title: Maven Shade Plugin not attaching shaded artifact
body: <p>I'm trying to use the maven-shade-plugin to distinguish between Java 6 and Java 7 artifacts.  My understanding from <a href="http://maven.apache.org/plugins/maven-shade-plugin/examples/attached-artifact.html" rel="nofollow">this link</a> is that the original artifact will be replaced by the shaded one    </p>

  <p>However, it is installing without the SHADED classifier.  Here is my shade plugin configuration:</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
      &lt;artifactId&gt;maven-shade-plugin&lt;/artifactId&gt;
      &lt;version&gt;2.3&lt;/version&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;phase&gt;package&lt;/phase&gt;
              &lt;goals&gt;
                  &lt;goal&gt;shade&lt;/goal&gt;
              &lt;/goals&gt;
              &lt;configuration&gt;
                  &lt;shadeTestJar&gt;true&lt;/shadeTestJar&gt;
                  &lt;shadedClassifierName&gt;SHADED&lt;/shadedClassifierName&gt;
              &lt;/configuration&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>Can anyone tell me how to get it to install with the proper classifier?  Also, I'm using this instead of the maven-jar-plugin because I need to be able to classify test jars as well.</p>
