No Stack Information - V(Unknown Source)
<p>I am having a problem with my app, and wondering why I am not getting any stack information just;</p>

<pre>
    java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
            at com.x.y.z.()V(Unknown Source)
</pre>

<p>I am building using an Ant script - do I need to fiddle with some sort of compilation verbosity setting?</p>

<p>P.S. I am not interested in the NoClassDefFoundError, just the lack of stack trace.</p>
