Any help would be nice, thank you

 

first line: package me.Rostik002;
Class name: FirstPlugin.java

 

What's in your plugin.yml?

 

Code:

name: FirstPlugin
main: me.bukkit.Rostik002.FirstPlugin
version: 1.0
commands:
   hello:
      description: Blank description.
      usage: /hello

 

@Rostik002 The problem is in your plugin.yml. Make sure you have correctly specified yor main class.

 

Thank you, turns out i had to use "me.Rostik002.FirstPlugin" and not "me.bukkit.Rostik002.FirstPlugin" in my plugin.yml

 

@Rostik002 Mark this thread as solved. And yes, You have to use your package at starting and at the end your main class name.
