ANT: Start .bat file in new command prompt

Example:  On Build success, server should start by ANT itself.

<target name="build-commerce" depends="init, clean-all, build-all, build-ear">
  <exec executable="cmd" dir="C:/Users/<user>/Desktop/">
            <arg value="/c"/>
            <arg value="start"/>
            <arg value="Commerce.bat"/>
   </exec>
 </target>
