In that case, is there an ant task that will enable me to explode the jar file and add the classes that way. I could simply explode the jars in my development hierarchy in Eclipse, but I would rather leave them untouched there and only explode them when I build the main jar file. I looked in the ant user's guide, and I couldn't find such a task, but is there a way to execute a short shell script from within the build.xml file?
