Give splash potion and potion

Hi guys,

I would create 2 methods for create my potion.
Actuallay, I use ItemBuilder class -> https://www.spigotmc.org/threads/util-itembuilder-manage-items-easily.48397/

But I can't create potion with this method.
I create 2 method for 2 potion type (splash or not), but with the splash potion I can't choose the time for duration.

Code:

/Can use the duration
    public ItemBuilder setPotion(PotionEffectType effect, int level, int duration) {
        PotionMeta meta = (PotionMeta) is.getItemMeta();
        meta.addCustomEffect(new PotionEffect(effect, (duration * 20), (level - 1)), true);
        is.setItemMeta(meta);
        return this;
    }

    //Not here
    public static ItemStack setPotion(PotionType effectPotion, int level){
        Potion splash = new Potion(effectPotion, level);
        splash.setSplash(true);

        ItemStack potion = splash.toItemStack(1);
        ItemMeta meta = potion.getItemMeta();
        potion.setItemMeta(meta);
        return potion;
    }

Can you help me ?

 

up ?
