Undeploy Extention(ext) plugin

For liferay We can undeploy using with ant.
We should add this script to built.xml

<property name="tomcat.home" value="${tomcat.name}"></property>
<echo>Application Name :"${app.name}"</echo>
<echo>Catalina Home :"${tomcat.home}\webapps\${app.name}-ext"</echo>

</target>
<target name="clean-ext">
<delete includeemptydirs="true">
<fileset dir="${tomcat.home}\webapps\${app.name}-ext" includes="**/*" />

</delete>
<echo>Deleting util-bridges.jar</echo>
<delete file="${tomcat.home}\webapps\ROOT\WEB-INF\lib\ext-${app.name}-ext-util-bridges.j

­ar"></delete>
