Answer 1

Using a plugin as a depency is wrong. If you like to execute a plugin you need to define that in an execution block

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>1.5.0</version>
        <executions>
          <execution>
            ...
            <goals>
              <goal>exec</goal>
            </goals>
          </execution>
        </executions>
        <configuration>
          <executable>maven</executable>
          <!-- optional -->
          <workingDirectory>/tmp</workingDirectory>
          <arguments>
            <argument>-X</argument>
            <argument>myproject:dist</argument>
            ...
          </arguments>
        </configuration>
      </plugin>
    </plugins>
  </build>
   ...
</project>
