My plugins.yml :

Code:

main: net.exs.FightCube.FightCubeMain
nom: FightCube
version: 1.0
auteur: Exs
description: Un exemple de plugin
commandes:
    start:
    description: un exemple de commande
    utilisation: /start

Some one can found what is wrong ?
thanks.

 

oki thank i don't notice that !

 

Also your spacing is wrong in the commands. That plugin.yml will have commands start, description and utilisation the way you have it setup. Sub items need to be indented beneath the parent level.
