Magic - included resources for custom Ant task (magic plugin?)

Without understanding how to build a magic plugin, I went forward with 
creating ant tasks for my project, xsd2jibx, with standard ant includes.
http://cvs.sourceforge.net/viewcvs.py/jibx/xsd2jibx/ant-xsd2jibx-task.xml?rev=1.2&view=markup

<?xml version="1.0" encoding="UTF-8" ?>
<project xmlns:x="antlib:org.apache.avalon.tools">
  
  <x:property name="xsd2jibx.path" key="xsd2jibx" feature="path"/>
  <x:property name="xpp3.path" key="xpp3" feature="path"/>
  <x:property name="jibx-run.path" key="jibx-run" feature="path"/>
  <x:property name="commons-logging.path" key="commons-logging" feature="path"/>
  <x:property name="jaxmejs.path" key="jaxmejs" feature="path"/>
  <x:property name="log4j.path" key="log4j" feature="path"/>
  
  <path id="xsd2jibx.classpath">
    <fileset dir="${magic.cache}" includes="
       ${log4j.path},
       ${xsd2jibx.path},
       ${jibx-run.path},
       ${xpp3.path},
       ${commons-logging.path},
       ${jaxmejs.path}"/>
  </path>
  
  <taskdef name="xsd2jibx" classname="org.jibx.xsd2jibx.GeneratorAntTask">
    <classpath>
      <path refid="xsd2jibx.classpath"/>
    </classpath>
  </taskdef>
  
</project>


The issue that I run into is that other projects that wish to use 
xsd2jibx must reference all those resources.
http://cvs.sourceforge.net/viewcvs.py/jibx/xsd2jibx/resources-common.xml?rev=1.3&view=markup

I was hoping that I could have some ant variables to work with in 
index.xml, but no such luck.
  <import index="../xsd2jibx/magic/resources-common.xml"/>
  <!--<import index="${xsd2jibx_home}/magic/resources-common.xml"/>-->

Is the magic plugin mechanism a better approach?  If yes, how can I use 
it in this situation.

Thanks,
Cameron
