Hello, my plugin isn't working and when I try to perform the command /acceptrules an internal error occurs. This is my Code : Code (Text): package me.officialnl.main; import net.md_5.bungee.api.ChatColor; import org.bukkit.Location; import org.bukkit.command.Command; import org.bukkit.command.CommandExecutor; import org.bukkit.command.CommandSender; import org.bukkit.entity.Player; import org.bukkit.event.EventHandler; import org.bukkit.event.player.PlayerLoginEvent; import org.bukkit.plugin.java.JavaPlugin; public class Main extends JavaPlugin{ public void onEnable(){ getLogger().info("BizzCraft First Join plugin enabled"); } public void onDisable(){ getLogger().info("BizzCraft First Join plugin disabled"); } private void teleportInWorld(Player p, int x, int y, int z){ p.teleport(new Location(p.getWorld(), x, y, z)); } @EventHandler public void PlayerJoin(PlayerLoginEvent event) { Player p = event.getPlayer(); if(!p.hasPlayedBefore()) { teleportInWorld(p, 149,33,170); p.sendMessage("You have to accept the rules before you can play"); } } public boolean onCommand(CommandSender s, Command cmd, String label, String[] args){ if(cmd.getName().equalsIgnoreCase("acceptrules")){ if (!(s instanceof Player)){ getLogger().info("Only players are allowed to use this command"); return true; } Player p = (Player) s; p.performCommand("help"); p.sendMessage(ChatColor.GREEN + "You accepted the rules"); } return false; } } And this is the Error I get when I try to perform the /acceptrules command : Code (Text): [02:39:05 INFO]: OfficialNL issued server command: /acceptrules [02:39:05 ERROR]: null org.bukkit.command.CommandException: Unhandled exception executing command 'acceptrules' in plugin Particles v1.0 at org.bukkit.command.PluginCommand.execute(PluginCommand.java:46) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:140) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at org.bukkit.craftbukkit.v1_11_R1.CraftServer.dispatchCommand(CraftServer.java:629) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PlayerConnection.handleCommand(PlayerConnection.java:1286) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PlayerConnection.a(PlayerConnection.java:1146) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PacketPlayInChat.a(SourceFile:37) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PacketPlayInChat.a(SourceFile:9) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PlayerConnectionUtils$1.run(SourceFile:13) [craftbukkit.jar:git-Bukkit-2ad21b8] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [?:1.8.0_111] at java.util.concurrent.FutureTask.run(Unknown Source) [?:1.8.0_111] at net.minecraft.server.v1_11_R1.SystemUtils.a(SourceFile:46) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.MinecraftServer.D(MinecraftServer.java:695) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.DedicatedServer.D(DedicatedServer.java:360) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.MinecraftServer.C(MinecraftServer.java:650) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.MinecraftServer.run(MinecraftServer.java:554) [craftbukkit.jar:git-Bukkit-2ad21b8] at java.lang.Thread.run(Unknown Source) [?:1.8.0_111] Caused by: java.lang.NoClassDefFoundError: net/md_5/bungee/api/ChatColor at me.officialnl.main.Main.onCommand(Main.java:45) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[craftbukkit.jar:git-Bukkit-2ad21b8] ... 15 more Caused by: java.lang.ClassNotFoundException: net.md_5.bungee.api.ChatColor at java.net.URLClassLoader.findClass(Unknown Source) ~[?:1.8.0_111] at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:77) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:62) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at java.lang.ClassLoader.loadClass(Unknown Source) ~[?:1.8.0_111] at java.lang.ClassLoader.loadClass(Unknown Source) ~[?:1.8.0_111] at me.officialnl.main.Main.onCommand(Main.java:45) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[craftbukkit.jar:git-Bukkit-2ad21b8] ... 15 more
You're trying to use net.md_5.bungee.api.ChatColor on a Bukkit only server. That class isn't available, so there's an error. Fixes would be either using Spigot server, or using org.bukkit.ChatColor
I added the org.bukkit.chatcolor and I'm still having errors, this is my error: Code (Text): 03:39:14 INFO]: OfficialNL issued server command: /acceptrules [03:39:14 ERROR]: null org.bukkit.command.CommandException: Unhandled exception executing command 'acceptrules' in plugin Particles v1.0 at org.bukkit.command.PluginCommand.execute(PluginCommand.java:46) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:140) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at org.bukkit.craftbukkit.v1_11_R1.CraftServer.dispatchCommand(CraftServer.java:629) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PlayerConnection.handleCommand(PlayerConnection.java:1286) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PlayerConnection.a(PlayerConnection.java:1146) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PacketPlayInChat.a(SourceFile:37) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PacketPlayInChat.a(SourceFile:9) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.PlayerConnectionUtils$1.run(SourceFile:13) [craftbukkit.jar:git-Bukkit-2ad21b8] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [?:1.8.0_111] at java.util.concurrent.FutureTask.run(Unknown Source) [?:1.8.0_111] at net.minecraft.server.v1_11_R1.SystemUtils.a(SourceFile:46) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.MinecraftServer.D(MinecraftServer.java:695) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.DedicatedServer.D(DedicatedServer.java:360) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.MinecraftServer.C(MinecraftServer.java:650) [craftbukkit.jar:git-Bukkit-2ad21b8] at net.minecraft.server.v1_11_R1.MinecraftServer.run(MinecraftServer.java:554) [craftbukkit.jar:git-Bukkit-2ad21b8] at java.lang.Thread.run(Unknown Source) [?:1.8.0_111] Caused by: java.lang.NoClassDefFoundError: net/md_5/bungee/api/ChatColor at me.officialnl.main.Main.onCommand(Main.java:45) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[craftbukkit.jar:git-Bukkit-2ad21b8] ... 15 more Caused by: java.lang.ClassNotFoundException: net.md_5.bungee.api.ChatColor at java.net.URLClassLoader.findClass(Unknown Source) ~[?:1.8.0_111] at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:77) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:62) ~[craftbukkit.jar:git-Bukkit-2ad21b8] at java.lang.ClassLoader.loadClass(Unknown Source) ~[?:1.8.0_111] at java.lang.ClassLoader.loadClass(Unknown Source) ~[?:1.8.0_111] at me.officialnl.main.Main.onCommand(Main.java:45) ~[?:?] at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) ~[craftbukkit.jar:git-Bukkit-2ad21b8] ... 15 more
This is my plugin.yml Code (Text): name: Particles main: me.officialnl.main.Main version: 1.0 description: FirstJoinEvent commands: acceptrules:
Then you have either failed to export of failed to restart your server correctly, because if net.md_5.bungee.api.ChatColor is nowhere in your files, you will never get this error.
"ctrl + f" for "net.md_5.bungee.api.ChatColor" in your project and replace it with the Bukkit API one. If you're still getting the error, you're still using it somewhere within your project. You most likely are still importing it.
I copied your code and removed line 3 and re imported color from bukkit, works like a charm buddy, The ticket is solved it actually was as early as Redrield´s comment.
Well, did you fix your plugin.yml (I nearly wrote pom.xml xD) and did you register the event in the first place? Even if the listener is in the main class, you still need to register it.
Hello, thank you for all the help.

It still apears youre using the wrong import, try completely deleting the current import, and reimport. Maybe youre complining to the wrong place? Not sure what would keep causing this issue Also, you need to register your events
