Configurable ItemStacks don't work?

Hey all,
Like the title says, it's not working :/
Sorry for not using spoilers! I'm on Ipad right now

Source code of command class:
package me.bramhaag.hidehub.HideHub;
import java.util.ArrayList;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.Server;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.PlayerInventory;
import org.bukkit.inventory.meta.ItemMeta;
public class Commands implements CommandExecutor {
public HideHub plugin;

//commands
@Override
public boolean onCommand(CommandSender sender, Command cmd,
String args2, String[] args) {

//Vanish item command
if (sender instanceof Player) {
Player p = (Player) sender;
if (cmd.getName().equalsIgnoreCase("clock")) {
if (p.hasPermission("hh.give.vi")) {

//Itemstack Vanish item
ItemStack vanish = new ItemStack(Material.getMaterial(plugin.getConfig().getString("vanish-item")));
ItemMeta vanishmeta = vanish.getItemMeta();

//Name and Lore
ArrayList<String> lore = new ArrayList<String>();
vanishmeta.setDisplayName(ChatColor.GREEN + " ---Vanish Clock---");
lore.add(ChatColor.STRIKETHROUGH + "------------------");
lore.add(ChatColor.WHITE + " Right click to vanish");
lore.add(ChatColor.WHITE + " all the players");
lore.add(ChatColor.STRIKETHROUGH + "------------------");
vanishmeta.setLore(lore);
vanish.setItemMeta(vanishmeta);

//Add To Inventory
p.getInventory().addItem(new ItemStack(vanish));

//Messages
String message = plugin.getConfig().getString("give-vanish-item");
message.replace("{player}",p.getName());
p.sendMessage(message);



}
}
}
return false;
}
}

Error if run the command:

Learn to read stacktraces, as the error points to line 33 of your class. We need to see code tags not spoilers.... How did you even paste the code and error from ipad?

 

You can not use unsupported builds here.. I think you should be on the Spigot forum, not here.
But the problem is that the item is not a real item.

 

Locked. Unofficial builds are not supported here.
