Add InstallerListener to IzPack installer project with Maven

Question

I have a working IzPack installer project set up with maven and added following to my install script install.xml to [installation][listeners]:

<listener classname="(company-name).listener.InstallerListener" stage="install"/>

Sadly, the line seems to be ignored and the debugger does not halt on set breakpoints in the InstallListener class. I have read the documentation for InstallListeners, but it is not useful as I have the build process integrated with maven; here are the relevant parts of the Project Object Model pom.xml:

<properties>
    <izpack-standalone.version>4.3.1</izpack-standalone.version>
</properties>

<dependencies>
    <!-- izpack -->
    <dependency>
        <groupId>org.codehaus.izpack</groupId>
        <artifactId>izpack-standalone-compiler</artifactId>
        <version>${izpack-standalone.version}</version>
        <optional>true</optional>
    </dependency>
</dependencies>

<plugins>    
    <!--  IzPack compiler  -->
    <plugin>
        <groupId>org.codehaus.izpack</groupId>
        <artifactId>izpack-maven-plugin</artifactId>
        <version>${org.codehaus.izpack.izpack-maven-plugin.version}</version>
        <dependencies>
            <dependency>
                <groupId>org.codehaus.izpack</groupId>
                <artifactId>izpack-standalone-compiler</artifactId>
                <version>${izpack-standalone.version}</version>
            </dependency>
        </dependencies>
        <configuration>
            <izpackBasedir>${staging.dir}</izpackBasedir>
            <customPanelDirectory>${staging.dir}</customPanelDirectory>
        </configuration>
        <executions>
            <execution>
                <id>standard-installer</id>
                <phase>package</phase>
                <goals>
                    <goal>izpack</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
</plugins>

What am I missing here?

Note: The compiled installer does contain the specified InstallerListener class file, so it is available at runtime.

Answer 1

You must place the jar file containing your panel classes into the {customPanelDirectory}/bin/panels folder where it will be picked up automatically by the izpack-maven-plugin.

In the case above this folder would resolve to {staging.dir}/bin/panels since you configured <customPanelDirectory>${staging.dir}</customPanelDirectory>.

Adding it to install.xml file will not work, since this would be resolved at install time, but not at installer build time.
