Reset the repeating task

How do I reset the repeating task without having to reload the server?

Code:

@SuppressWarnings("deprecation")
    @EventHandler
    void onHitWW(EntityDamageByEntityEvent e) {
        final Player p = (Player) e.getDamager();
        if (p.getItemInHand().hasItemMeta()) {
            if (p.getItemInHand().getItemMeta().hasDisplayName()) {
                if (p.getItemInHand().getItemMeta().getDisplayName()
                        .equals("Werewolf Sword")) {
                    if (p.hasPotionEffect(PotionEffectType.SPEED))
                        this.getServer()
                                .getScheduler()
                                .scheduleAsyncRepeatingTask(this,
                                        new Runnable() {

                                            public void run() {
                                                if (number != -1) {
                                                    if (number != 0) {
                                                        p.setHealth(p
                                                                .getHealth() + 1);
                                                        number--;
                                                    } else
                                                        p.sendMessage(ChatColor.RED
                                                                + "You are no longer healing");
                                                    number--;
                                                }
                                            }
                                        }, 0L, 20L);
                }
            }

        }
    }

What do you mean by reset? Do you mean cancel the task?

Also Never use an async task to access the BukkitAPI. The Bukkit API does not support async tasks, so your setHealth and sendMessage lines may not get triggered. Change it to a Sync repeating task.
