描述并行执行的常春藤依赖项

Question

我有一个基于常春藤的构建，我的顶级构建脚本（简单就好）就像：

<target name="buildlist">
  <ivy:buildlist reference="build-path">
    <fileset dir="." includes="*/**/build.xml"/>
  </ivy:buildlist>
</target>


<target name="all" depends="buildlist" description="build, publish and report for all projects">
  <echo message="Calling 'all' on ${toString:build-path}."/>
  <subant target="all" buildpathref="build-path"/>
</target>

真正酷的是能够并行化构建。例如，ivy知道依赖关系并且可以指示哪些子调用可以并行运行。有人做过这样的事吗？
