Overriding a plexus component declared in another plugin

Question

I'm currently writing a Maven plugin with automates releasing of modules by

• detecting if a module has changes which should be released
• releasing all modules using the maven-release-plugin
• adjusting dependencies in all affected projects

I'm trying to test it using the maven-invoker-plugin, which uses the following setup in the integration-test poms:

  <build>
    <plugins>
      <plugin>
        <groupId>@project.groupId@</groupId>
        <artifactId>@project.artifactId@</artifactId>
        <version>@project.version@</version>
        <executions>
          <execution>
            <id>my-id</id>
            <phase>generate-sources</phase>
            <goals>
              <goal>my-goal</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

The roadblock I'm hitting is that the maven-dependency-plugin forbids this release since I reference a SNAPSHOT plugin in my pom.xml ( the @project.version@ above ). Fair enough.

I discovered that this check is made in CheckDependencySnapshotsPhase , which is a plexus component:

@plexus.component role="org.apache.maven.shared.release.phase.ReleasePhase" role-hint="check-dependency-snapshots"

Can I somehow override this component and plug in my own? Alternatively, how can I run this integration test without being blocked by the 'no snapshot depenendencies' check?

Turns out the answer was right in front of me. Instead of configuring the plugin in the IT project pom.xml, just instruct the maven-invoker-plugin to execute it ( abridged ):

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-invoker-plugin</artifactId>
        <configuration>
          <goals>
            <goal>package</goal>
            <goal>${project.groupId}:${project.artifactId}:${project.version}:inspect-changes</goal>
          </goals>
        </configuration>
      </plugin>
