Okay. I'm trying to decompile minecraft 1.4.7 using mcp forge. But whenever I try to, i get the error that says i'm missing certain classes. As far as I know, this issue occurs with every mc version before 1.6. I just want to decompile 1.4.7 again so I can finish up my coding for my mod, reobfuscate it, update it to 1.7, and then write some files for my mod based off a few 1.4 files. But in order accomplish this list I need to decompile 1.4 which I can't do because of this error
