I am getting the same thing

Are you using forge version 10.13.3.1403-1.7.10?

here is the error

I wanted to "test run forge" before I put all of the mods in my modpack into the mods folder. Minecraft goes to the mojang screen for second before it crashes on me with these errors everytime.

Okay I think I know what is doing in. I was using the LATEST version of forge not the RECOMMENDED version.

Using the recommended version, the game was able to launch.
