple { // defaults
  foo = 'baz'
}

我们尝试向源集添加扩展，并尝试按照 Scala 和 Antlr 插件的工作方式对方法进行建模。但是，我们无法弄清楚如何向 sourceSet 闭包应用程序添加额外的属性。如有任何帮助，我们将不胜感激。
