POAnt build failing with "UNEXPECTED TOP-LEVEL EXCEPTION (already added)"

Body
copied!<p>I've seen a lot of threads about this error, but none that cover my strange scenario. First the basics:</p> <p>I've got 6 projects, all of which are scaled down test projects that mimic my application's structure and which I'm using just to try to get the build working. Their dependencies are as follows:</p> <ul> <li><em>exampleLib</em> is a library that requires no other jars <ul> <li>contains Widget.java</li> </ul></li> <li><em>exampleLib2</em> is a library that requires no other jars <ul> <li>contains Widget2.java</li> </ul></li> <li><em>exampleLibNester</em> is a library that requires <em>exampleLib</em> and <em>exampleLib2</em> <ul> <li>contains WidgetPartDeux.java</li> </ul></li> <li><em>exampleLibNester2</em> is a library that requires <em>exampleLib</em>, <em>exampleLib2</em>, and <em>exampleLibNester</em> <ul> <li>contains WidgetPartDeux2.java</li> </ul></li> <li><em>exampleUser</em> is an application that requires <em>exampleLib</em>, <em>exampleLib2</em>, <em>exampleLibNester</em>, and <em>exampleLibNester2</em> <ul> <li>contains TheActivity.java</li> </ul></li> <li><em>exampleTest</em> is a test application that instruments <em>exampleUser</em> and requires <em>exampleLib</em>, <em>exampleLib2</em>, and <em>exampleLibNester</em> <ul> <li>contains WidgetTest.java</li> </ul></li> </ul> <p>When I build these applications using ant locally on windows they run fine and I can use <code>install test</code> to run the tests. When I try to build them on my CI server, which is running linux, I get the dreaded "already added" error message.</p> <pre><code>-dex: [dex] Converting compiled files and external libraries into /apps/pos360/jenkins/.hudson/jobs/James-Test/exampleLibUser/bin/classes.dex...
