I have been trying for the past...however long....to try and get CraftBukkit to compile/run. I've cloned the Git Repo, got Maven 3 running fine, and the build finishes successfully with no errors (I use mvn clean package). However, when I try to run the .jar file, I simply get this error: I've tried running it using both OpenJDK 6 and 7. Neither worked. What am I missing here? I can't find compiling docs anywhere!
