Duplicate of #274 ?

I'm new to the project but got it working in a linux VM no problem (lubuntu 18.10). I think your problem is "<New_World>" should be replaced with the name of existing save. So far as I'm aware this project doesn't support generating new worlds.

EDIT:
I left the save file in ~/.minecraft/saves/ rather than copying to the hematite director, which may have some thing to do with it.
