    What function? What does it do? Why can't a plugin do it?
    As you are in a place for plugin development, not changing the original jar

    I'm not writing a mod as a separate plugin, I want to change the classes of mincraft client and recompile them, I mean patch the original client, but then I have to decompile -> change what I need (whether it's a variable or a new function, anything) and -> compile -> start minecraft

    I know people who do this, but how do they recompile their classes after making changes so that the class compiles without errors.

    Bukkit is for plugins, not for mods, certainly not for patching the normal jar.
