title: How do I create dynamically named folders with Maven Archetype?
body: <p>I'm trying to build an archetype structure like this, a webapp with some custom folders for our web framework. Especially some dynamic folders which also will contain some files brought by the archetype.</p>
  
  <pre><code>└───src
      └───main
          └───webapp
              └───WEB-INF
                  ├───cfg
                  │   ├───log4j
                  │   └───resources
                  │       └───extensions
                  │           ├───${shortName}-business
                  │           └───${shortName}-layout
                  └───lib
  </code></pre>
  
  <p>I added a required property to my <code>archetype-metadata.xml</code> to have an short name for the project, which is used among other things for generating unique folders.</p>
  
  <pre><code>&lt;requiredProperties&gt;
    &lt;requiredProperty key="shortName" /&gt;
  &lt;/requiredProperties&gt;
  </code></pre>
  
  <p>The property <code>shortName</code> I use in a <code>fileSet</code>:</p>
  
  <pre><code>&lt;fileSet&gt;
    &lt;directory&gt;[..]/resources/extensions/${shortName}-business&lt;/directory&gt;
  &lt;/fileSet&gt;
  
  &lt;fileSet&gt;
    &lt;directory&gt;[..]/resources/extensions/${shortName}-layout&lt;/directory&gt;
  &lt;/fileSet&gt;
  </code></pre>
  
  <hr>
  
  <p>The command to generate the archetype:</p>
  
  <pre><code>mvn archetype:generate -B \
         -DgroupId=com.stackoverflow \
         -DartifactId=stackoverflow-question -DarchetypeGroupId=com.stackoverflow \
         -DarchetypeArtifactId=stackoverflow-archetype -DarchetypeVersion=1.0 \
         -DshortName=soq
  </code></pre>
  
  <p>I assume to get the following folder structure:</p>
  
  <pre><code>..\
     ├───soq-business
     └───soq-layout
  </code></pre>
  
  <p>But I get this name <code>${shortName}-business</code> as folder, without  it being replaced with the property.</p>
  
  <pre><code>..\
     ├───${shortName}-business
     └───${shortName}-layout
  </code></pre>
  
  <p>How can I achieve this? How can I place files below <code>soq-business</code> without knowing the folder name at this time?</p>
