Green coffee beans aren't natural, you have to make them. First youre gonna need a coffee cherry. Those shouldn't be to hard to find in a single player world, but a lot more difficult in a multiplayer world. For multiplayer use a trade portal or explore the entire place.

After you got the cherry you'll need a press, where you press it into a green coffee bean. You can then use an electric stove to make a roasted coffee bean, and then coffee with a bucket of water and a mug.
