@Leo38638 You created a new instance of the main class, which you can't do. Use constructors instead.

 

Yep Solved my problem but commands not working :V
(Sry if this is noob, but Im noob on java):

CommanManager:

Code:

@Leo38638 It's always best to learn Java before doing anything with Bukkit. Bukkit is simply an implementation of Java, and you don't learn to walk before you learn to crawl. Addressing your problem with commands, is there another stack trace? If so please post it.

 

Yep:
