Solved Stop and restart a BukkitRunnable task

Part of my plugin involves an item generator that can be upgraded. When the an instance of the Generator class (which extends BukkitRunnable) is created, a task is scheduled and run. This is my current code for the upgrade process:

Code:

public void levelUp()
    {
        level++;
        if(level == 0)
            level++;
  
        turnOff();
        calcTime();
        calcUpgradeCost();
        turnOn();
  
        Sign sign = (Sign)loc.getBlock().getState();
        sign.setLine(2, ChatColor.DARK_RED + "Level " + level + " (" + getTimeInSeconds() + "s)");
        sign.update();
    }

Relevant Methods:

• turnOff - runs this.cancel()
• turnOn - runs this.runTaskTimer(main, 0, time)

When this method is run, it throws an error into the console stating that the task is already scheduled, giving the task ID.

I was under the impression that when a task is canceled, the scheduler forgets about it. Apparently, that is not the case. As such, what should I do instead to restart the task with the recalculated time (result of running calcTime())?

Thanks in advance for the help!

Solved. I changed it from BukkitRunnable to Runnable and made adjustments.
