How to override jetty.xml with jetty.port

Question

I'm using maven-jetty-plugin and trying to override my jetty.xml setting with the -Djetty.port=8090 but it's not working. Only when I remove the connector part from the jetty.xml file I get the port to be 8090.

So:

 mvn jetty:run -Djetty.port=8090

With the connector starts in port 8080

Without the connector starts in port 8090

Problem is I need to configure acceptors, stats and other stuff. I tried removing only the port from the connector but it didn't work.

I'm using:

JAVA 1.7_05
MAVEN 3.0.4
Jetty 8.1.4
Linux Ubuntu 12.04 64bits

Here's my pom.xml plugin configuration:

<plugin>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>8.1.4.v20120524</version>
            <configuration>
                <stopKey>foo</stopKey>
                <stopPort>9990</stopPort>
                <jettyXml>src/main/webapp/WEB-INF/jetty.xml</jettyXml>
            </configuration>
            <executions>
                <execution>
                    <id>start-jetty</id>
                    <!-- <phase>pre-integration-test</phase> -->
                    <goals>
                        <goal>run</goal>
                    </goals>
                    <configuration>
                        <scanIntervalSeconds>0</scanIntervalSeconds>
                    </configuration>
                </execution>
                <execution>
                    <id>stop-jetty</id>
                    <!-- <phase>post-integration-test</phase> -->
                    <goals>
                        <goal>stop</goal>
                    </goals>
                </execution>
            </executions>
</plugin>

Jetty.xml connector conf:

<Call name="addConnector">
  <Arg>
      <New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <Set name="host"><Property name="jetty.host" /></Set>
        <Set name="port"><Property name="jetty.port" default="8080"/></Set>
        <Set name="maxIdleTime">300000</Set>
        <Set name="Acceptors">4</Set>
        <Set name="statsOn">false</Set>
        <Set name="confidentialPort">8443</Set>
    <Set name="lowResourcesConnections">20000</Set>
    <Set name="lowResourcesMaxIdleTime">5000</Set>
      </New>
  </Arg>
</Call>

Thanks in advance!

UPDATE 1: Also tried using SystemProperty instead of Property in the jetty.xml. Did not work

Answer 1

UPDATE 1: did work. Don't know why but I tried it with the host also as SystemProperty and it worked. Then I removed host and worked also.

So final fix working jetty.xml connector conf:

<Call name="addConnector">
  <Arg>
      <New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <Set name="host"><SystemProperty name="jetty.host" /></Set>
        <Set name="port"><SystemProperty name="jetty.port" default="8080"/></Set>
        <Set name="maxIdleTime">300000</Set>
        <Set name="Acceptors">4</Set>
        <Set name="statsOn">false</Set>
        <Set name="confidentialPort">8443</Set>
    <Set name="lowResourcesConnections">20000</Set>
    <Set name="lowResourcesMaxIdleTime">5000</Set>
      </New>
  </Arg>
</Call>
