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>
