[William Mee <wm...@epo.org>]

I have seen this syntax used in many plugins, and I also do not get it to 
work. Seems like Jelly has a problem with the periods in the variable 
names? To test if the pom id is empty, for example, I have to do the 
following

      <!-- check that required information is there -->
      <j:set var="pomCurrentVersion" value="${pom.currentVersion}"/>
      <j:if test="${empty(pomCurrentVersion)}">
          <ant:fail>You must define currentVersion in your POM.</ant:fail>
      </j:if>

The test on pomp.currentVersion (${empty(pom.currentVersion)}) does not 
work.
