Hi, I'm trying to add an external jar to eclipse and everything works perfect, but when I put the mod in minecraft it says that it does not find the class of the jar that it exports, and look for how to do it, I saw that many say that it uses "shading" but already I did it and it does not work or I do not know if I do something wrong, I am new to this and I know it is wrong and it is not recommended but I would like someone to help me on how to do this and if it is possible to give me examples, I only have a problem with this and thanks.
