-----------------------------------------------------

                 Key: MENFORCER-56
                 URL: http://jira.codehaus.org/browse/MENFORCER-56
             Project: Maven 2.x Enforcer Plugin
          Issue Type: Bug
            Reporter: Craig Russell
            Assignee: Brian Fox


With this snippet of metadata:
                <requireProperty>
                  <property>ndbj.jnilib2</property>
                  <message>"You must have a ndbj.jnilib2!"</message>
                </requireProperty>
                <requireFilesExist>
                  <files>
                   <file>${ndbj.jnilib2}</file>
                  </files>
                </requireFilesExist>

the variable ndbj.jnilib2  doesn't exist and results in:
