Error, need help ;(

Im getting this error, basically I'm making a plugin when you do /destroyer it gives you a diamondsword with fire aspect and sharpness, and it also adds a particle effect when you initiate the command, the effect is potion break, I don't know what the error is? but here is the code:

Code:java

package me.PokeMasterBrobee.FuktPvP;
 
import java.util.Arrays;
import java.util.logging.Logger;
 
import org.bukkit.ChatColor;
import org.bukkit.Effect;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.java.JavaPlugin;
 
public class FuktPvP extends JavaPlugin{
    public static Logger logger = Logger.getLogger("Minecraft");
    public static FuktPvP plugin;
 
    @Override
    public void onEnable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        FuktPvP.logger.info(pdfFile.getName() + pdfFile.getVersion() + "Activated");
    }
 
    @Override
    public void onDisable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        FuktPvP.logger.info(pdfFile.getName() + pdfFile.getVersion() + "Deactivated");
    }
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
        Player player = (Player) sender;
        if(cmd.getName().equalsIgnoreCase("destroyer"));
        ItemStack item = new ItemStack(Material.DIAMOND_SWORD);
        item.addUnsafeEnchantment(org.bukkit.enchantments.Enchantment.FIRE_ASPECT, 5);
        item.addEnchantment(org.bukkit.enchantments.Enchantment.DAMAGE_ALL, 4);
        item.getItemMeta().setDisplayName(ChatColor.RED + "Destroyer");
        item.getItemMeta().setLore(Arrays.asList(ChatColor.GRAY + "This is the destroyer sword"));
        player.playEffect(player.getLocation(), Effect.POTION_BREAK, null);
        player.sendMessage(ChatColor.RED + "You have recieved " + player.getItemInHand().getAmount());
        return false;
    }
 
}

Here is the console:

Edit: never mind, that was incorrect. It doesn't look like you can do that because the data of the Effect is null. You could try this:

Code:java

player.getWorld().playEffect(player.getLocation(), Effect.POTION_BREAK, null);

But it will play the sound too.

 

Thanks its all fixed now Dragonphase
