Schedulers in a custom method give an error "this.(..)"

I'm making my custom method that has a bunch of consecutive schedulers that run a delayed task each. The problem is I'm using the "this" at the begging of each scheduler, and so, the method is showing red lines under "this" for some reason. Why and how can i solve this?

Code:java

    public static void muffin(Player player) {
        player.getInventory().clear();
        player.teleport(
                new Location(Bukkit.getWorld("diverge"), 0, 72, 0));
 
        player.getInventory().setHeldItemSlot(4);
 
        this.getServer().getScheduler()
                .scheduleSyncDelayedTask(this, new Runnable() {
                    @Override
                    public void run() {
 
                   -massive snip-
 
                    }
                }, 20L);
        this.getServer().getScheduler()
                .scheduleSyncDelayedTask(this, new Runnable() {
                    @Override
                    public void run() {
 
                   -snip-
 
                    }
                }, 25L);
        this.getServer().getScheduler()
                .scheduleSyncDelayedTask(this, new Runnable() {
                    @Override
                    public void run() {
 
                   -snip-
 
                    }
                }, 30L);
 
    }

 

You're referring to the instance of an object from within a static method. You should consider whether the method really needs to be static (probably not), if it does, you should use Bukkit.getServer(), if it doesn't remove the static keyword from the function declaration.
