    4. import org.bukkit.Bukkit;
    5. import org.bukkit.ChatColor;
    6. import org.bukkit.Material;

    8. import org.bukkit.command.CommandExecutor;
    9. import org.bukkit.command.CommandSender;
    10. import org.bukkit.entity.Player;
    11. import org.bukkit.inventory.Inventory;
    12. import org.bukkit.inventory.ItemStack;
    13. import org.bukkit.inventory.meta.ItemMeta;
    14.  
    15. import com.weedlvz.nullpl.NULLpl;
    16.  
    17. public class kit implements CommandExecutor{
    18.  
    19.     NULLpl plugin;
    20.  
    21.     public kit(NULLpl plugin) {
    22.         this.plugin = plugin;
    23.     }
    24.  
    25.     @SuppressWarnings("unused")
    26.     private String tc(String msg) {
    27.         return ChatColor.translateAlternateColorCodes('&', msg);
    28.     }
    29.  
    30.     @Override
    31.     public boolean onCommand(CommandSender sender, Command cmd, String label,
    32.             String[] args) {
    33.         if(cmd.getName().equalsIgnoreCase("kit")){
    34.             Player player = (Player) sender;
    35.             ItemStack kitpvp = new ItemStack(Material.DIAMOND_SWORD);
    36.             ItemMeta kitpvpMeta = kitpvp.getItemMeta();
    37.             kitpvpMeta.setDisplayName(tc("&4&lKit PVP"));
    38.             kitpvp.setItemMeta(kitpvpMeta);
    39.             ItemStack kitfood = new ItemStack(Material.COOKED_BEEF);
    40.             ItemMeta kitfoodMeta = kitfood.getItemMeta();
    41.             kitfoodMeta.setDisplayName(tc("&6&lKit Food"));
    42.             kitfood.setItemMeta(kitfoodMeta);
    43.  
    44.             Inventory inv = Bukkit.createInventory(null, 27,
    45.                     tc("&4&l[NULL] &c&lKits"));
    46.             inv.setItem(11, kitfood);
    47.             inv.setItem(15, kitpvp);
    48.  
    49.             player.openInventory(inv);
    50.  
    51.         }
    52.         return false;
    53.     }

    I dont see whats the problem.
    If i remove the
    Code:java
    1. getCommand("kit").setExecutor(new kit(this));

    Everyting works perfectly fine,If i add the getCommand back it doesnt work i get that error.

    @DerpyLV
    Again, remember to update to 1.11.2

    Something is null on line 105. Is the getCommand line the 105 line? If not, post the whole class/ post that line.
