Solved BukkitRunnable won't cancel

Hi,
I am kind of new to plugins development and I created a BukkitRunnable wich inside of it I wrote "this.cancel()" at the end. The fact is when I want to start the same thread again, this error message show up in the console :

"java.lang.IllegalStateException: Already scheduled as 9895"

So, I don't know if I did something wrong or not

Thanks in advance

 

Ok so, there is my code, i also tried to use a command to cancel the task with the task id that show up in the server console

My Main class :

Code:

                start.runTaskAsynchronously(this);
            }

        }

    }

}

My Start class :

Code:

package io.github.Natank25.HideAndSeek;

import org.bukkit.Bukkit;
import org.bukkit.scheduler.BukkitRunnable;

public class Start extends BukkitRunnable {

    //private Main main;

    public Start(Main mainCMD) {
        //this.main = mainCMD;
    }

    public void run() {
            Bukkit.broadcastMessage("MAN, I CAN'T believe IT'S WORKING");

      
        this.cancel();
    }

}

and finally my cancelTaskExecutor class :

Code:

package io.github.Natank25.HideAndSeek;

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class cancelTaskExecutor implements CommandExecutor {
    private final Main plugin;

    public cancelTaskExecutor(Main plugin) {
        this.plugin = plugin;
    }
  
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (sender instanceof Player) {
            sender.sendMessage(args);
            Bukkit.getScheduler().cancelTask(Integer.parseInt(args[0]));
            return true;
        }
        return false;
    }

}

Thank for your help

Nevermind, i got it working

I just replaced

Code:

 if (hiderReady && hunterReady) {
     start.runTaskAsynchronously(this);
}

by

Code:

 if (hiderReady && hunterReady) {
    new Start(this).runTaskAsynchronously(this);
}
