title: grails test-app -xml -coverage attempts to resolve XML URIs and times out
body: <p>I'm behind a proxy, and I need <code>grails test-app -xml -coverage</code> to NOT resolve whatever XML field it's trying to resolve and not connect to the internet.</p>
  
  <p>Any idea how to get this working? I need the proxy to <em>not</em> be set for the tests to work.</p>
