Forge decompileation error

[JacobYarbrough13]

I am a forge modder and when I try to start a new mod, I download the forge version 9.11.1.953 src and then put it in a folder on my desktop, when I click the install batch file, it goes well until the minecraft.jar download then it gives me an error that says "Download of minecraft_server.1.6.4.jar failed hash check, deleting abcf286a14f7a

Use the gradle system with 964, Mojang broke the old stuff.

[JacobYarbrough13]

is the code the same as the 9.11.1.953?

Minus modloader support, yes.

But you shouldn't be developing for ModLoader as it's dead.
