如何将wro4j与Closure库和编译器一起使用？

Question

I followed the instructions at here , though I substituted 1.3.8 for the version, and I'm able to compile my JS in a wildcard folder as I wanted, however, I'm not quite sure where to place the closure library files so the compiler will pick them up. Where is this configured?

Add the js assets required by google closure (the ones containing "goog.dom" object) to the wro.xml model. Example:

    <groups>
      <group name="closure">
        <js>/path/to/goog-dom.js</js>
        <js>/files/*.js</js>
      </group>
    </groups>

If this doesn't help, post the same question on google closure & wro4j mailing list (to target the right audience). You could also provide a more detailed example with a quickstart project which would help to reproduce the problem.
