Need to reset my 1.12.2 forge server

[StormDeBoi]

So aparently i've made my first forge server and everything is going fine. I've had problems such as the server being Vanilla and the Java version needing to be updated, but i solved those problems just fine. The thing is that i need to generate the world again or else the only thing that will appear are the mobs, making items that need modded minerals impossible to be crafted. Is there any way to regenerate the world? i don't mind if it generates a completely new one.

still need help.
