Take a look at the Ant Java Task. You should be able to create a target that looks like this:

<target name="mytarget" description="runs my class" >
  <java classname="test.Main">
    <classpath>
      <pathelement location="dist/test.jar"/>
    </classpath>
  </java>
</target>

Alternative, using Ant Exec Task:

<target name="mytarget" description="runs my class">
     <exec executable="java">
       <arg line="-classpath dist/test.jar test.Main"/>
     </exec>
</target>
