title: Maven: Add older version of the same artifact as dependency
body: <p>Is it possible to add older version of the same artifact as dependency? 
  Here is an example: </p>
  
  <pre><code>&lt;groupId&gt;edu.illinois.cs.cogcomp&lt;/groupId&gt;
  &lt;artifactId&gt;illinois-pos&lt;/artifactId&gt;
  &lt;version&gt;2.0.3&lt;/version&gt;
  
  &lt;dependencies&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;edu.illinois.cs.cogcomp&lt;/groupId&gt;
          &lt;artifactId&gt;illinois-pos&lt;/artifactId&gt;
          &lt;version&gt;2.0.2&lt;/version&gt;
          &lt;classifier&gt;model&lt;/classifier&gt;
      &lt;/dependency&gt;
  &lt;/dependencies&gt;
  </code></pre>
  
  <p>If not, is there any way to make it work? </p>
