I Just got a new server, and after i've installed forge, I try to start up the server but it gives me an error: 

We appear to be missing one or more essential library files.

You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch

I used the forge installer (not universal), I've tried reinstalling it multiple times but it just won't work

 

Please help,

Thanks in advance.

Please post your debug.log file.

Also, make sure you read up on all the mods you install, it's possible one of them requires another mod/library that you did not install.

Here is the log:

Also, I looked at all the mods and looked if one of them needs another mod to run, but none of them did.
