title: what is for <excluded> tag in maven pom.xml file ?
body: <p>I know we use <code>&lt;exclusion&gt;</code> <code>&lt;excludes&gt;</code> <code>&lt;exclude&gt;</code>tags in maven pom.xml. I had to add a <code>jarmodule</code> to the maven pom file like below. </p>
  
  <pre><code>                    &lt;jarModule&gt;
                          &lt;groupId&gt;javax.transaction&lt;/groupId&gt;
                          &lt;artifactId&gt;jta&lt;/artifactId&gt;
                          &lt;excluded&gt;true&lt;/excluded&gt;
                      &lt;/jarModule&gt;
  </code></pre>
  
  <p>What is the <code>&lt;excluded&gt;</code> tag means there ? 
  This was added to the below plugin.</p>
  
  <pre><code> &lt;plugins&gt;
          &lt;plugin&gt;
              &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
              &lt;artifactId&gt;maven-ear-plugin&lt;/artifactId&gt;
              &lt;version&gt;2.5&lt;/version&gt;
               .........................
