Missing files from .bat startup

Hey Everyone, I'm trying to set up an rlcraft server for some of my friends but when running the .bat file it appears with this. Just wondering if there was any way to fix this?

Apologies if this isn't the right thread, I wasn't super sure.

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
