Bonsoir, j'essai d'installer forge 1.8 mais j'ai un soucis en voulant lancer le jeu.
Sans le mod, le jeu marche mais avec, j'ai ce message que je ne comprend pas
"Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/Level

Quelqu'un pourrais me dire ce qui ne va pas??
