Solved InvalidPluginException

I've tried looking everywhere and found no solution, I don't know what's causing this error
The error says Line 11 which is the start of my onEnable method.

Error:

onEnable:

Code:

public void onEnable()
   {
        if(!getDataFolder().exists())
            getDataFolder().mkdir();

        if(getConfig() == null)
        {
            getConfig().addDefault("Swords", 0);
            getConfig().addDefault("Axes", 0);
            getConfig().addDefault("Bow", 0);
            saveDefaultConfig();
            getConfig().options().copyDefaults();
        }
       
        registerEvents();
    }

 

@Blackwing_Forged
Can you post the full class? The error message states that you are trying to get an object from a static initialize, which is not something the code posted is doing.

 

@Zombie_Striker
would it be this:
static Plugin pl = DamageMain.getPlugin(DamageMain.class);

EDIT: I got it, i looked up better ways to get the plugin instance and that worked, thanks anyway
