gradle - 如何在Gradle构建脚本中解析依赖项扩展

Question

我在maven-publish中使用了build.gradle插件。对于每个compile依赖项，group，name和version用于在生成的pom.xml文件中生成适当的标签-可以正常工作。

这是我有的示例依赖项:

dependencies {
  compile (
    [group: 'com.actionbarsherlock', name: 'actionbarsherlock', version: '4.4.0',  ext: 'aar'],
    [group: 'com.android.support',   name: 'support-v4',        version: '19.0.+']
  )}

这是我拥有的发布元素:

publishing {
  publications {
    // A publication named 'mavenAndroid'
    mavenPublishLibrary(MavenPublication) {
      // Artifact using the aar from the build output
      artifact "${project.projectDir}/build/outputs/aar/${project.name}-${project.version}.aar"

      // Generate dependencies manually for POM
      pom.withXml {
        def dependenciesNode = asNode().appendNode('dependencies')

        //Iterate over the compile dependencies, adding a <dependency> node for each
        configurations.compile.allDependencies.each {
          def dependencyNode = dependenciesNode.appendNode('dependency')
          dependencyNode.appendNode('groupId', it.group)
          dependencyNode.appendNode('artifactId', it.name)
          dependencyNode.appendNode('version', it.version)

          // This is what I'd want to do...
          if (it.ext != '') {
            dependencyNode.appendNode('type', it.ext)
          }
          // ...but this doesn't work!
        }
      }
    }
  }
}

我希望能够将 ext值(例如 aar)与 pom.xml， group和 name一起添加到 version中，就像上面片段中的内容一样。

当我奋斗了几个小时后，我会问这些问题，然后我似乎总是在问完之后很快就回答自己!

我使用以下代码获取依赖项扩展，替换了问题中的if():

it.getArtifacts().each {
  dependencyNode.appendNode('type', it.getExtension())
}
