Using a Custom Announcement Template

The announcement goal uses a Velocity template to create an announcement. If you want to, you can create your own custom template.

Configuring the Plugin

First you must configure the plugin and tell it where your template is. In this example we want to use the template ${basedir}/src/main/resources/our-announcements/my-announcement.vm.

Note: The <templateDirectory> must be a subdirectory of ${basedir}/src/main/resources/.

<project>
  ...
  <reporting>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-changes-plugin</artifactId>
        <version>2.4</version>
        <configuration>
          <template>my-announcement.vm</template>
          <templateDirectory>our-announcements</templateDirectory>
        </configuration>
      </plugin>
    </plugins>
  </reporting>
  ...
</project>

Creating Your Template

Next you want to create your own template. A wise thing is to start with the default one that is included in the plugin. You can download it from Subversion here. It will provide you with examples on how to iterate over the actions of a release among other things.

Available Variables

Here's a list of the variables that you have at your disposal, when creating your own template:

Variable Type Since Description
