title: Plugin error: execution not covered by lifecycle configuration
body: <p>I am trying to use the maven-warpath-plugin <a href="http://static.appfuse.org/maven-warpath-plugin" rel="noreferrer">available here</a>. But I keep getting an error in my pom.xml file that says: </p>
  
  <blockquote>
    <p>Plugin execution not covered by lifecycle configuration: org.appfuse.plugins:maven-warpath-plugin:2.1.0:add-classes (execution: default, phase: generate-sources)</p>
  </blockquote>
  
  <p>How do I resolve this? Here is my pom.xml snippet for the plugin:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;plugin&gt;
      &lt;groupId&gt;org.appfuse.plugins&lt;/groupId&gt;
      &lt;artifactId&gt;maven-warpath-plugin&lt;/artifactId&gt;
      &lt;version&gt;2.1.0&lt;/version&gt;
      &lt;extensions&gt;true&lt;/extensions&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;goals&gt;
                  &lt;goal&gt;add-classes&lt;/goal&gt;
              &lt;/goals&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>Eclipse offers me a quickfox tip to "discover new m2e connectors" to resolve this error. I have installed most of the connectors available that seem to apply but the error is still there. Any ideas how I could make this work?</p>
