forgeClient in launcher

[Lammendam]

hello, i'm making my own launcher, that should start 1.7.10 client with forge.

how can i do this? i have tried to load class "net.minecraft.launchwrapper.Launch.class" from LaunchWrapper.jar but get an exception:

java.lang.IllegalAccessException: Class net.launcher.run.MCLauncher can not access a member of class net.minecraft.launchwrapper.Launch with modifiers "private"

i'm getting a headache from an endless search in google, but cannot find anything, except installing and using forge+mods on completed launchers.

maybe i need to tell wrapper some args or something...

 

thanks in advance

Don't.

1.7.10 is no longer supported on this forum.

Take the hint. Just use an available launcher.
