This morning I tried changing the task to search for the Java source files, instead of the class files. It now appears to work perfectly fine from the command line, although I haven't verified any of the results yet. It's producing Java class files in my destination directory. I'm having trouble running the same task from Eclipse, but that appears to be some odd problem with the Ant classpath in Eclpse.
