title: ant delete task with wildcard not working
body: <p>I would like to set up an ant task to delete all .class and .jar
      files from the same directory the build.xml file is, including
      nonsense.class which is in the same directory as the build.xml
      file. So I've set up the following build.xml file for ant 1.9.0
      as follows:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;project name="HelloWorld" default="deploy"&gt;
    &lt;!-- ... --&gt;
    &lt;target name="clean"&gt;
      &lt;delete file="nonsense.class" /&gt;
      &lt;delete file="*.class" /&gt;
      &lt;delete file="*.jar" /&gt;
    &lt;/target&gt;
  &lt;/project&gt;
  </code></pre>
  
  <p>When I execute it nonsense.class is removed but none of
  the other .class or .jar files. What am I doing wrong?</p>
