Hi people, i have been doing my best trying to know why I have this error but I cant make it work. I have checked spigot forums, but the solutions for others havent worked for me. I am making a plugin which uses a Ping system, and in a simple command of getting a players ping i get this error: Spoiler: Error Code (Text): [18:16:46 INFO]: woarth issued server command: /ping [18:16:46 WARN]: java.lang.ClassNotFoundException: org/bukkit/craftbukkit//entity/CraftPlayer [18:16:46 WARN]: at java.lang.Class.forName0(Native Method) [18:16:46 WARN]: at java.lang.Class.forName(Unknown Source) [18:16:46 WARN]: at me.woarth.PingPlugin.Commands.Ping.getPlayerPing(Ping.java:32) [18:16:46 WARN]: at me.woarth.PingPlugin.Commands.Ping.onCommand(Ping.java:66) [18:16:46 WARN]: at org.bukkit.command.PluginCommand.execute(PluginCommand.java:44) [18:16:46 WARN]: at org.bukkit.command.SimpleCommandMap.dispatch(SimpleCommandMap.java:141) [18:16:46 WARN]: at org.bukkit.craftbukkit.v1_11_R1.CraftServer.dispatchCommand(CraftServer.java:649) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.PlayerConnection.handleCommand(PlayerConnection.java:1337) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.PlayerConnection.a(PlayerConnection.java:1172) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.PacketPlayInChat.a(PacketPlayInChat.java:45) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.PacketPlayInChat.a(PacketPlayInChat.java:1) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.PlayerConnectionUtils$1.run(SourceFile:13) [18:16:46 WARN]: at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [18:16:46 WARN]: at java.util.concurrent.FutureTask.run(Unknown Source) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.SystemUtils.a(SourceFile:46) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.MinecraftServer.D(MinecraftServer.java:739) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.DedicatedServer.D(DedicatedServer.java:399) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.MinecraftServer.C(MinecraftServer.java:675) [18:16:46 WARN]: at net.minecraft.server.v1_11_R1.MinecraftServer.run(MinecraftServer.java:574) This is the code: Spoiler: Code Code (Text): @SuppressWarnings({ "unused", "rawtypes" }) public static int getPlayerPing(Player player) { try { int ping = 0; Class craftPlayer = Class.forName("org.bukkit.craftbukkit." + getServerVersion() + ".entity.CraftPlayer"); Object converted = craftPlayer.cast(player); Method handle = converted.getClass().getMethod("getHandle", new Class[0]); Object entityPlayer = handle.invoke(converted, new Object[0]); Field pingField = entityPlayer.getClass().getField("ping"); return pingField.getInt(entityPlayer); } catch (Exception ex) { ex.printStackTrace(); } return 0; } public static String getServerVersion() { Pattern brand = Pattern.compile("(v|)[0-9][_.][0-9][_.][R0-9]*"); String pkg = Bukkit.getServer().getClass().getPackage().getName(); String version = pkg.substring(pkg.lastIndexOf('.') + 1); if (!brand.matcher(version).matches()) { version = ""; } return version; } Spoiler: Line 32 Code (Text): Class craftPlayer = Class.forName("org.bukkit.craftbukkit." + getServerVersion() + ".entity.CraftPlayer"); Spoiler: Line 66 Code (Text): int ping = getPlayerPing(Bukkit.getPlayer(sender.getName())); The plugin is using spigot 1.11 version and in a 1.8 server this ping system works fine.
