title: Error in mvn clean package -DskipTests
body: <p>I am new to maven. I am using following command to try building .ear for my project (which contains several other projects).</p>
  
  <pre><code>mvn clean package -DskipTests
  </code></pre>
  
  <p>Following is my error log:</p>
  
  <pre><code>[INFO] Scanning for projects...
  [ERROR] [ERROR] Some problems were encountered while processing the POMs:

  </code></pre>
  
  <p>And following is my entry of <code>com.mmm.ebus</code> in <code>pom.xml</code></p>
  
  <pre><code>&lt;parent&gt;
      &lt;groupId&gt;com.mmm.ebus&lt;/groupId&gt;

      &lt;version&gt;3.0.0.3&lt;/version&gt;
  &lt;/parent&gt;
  </code></pre>
  
  <p>Me and my colleague both have same code. It is running fine on her system but not on mine. What could have went wrong?
  I have already done <code>mvn clean</code>.</p>
  
  <p>Following is the trace of <code>mvn clean package -DskipTests -X</code></p>
