Paper 1.12.2. java.lang.NullPointerException: null at org.kokinsgrief.fun.kokinsblack.KokinsBlack.onEnable(KokinsBlack.java:16) ~[?:?]

[/u/ExistingArtichoke989]

My plugin doesn't work on Paper 1.12.2. The error that appears in the console:

java.lang.NullPointerException: null at org.kokinsgrief.fun.kokinsblack.KokinsBlack.onEnable(KokinsBlack.java:16) ~[?:?]

Plugin code:

package org.kokinsgrief.fun.kokinsblack; import org.bukkit.Bukkit; import org.bukkit.ChatColor; import org.bukkit.command.Command; import org.bukkit.command.CommandExecutor; import org.bukkit.command.CommandSender; import org.bukkit.entity.Player; import org.bukkit.plugin.java.JavaPlugin; public final class KokinsBlack extends JavaPlugin { @Override public void onEnable() { getCommand("black").setExecutor(new BlackCommand()); getCommand("unblack").setExecutor(new UnblackCommand()); } private class BlackCommand implements CommandExecutor { @Override public boolean onCommand(CommandSender sender, Command command, String label, String[] args) { if (!(sender instanceof Player)) { sender.sendMessage("This command can only be executed by a player."); return true; } if (!sender.hasPermission("kokinsblack.black")) { sender.sendMessage(ChatColor.RED + "You do not have permission to use this command."); return true; } if (args.length != 1) { sender.sendMessage("Usage: /black <player>"); return true; } Player target = Bukkit.getPlayer(args[0]); if (target == null) { sender.sendMessage("Player not found."); return true; } target.setPlayerListName(ChatColor.BLACK + target.getName()); target.setMaxHealth(4.0); target.setHealth(4.0); sender.sendMessage("Player " + target.getName() + " is now blacklisted."); return true; } } private class UnblackCommand implements CommandExecutor { @Override public boolean onCommand(CommandSender sender, Command command, String label, String[] args) { if (!(sender instanceof Player)) { sender.sendMessage("This command can only be executed by a player."); return true; } if (!sender.hasPermission("kokinsblack.unblack")) { sender.sendMessage(ChatColor.RED + "You do not have permission to use this command."); return true; } if (args.length != 1) { sender.sendMessage("Usage: /unblack <player>"); return true; } Player target = Bukkit.getPlayer(args[0]); if (target == null) { sender.sendMessage("Player not found."); return true; } target.setPlayerListName(target.getName()); target.setMaxHealth(20.0); target.setHealth(20.0); sender.sendMessage("Player " + target.getName() + " is no longer blacklisted."); return true; } } }
