Change default mojo configuration in lifecycle mapping

问题

I'm writing a Maven 3 plugin which builds plugins for another application. A plugin is basically a JAR file with some fancy manifests. The compiled classes need to be post-processed for the plugin to work with the production build of the host application. Unfortunately, the processed version of the plugin won't work with the debug build of the host. I therefore need to produce two artifacts: the raw classes with the classifier debug and the post-processed version as the main artifact.

I've got a working Maven plugin which defines a new packaging type with its own lifecycle mappings. In order to create the debug artifact, though, I need to call jar:jar with the classifier property set. I haven't been able to find a way to change the configuration for a Mojo execution from a lifecycle mapping. Is that even possible? Will I have to make everyone use a super POM provided with my plugin?

For reference, here's the relevant part of my components.xml:

<?xml version="1.0" encoding="utf-8" ?>
<component-set>
  <components>
    <!-- snip other components, including ArtifactHandler -->
    <component>
      <role>org.apache.maven.lifecycle.mapping.LifecycleMapping</role>
      <role-hint>my-packaging</role-hint>
      <implementation>org.apache.maven.lifecycle.mapping.DefaultLifecycleMapping</implementation>
      <configuration>
        <lifecycles>
          <lifecycle>
            <id>default</id>
            <phases>
              <!-- snip other phases -->
              <package>
                org.apache.maven.plugins:maven-jar-plugin:jar
              </package>
            </phases>
          </lifecycle>
        </lifecycles>
      </configuration>
    </component>
  </components>
</component-set>

I need the execution to be equivalent to this POM fragment:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <executions>
    <execution>
      <id>debug-jar</id>
      <phase>package</phase>
      <goal>jar</goal>
      <configuration>
        <classifier>debug</classifier>
      </configuration>
    </execution>
  </executions>
</plugin>

I found one SO question that seems to be the same thing I'm looking for but it doesn't have any answers. This is the documentation that I used to create the lifecycle mapping in the first place. Heavy Googling hasn't turned up anything that seems related, but I'm having trouble coming up with sufficiently specific search terms.
