Using External Jar Files In Your Custom Ant Task Classpath.

It took me a while to figure out that I could specify several items in the classpath attribute of the taskdef tag in my build.xml file. Here is one example:

    <taskdef name="CreatePartition" 
        classname="org.wwre.ant.tasks.xis.CreatePartition" 
        classpath="build/classes;${xis.client.jar};${log4j.jar}"
    />
