Bonjour, j'ai un petit problème ( gros en fait ) sur mon serveur avec essentials.
Je tiens à dire déjà que je suis sur MAC, je tiens à dire aussi que mon serveur est sous 1.11.2.
Bref dans mon dossier plugins :
- Essentials.jar
- EssentialsAntiBuild.jar
- EssentialsChat.jar
- EssentialsGroupManager.jar
- EssentialsProtect.jar
- EssentialsSpawn.jar
Ainsi que le dossier GroupManager, Essentials et PluginMetrics.
Sur le serveur quand j'execute la commande : /plugins
Tous sont en verts.
Quand je lances le serveur et que je vais dessus, un message blanc apparaît :
"Essentials failed to load, read the log file"
Et quand je fais une commande typique de Essentials, type : /ping ; /kits ; /kittycanon ;
Bref des commandes de Essentials, ça me dit en rouge :
"An internal error occurred while attempting to perform this command"
Bref voici le log du serveur quand je le lance (Attention aux yeux, c'est long ; je ne sais pas ce qui vous intéresse dans les logs donc je suis obligé de vous mettre tout) :

Salut à toi,

Pour GroupManager tu as :
Code:
[11:55:03 WARN]: [GroupManager] Plugin GroupManager vPre2.14.1.3 FINAL (Phoenix) generated an exception while executing task 2
java.lang.NoSuchMethodError: org.bukkit.Server.getOnlinePlayers()[Lorg/bukkit/entity/Player;

Le mot "NoSuchMethodError" Signifie en claire que la "méthode" est introuvable, en gros ta version de ton plugin est pas compatible avec celle de ton bukkit ou de spigot. Soit tu mets à jour ton plugin ou soit tu mets à jour ton bukkit ou spigot

Idem pour ton essentials :
Code:
[11:55:03 ERROR]: Error occurred while enabling Essentials v2.13.1 (Is it up to date?)
java.lang.NoSuchMethodError: org.bukkit.Server.getOnlinePlayers()[Lorg/bukkit/entity/Player;

Ps: Je te conseil fortement de passer sous Spigot si tu ne l'ai pas.

Cordialement,
Dredahox.

Ok Merci pour les conseils, juste 2-3 questions :

1). Quelle est la différence réelle entre Spigot et CraftBukkit ???
2). Les liens que vous m'avez envoyer c'est des plugins pour 1.11.2 ???

Merci Beacoup
 
Dernière édition:
1) Spigot est plus optimisé que bukkit
2) @belfedia as mis un lien qui affiche toutes les versions de essentials, a toi de choisir le bon (en l'occurance essentialsX pour minecraft 1.11.2)
 
Nan bah j'ai encore un problème, comme la 1.11.2 ça me saoulait trop xDDD
J'ai fait un serveur 1.8.8 Spigot : GroupManager marche mais toujours pas essentials
Avez vous des liens de essentials 1.8.8 ???
Cela vient peut-être de mon Java ???
PS : Je rappelle que je suis sur Mac
 
Ça veut dire quoi tout ce charabia ???
