How to start and stop Jetty from Ant

This example is a bit more complex than the one in this previous post How to start and stop Tomcat from Ant. Here, reuse of Ant code using “macrodef” is attempted. Also the start target is smart enough to stop the server if it is already running and the “sleep” is to give enough time for the server (2 seconds) to shutdown before restarting. I am using this approach successfully for Jetty 6.X

<macrodef name="jetty-start">
    <attribute name="arg1" default=""/>
    <attribute name="arg2" default=""/>
    <sequential>
        <antcall target="jetty-stop"/>
        <java jar="${jetty.home}/start.jar" fork="true" dir="${jetty.home}">
            <jvmarg value="-Dfile.encoding=UTF-8"/>
            <jvmarg value="-DSTOP.PORT=8079"/>
            <jvmarg value="-DSTOP.KEY=secret"/>
            <jvmarg value="@{arg1}"/>
            <jvmarg value="@{arg2}"/>
        </java>
    </sequential>
</macrodef>

<target name="jetty-check-status">
    <condition property="jetty.started">
        <socket server="localhost" port="8080"/>
    </condition>
</target>

<target name="jetty-start" depends="my-deploy-target">
    <jetty-start/>
</target>

<target name="jetty-start-debug" depends="my-deploy-target">
    <jetty-start
        arg1="-Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"
        arg2="-Xdebug"/>
</target> 

<target name="jetty-stop" depends="jetty-check-status" if="jetty.started">
    <java jar="${jetty.home}/start.jar" fork="true" dir="${jetty.home}">
        <jvmarg value="-DSTOP.PORT=8079"/>
        <jvmarg value="-DSTOP.KEY=secret"/>
        <arg value="--stop"/>
    </java>
    <sleep seconds="2"/>
</target>

Enforcing dependencies like performing an incremental compile & deploy before re-starting the server is IMHO much easier with Ant than using things like an IDE plugin, Cargo or Maven. Things like starting in debug mode are easy. Need to add a few more JVM parameters? No problem. Ant rulez :)
