Alright so, I'm trying to run some mods on my server, and I keep getting the following error when I try to run my server.

But it is in the folder. (Im trying to run forge-1.11.2-13.20.0.2228) The forge jar, the vanilla jar, and the libraries that download with forge from the forge official site are all in that folder. I don't exactly understand what i'm doing wrong or how I can fix it. This stuff isn't exactly my forte unfortunately =(. Any help is appreciated.
Figured it out. The jar was called minecraft_server-1.11.2.jar instead of minecraft_server.1.11.2.jar So the - had to be a . //sob
