java.lang.NullPointerException

Help I can't figure out how to fix this error. This is my first plugin.

Code:

package me.jblade.kits;



import org.bukkit.ChatColor;

import org.bukkit.Material;

import org.bukkit.command.Command;

import org.bukkit.command.CommandSender;

import org.bukkit.enchantments.Enchantment;

import org.bukkit.entity.Player;

import org.bukkit.inventory.ItemStack;

import org.bukkit.plugin.java.JavaPlugin;



public class Test extends JavaPlugin {

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)

  {

Player p = (Player)sender;


if(cmd.getName().equalsIgnoreCase("pvp")){

p.sendMessage(ChatColor.AQUA + "You have obtained the PvP kit!");

ItemStack dsword = new ItemStack(Material.DIAMOND_SWORD);

dsword.addEnchantment(Enchantment.DAMAGE_ALL, 1);

p.getInventory().addItem(dsword);

p.getInventory().setHelmet(new ItemStack(Material.IRON_HELMET));

p.getInventory().setChestplate(new ItemStack(Material.IRON_CHESTPLATE));

p.getInventory().setLeggings(new ItemStack(Material.IRON_LEGGINGS));

p.getInventory().setBoots(new ItemStack(Material.IRON_BOOTS));

for (ItemStack item : p.getInventory().getContents()) {

if (item == null) {

p.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));

}

}






}


returnfalse;


  }



}

 

@jblade123 This is the wrong forum, put it into the Bukkit development section, and when you move it add the error you get in console.
