title: Ant copy task ignoring files
body: <p>I have an Ant copy task (defined in a Maven script invoked by a Jenkins build) that appears to be correct but is not copying correctly.  The task is defined as</p>
  
  <pre><code>&lt;copy todir="./Virgo/config" overwrite="true" verbose="true"&gt;
      &lt;fileset dir="${config.folder}"&gt;
          &lt;include name="*.properties, *.xml" /&gt;
      &lt;/fileset&gt;
  &lt;/copy&gt;
  </code></pre>
  
  <p>When I run the task, I can see that the correct directory is specified, but the copy task doesn't select any files.  Both the source and destination directories exist, and I'm not getting any errors.  What I'm seeing is</p>
  
  <pre><code>14:52:40  [INFO] Executing tasks
  14:52:40  [DEBUG] getProperty(ns=null, name=ant.reuse.loader, user=false)
  14:52:40  [antlib:org.apache.tools.ant] Could not load definitions from resource org/apache/tools/ant/antlib.xml. It could not be found.

  14:52:40  [INFO] Executed tasks
  </code></pre>
  
  <p>I've tried adding files to the source directory, making the source files newer than the ones in the destination, even removing the files in the destination directory.  What bothers me is that it appears that the <code>fileset</code> isn't matching any files, even though the path is correct.  Has anyone ever seen this behavior before?</p>
