Maven - POM: How to make the jetty port changeable so that it can be retrieved later? - maven-2

Question

I'm working on an integration test suite and I've got a question for you.
My parent pom defines the use of the jetty plugin with the goal: run-war. I need to make the port that jetty listens on changeable via the command-line. This can be achieved by passing -Djetty.port=8099 for example.
In the child project, I need to use this port number to configure the endpoint for some SOAP tests that I'll need to run on the service hosted by jetty.
If I use ${jetty.port} in my child pom in the end-point configuration this works fine IF and only IF I explicitly pass -Djetty.port when invoking maven.
In my child pom:
<endpoint>http://127.0.0.1:${jetty.port}/{artifactId}<endpoint>
I need jetty.port to be filled in with 8080 which is what jetty defaults to if -Djetty.port is not explicitly passed, and still catch any other port values if the command line argument is specified.

Answer 1

Use the properties section, and add a jetty.port property with a default value:
<properties>
<jetty.port>8080</jetty.port>
</properties>

Answer 2

config maven jetty plugin:
<plugins>
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<version>6.1H.14.1</version>
<configuration>
<connectors>
<connector implementation="org.mortbay.jetty.nio.SelectChannelConnector">
<port>8085</port>
<maxIdleTime>60000</maxIdleTime>
</connector>
</connectors>
</configuration>
</plugin>
</plugins>
If you want to use a newer version of jetty plugin, use the following configuration:
From http://www.eclipse.org/jetty/documentation/current/jetty-maven-plugin.html:
You could instead configure the connectors in a standard jetty xml config file and put its location into the jettyXml parameter. Note that since jetty-9.0 it is no longer possible to configure a https connector directly in the pom.xml: you need to use jetty xml config files to do it.
Something like:
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.0.5.v20130815</version>
<configuration>
<jettyXml>src/main/resources/jetty.xml</jettyXml>
<webApp>
<contextPath>/yourCtxPath</contextPath>
</webApp>
</configuration>
</plugin>
would do the trick, with
jetty.xml file content:
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure id="Server" class="org.eclipse.jetty.server.Server">
<Call id="httpsConnector" name="addConnector">
<Arg>
<New class="org.eclipse.jetty.server.ServerConnector">
<Arg name="server"><Ref refid="Server" /></Arg>
<Set name="host"><Property name="jetty.host" /></Set>
<Set name="port"><Property name="jetty.port" default="8085" /></Set>
<Set name="idleTimeout">30000</Set>
</New>
</Arg>
</Call>
</Configure>
See the log after 'mvn jetty:run', at the end should show something like:
2013-09-05 09:49:05.047:INFO:oejs.ServerConnector:main: Started ServerConnector#a6e9cb4{HTTP/1.1}{0.0.0.0:8085}
You will need to use maven 3 and java 7 for this version of plugin.
