nothing show now. is there anyway i can load it in terminal? that should work.
Make a folder on the desktop and name it minecraft put craftbukkit in there.
cd /home/{user}/Desktop/minecraft
java -Xmx1024M -Xms1024M -jar craftbukkit-0.0.1-SNAPSHOT.jar
Like I said you need java installed. I used to use Ubuntu now I just use centos to manage my servers so it's pretty hard to remember both so sorry if I got it wrong, I believe it is correct though.
Just remember to install java, I think sun java and java-jdk work. Search it in software package manager.
