title: Apache Commons IO not getting added to jar
body: <p>I've recently added Apache Commons IO to a small project of mine so that I can tail a log file.  Everything works great in my IDE (IntelliJ), but when I create the executable jar, Commons IO isn't in there, so I get : </p>
  
  <blockquote>
    <p>Exception in thread "main" java.lang.NoClassDefFoundError:
    org/apache/commons/io/input/TailerListener.</p>
  </blockquote>
  
  <p>Commons IO has been added to my POM:</p>
  
  <blockquote>
  <pre><code>&lt;dependency&gt;
       &lt;groupId&gt;commons-io&lt;/groupId&gt;
       &lt;artifactId&gt;commons-io&lt;/artifactId&gt;
       &lt;version&gt;2.1&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>

  <p>I've never had issues with added dependencies like this before.  What am I missing?</p>
