Hello there,
I'm modding a bit for a while now and I saw in a few tutorials that some people can read the code of the files in "Referenced Libaries" in Eclipse, what'd make modding way easier for me.
Sadly, it isn't the case for me, the only informations I get when I'm trying to open the files are:
"Class File Editor"
"Source not found"
"The JAR file C:\Users\Skrallbadoor\.gradle\cache\forge_gradle_minecraft:user_repo\net\minecraft......................\1.14.2.jar has no source attachment"
"You can attach the source by clicking Attach Source below:"
[Attach Source...]
and then code like:
/ Compiled from ItemEntity.java (version 1.8 : 52.0, super bit)
public class net.minecraft.entity.item.ItemEntity extends net.minecraft.entity.Entity {

On the right side, I have an Outline Window where I can see method and variable names, but thoses aren't what I'm searching for.
Well, now to my question, is there a way to open the jsons in Referenced Libs. and is there a way to get the decompiled code of the class files?
I tried to copy and paste the files, what didint work, that way I can't put the class files into a decompiler. I opened the path where the files are then, and put the class files into a decompiler, but I only got "field_number_letter"s and "function_number_letters"s as code.
I've heard something about a MCP(Minecraft Coder Pack). I'm not sure if I need this to solve my problems and if yes, how to use/install MCP.
