THE MANUAL BUILD TODO LIST Make a bin folder where you build ur files from eclipse or build script. Then turn output folder scrubbing off from eclipse. Next extract the whole bukkit into the bin folder. !! Then delete the com/google folder !! because otherways it will load those libs and FML wont work on old ones.

RUNNING IT java -classpath lib/*.jar;. -jar mcpc.jar nuff said that
