A Better Maven POM for Wicket Archetypes

If you are new or just wants to try Apache Wicket there is a good Wicket Maven Archetype for that. You can find instruction for that at http://wicket.apache.org/start/quickstart.html.

But the generated pom.xml leafs room for improvement. A better pom would be

The differences I made are the following.

1. Downgrade the Jetty Maven Plugin to 7.5.0.v20110901

<jetty.version>7.5.0.v20110901</jetty.version>

The new jetty plugin are much slower than the old one and you want miss anything important.

2. Add Wicket Datetime Dependency

<dependency>
    <groupid>org.apache.wicket</groupId>
    <artifactid>wicket-datetime</artifactId>
    <version>${wicket.version}</version>
</dependency>

Wicket provides a good datetime picker and I recommend that you use this.

3. Configure Jetty Maven Plugin for Autodeploy

<scanintervalseconds>1</scanIntervalSeconds>

The jetty plugin can automatically be configure to pick up any changes made within Eclipse and automatically redeploy your application. This is a great way to develop and I recommend it.

<usetestclasspath>true</useTestClasspath>

You also might want to mock any possible server facade class, which is located in your test directory. To enable that add your web test classes to jetty classpath.
