Problem with the Sheduler

Hey,
I've want to make a Sheduler in my Plugin as a Timer.
I put my Sheduler in an Seperated Class.

Everytime the Timer shut start it return's a Error Message.

Code:java

It says that 'Caused by: java.lang.IllegalArgumentException: Plugin cannot be null'.
But I think I declerated the Plugin.

At the Beginning of the Class with the Sheduler are this Code:

Code:java

    public static Main plugin;
 
    public Methodes(Main plugin) {
        Methodes.plugin = plugin;
    }

and in the Main class are:

Code:java

    public Main plugin;
 
    public void onEnable() {
 
//...
        plugin = this;
 
    }

I Don't want to put the Sheduler in the Main class so I need help...
If you need more Code say it, i will post it.

Instead of Methodes.plugin = plugin do this.plugin = plugin

 

Try:

Code:java

private Main plugin;
public Methodes(Main main){
  this.plugin = main;
 
}

 

Ohh...
Thaks guys...
The Plugin works fine now thx

I was so confused that I overreaded this.
