jetty-maven-plugin multiple wars separate ports

Question

I use the jetty-maven-plugin for local development testing. What I want is from a single jetty:run command, start a bunch of jetty containers on separate ports as specified in the pom.xml -- I don't want to specify it within the war. My current plugin configuration block looks like ::

<configuration>
   <scanIntervalSeconds>0</scanIntervalSeconds>
   <contextHandlers>
      <contextHandler implementation="org.eclipse.jetty.webapp.WebAppContext">
         <war>${basedir}/service-a/target/a.war</war>
         <contextPath>/a</contextPath>
         <allowNullPathInfo>true</allowNullPathInfo>
      </contextHandler>
      <contextHandler implementation="org.eclipse.jetty.webapp.WebAppContext">
         <war>${basedir}/service-b/target/b.war</war>
         <contextPath>/b</contextPath>
         <allowNullPathInfo>true</allowNullPathInfo>
      </contextHandler>
   </contextHandlers>
</configuration>

I know I can specify a -Djetty.port but that globally sets the port. The above example starts both wars in the same jetty container instance running on port 8080. Does anyone know a switch within contextHandler to set the port or how to do it if I have multiple instances of the entire plugin block? Every example I've searched for only has the option to set it in the jetty.xml file within the war which I don't want to do.

What would happen if you created multiple mvn modules under the main one that both received a jetty:run but with different configurations? (although that usually holds the console doesn't it) — DrLivingston

It's possible if you name the connectors and context handlers

<configuration>
    <connectors>
        <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
            <port>8080</port>
            <name>instance_8080</name>
        </connector>
        <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
            <port>8081</port>
            <name>instance_8081</name>
        </connector>
    </connectors>
    <contextHandlers>           
        <contextHandler implementation="org.eclipse.jetty.webapp.WebAppContext">
            <war>${basedir}/service-a/target/a.war</war>
            <contextPath>/a</contextPath>
            <connectorNames>
                <item>instance_8080</item>
            </connectorNames>
        </contextHandler>
        <contextHandler implementation="org.eclipse.jetty.webapp.WebAppContext">
            <war>${basedir}/service-b/target/b.war</war>
            <contextPath>/b</contextPath>
            <connectorNames>
                <item>instance_8081</item>
            </connectorNames>
        </contextHandler>
    </contextHandlers> 
</configuration>

Note, this configuration is for org.mortbay.jetty:jetty-maven-plugin.
