<h2><a name="ant">Ant</a></h2>
<h3>Description</h3>
<p>Runs Ant on a supplied buildfile. This can be used to build subprojects.</p>
<p>When the <i>antfile</i> attribute is omitted, the file &quot;build.xml&quot;
in the supplied directory (<i>dir</i> attribute) is used.</p>
<p>If no target attribute is supplied, the default target of the new project is
used.</p>
<p>The properties of the current project will be available in the new project.
These properties will override the properties that are set in the new project.
(See also the <a href="property.html">property task</a>). You can set properties
in the new project from the old project by using nested property tags. This
allows you to parameterize your subprojects.</p>
