title: Legacy IzPack in ant issue
body: <p>I have an old ant script I am trying to run to create an installer for some legacy software.  </p>
  
  <p>The check for whether IzPack is installed is failing, even though I have installed IzPack 5.0</p>
  
  <p>Here is the ant file segment for that check:</p>
  
  <pre><code>  &lt;target name="check-izpack" depends="init-build"&gt;
      &lt;available property="izpack.present"
                 classname="com.izforge.izpack.ant.IzPackTask"
                 classpathref="installer.cp" /&gt;
      &lt;fail unless="izpack.present"&gt;.
  
         The IzPack program is not available.  Download it from
         http://www.izforge.com/izpack/.  Install it, and set the
         'izpack.home' property in your local build.properties.
      &lt;/fail&gt;
      &lt;taskdef name="izpack" classname="com.izforge.izpack.ant.IzPackTask"
               classpathref="installer.cp"/&gt;
    &lt;/target&gt;
  </code></pre>
  
  <p>And further down:</p>
  
  <pre><code>  &lt;path id="installer.cp"&gt;
      &lt;path refid="classpath" /&gt;
      &lt;pathelement location="${izpack.home}/lib/standalone-compiler.jar"/&gt;
    &lt;/path&gt;
  </code></pre>
  
  <p><code>izpack.home</code> is set to the appropriate location in my build.properties file.  But I notice that in the <code>/lib</code> directory, there is no jarfile named <code>standalone-compiler.jar</code> which I understand was something from older versions of IzPack.  </p>
  
  <p>Is there a way I can make this work?  (Preferably without me needing to learn all about IzPack and ant.) If I can get my hands on an appropriate legacy version of IzPack would that be the easiest way to go?  Or is there an easy conversion for the new IzPack that might work for me?</p>
