Maven plugin executing another plugin

maven-2plugins

I'm trying to create a new plugin to package my latest project. I'm trying to have this plugin depend on the maven-dependency-plugin to copy all my projects dependencies.

I've added this dependency to my plugin's pom, but I can't get it to execute.

I have this annotation in my plugins main Mojo:

@execute goal="org.apache.maven.plugins:maven-dependency-plugin:copy"

I've tried a few other names for the goal, like dependency:copy and just copy but they all end with a message saying that the required goal was not found in my plugin. What am I doing wrong?

Secondary to this is where to I provide configuration info for the dependency plugin?

Use the Maven Mojo executor by Don Brown of Atlassian fame to run any other arbitrary plugin.

The Mojo Executor provides a way to to execute other Mojos (plugins) within a Maven 2 plugin, allowing you to easily create Maven 2 plugins that are composed of other plugins.

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

and you run it with

mvn clean compile assembly:single

Compile goal should be added before assembly:single or otherwise the code on your own project is not included.

See more details in comments.

Commonly this goal is tied to a build phase to execute automatically. This ensures the JAR is built when executing mvn install or performing a deployment/release.

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>fully.qualified.MainClass</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
  <executions>
    <execution>
      <id>make-assembly</id> <!-- this is used for inheritance merges -->
      <phase>package</phase> <!-- bind to the packaging phase -->
      <goals>
        <goal>single</goal>
      </goals>
    </execution>
  </executions>
