How to create jar archive of projects sources with maven
===

I include the following snippet in a projects object model 

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-source-plugin</artifactId>
        <version>2.1.2</version>
      </plugin>

according to the <a href="http://maven.apache.org/plugins/maven-source-plugin/jar-mojo.html"> maven.apache.org</a> the plugin attaches the jar goal to the package phase.
However doing "mvn clean ; mvn package" does not generate a project-sources.jar in the target directory. Am i mistaking here? Or is maven?
