Loading Forge without repacking minecraft.jar

[PlayerWithoutName]

Hello,

 

I'm making a launcher for my modpack and i want to launch Minecraft with Forge without repacking minecraft.jar, do You know how MultiMC loads mods from instMods or TechnicLauncher loads modpack.jar?

 

Thanks for help.

MultiMC repacks the jar

Technic's ModPack.jar IIRC is the entire mojang codebase {all of Minecraft.jar}

It can be done better, by simple adding Forge to the classpath BEFORE minecraft.jar

But what ever, people can't seem to figure that out.

But how? When i execute it like that:

 

"java -Xms1G -Xmx1G -cp \".\\starchasers\\.minecraft\\bin\\modpack.jar;.\\starchasers\\.minecraft\\bin\\minecraft.jar;.\\starchasers\\.minecraft\\bin\\jinput.jar;.\\starchasers\\.minecraft\\bin\\lwjgl.jar;.\\starchasers\\.minecraft\\bin\\lwjgl_util.jar\" -Djava.library.path=.\\starchasers\\.minecraft\\bin\\natives net.minecraft.client.Minecraft " + MainWindow::explode( MainWindow::session , ':' , 2 ) + " " + sessionid;

 

it throws me: Exception in thread "main" java.langSecurityException: class "sq"'s signer information does not match signer information on other classes in the same package. ;( I think it's something about META-INF folder.

Kill the meta-inf folder in minecraft.jar
