Why re-invent? The standard Java mechanism is to provide the class path in the main jar's manifest. Existing Ant tasks will already handle that. Why is anything more than pointing to the main jar needed? The manifest in the main jar can be used to figure out what resources to bundle and the relative locations they need to be placed in. While raw .class files in folders could be referenced, it is highly unusual for an application to be distributed that way.
