    I can read, thanks ;)

    Since the client administrator with little knowledge of Java is
    deploying this package, I am trying to make the installation steps as
    few/simple as possible, otherwise I have to spend time supporting the
    installation process, time and time again.

    Is there a reason why the <taskdef> does not work with a @classpathref
    in this case? @see http://ant.apache.org/manual/CoreTasks/taskdef.html

    Using this method of throwing all jars for all new tasks in the ANT
    environment seems quite intrusive and unnecessary. If I had to do this
    with each new taskdef for each script, the ANT lib directory would be
    crowded.

    This script defines <xep> and provides a valid classpath. My question
    is: why doesn't my script work with your ANT task when it has with
    others?

    Hello Kevin,

    Just add XEPTask.jar to the Ant CLASSPATH and the problem will gone.
    I mean CLASSPATH of the environment where Ant is being executed.
    By the way, in XEP Ant Task documentation it is stated as a first step
    of configuration. :-)
