    Hello, world!

    Sometime ago, I've been searching class, what can change player's skin. I DON'T LIKE PROTOCOLLIB, I'd like to use my own class, my code, what I can change, no APIs, no other plugins, because I like to know ALL of the functions, what I can do, while coding something. I didn't find class, what I need. But in all threads, what I found, I saw: "YOU SHOULD CHANGE GAMEPROFILE". I made it! I made class, what can change your skin! I made t with reflection, to use it on the 1.7 versions of Bukkit, this code will work on many cores, not in only one.

    ALSO, FOR ALL NICE WORK, YOU MUST REGISTER THIS CLASS AS LISTENER IN YOUR onEnable() !

    Code:

    ReflectionUtil class, what I used, from my good friend (We are Russians :3) - https://forums.bukkit.org/threads/lib-reflection-utils.246850/

    This error caused by your core. I'm using Spigot #1543, and in my build class GameProfile has constructor with UUID and String. Your core is elder than mine, and your constructor in GameProfile class is String and String.

    What can u do?

    1. Update your core

    Plugers11 The code is correct I didint test it out fully yet!

    Plugers11 this might cause a problem
    Code:
    Caused by: java.lang.NoSuchMethodException: net.minecraft.util.com.mojang.authli
b.GameProfile.<init>(java.util.UUID, java.lang.String)
