i've wrote my own small launcher, also as parser of .json file, i'm parsing all lib and flags, trying to launch minecraft with forge (vanilla is launching, if i'm just giving to parser vanilla .json - everything is ok), but there is no main class, i searched manually in 1.7.10.jar file (folder net/minecraft does not have folder launchwrapper), i tried to reinstall minecraft, tried to reinstall forge, this class is still missing (if i'm manually changing it to default minecraft main class - it launches vanilla and also ignoring flag about class tweaking), any ideas? don't think my code needs to be here, or error text (code are long and complicated(but works), error is short and simple)
