Problem with onCommand and CommandExecutor...

Hi, I've been having trouble with using onCommand and CommandExecutor as I haven't used commands in any Bukkit Plugin before and I'm working on my first one which is UnlimitedHealth. When I try to run my plugin on my bukkit server, it gives me this error:

If any of you can find the error and let me know how to fix it, it will be greatly appreciated.

the error:

Code:

PLEASE HELP!!!!

 

Remove the package line from the yaml, and ensure that your commands are indented properly (with spaces)

 

same problem

here's what my plugin.yml looks like now(used spaces)

Code:

name: UnlimitedHealth
main: me.lionking23.UnlimitedHealth.UnlimitedHealth
version: 1.2
commands:
    god:
        description: Unlimited health! WOOT!
        usage: /god
    ungod:
        description: No unlimited health... :(
        usage: /ungod

 

That's odd. Try renaming your core plugin class to UnlimitedHealthPlugin (you'll also need to rename the file and adjust your main entry in the plugin.yml.) I'm thinking that there might be an issue arising from multiple appearances of the string "UnlimitedHealth."

Also, verify that there are no compilation errors when compiling the jar. I know for a fact that eclipse will allow you to build a jar even if there are errors in the code that prevent the class files from being compiled.

Side-Note: you posted in the wrong forum. Post in the general Plugin Development forum next time for any issues or need of assistance.

 

Okay, thanks.
