Hi there, I'm trying to run forge 1.7.10 from command line. I've copied all of the required libraries to a single folder, and I'm using the following code to start it:

 

java -Xmx3000m -Djava.library.path=%APPDATA%\.minecraft\versions\1.7.10-Forge10.13.2.1291\1.7.10-Forge10.13.2.1291.jar -cp %APPDATA%\.ssmc\lib\* net.minecraft.launchwrapper.Launch --session (Default) --username testuser --tweakClass cpw.mods.fml.common.launcher.FMLTweaker --version 1.7.10 --assetsDir %APPDATA%\.minecraft\assets\ --gameDir %APPDATA%\.minecraft --accessToken (Default) --assetIndex 1.7.10 --uuid

 

However, it starts to load the tweak class, but I'm getting the following error:

I've checked it on google, and also in the forum too, and found out that I should delete every mod unrelated to this version, but the problem is that it's a clean install, the mods folder is empty. I've tried it with java8 and java7 too, with legacy java fixer and without it, but I have no idea for now. Anyone can help?

 

 

EDIT: Fixed it. Cause of the problem was I messed up locations of libs and other paths.

The way you are launching the game is atrocious.

Why are you doing it manually like that?

Use the installer and normal launchers. You're missing minecraft itself.
