title: Error when building with Android Annotations
body: <p>I'm using the guide <a href="https://github.com/excilys/androidannotations/wiki/Eclipse-Project-Configuration" rel="nofollow">here</a> to integrate Android Annotations in my Eclipse project (no Maven). I've got the latest ADT running, and tried cleaning my project, double checking build paths and order/export, and turning annotations on and off, but whenever I add the Android Annotations jar to the entries under <code>Java Compiler &gt; Annotation Processing &gt; Factory Path</code> in Eclipse, I get this error:</p>
