Ensure that you have at least Java 16.

Make sure that you have installed the latest version of TerraformGenerator.
To do that, stop your server and upload the jar file to the plugins directory of your server. Afterwards, can you start your server again.

Please note that some server types like CraftBukkit may not work with TerraformGenerator and can result in a crash of your server.
To prevent this do we recommend the usage of either Spigot or PaperMC (The latter one is more recommended).

You can choose between two methods on how to generate the world with TerraformGenerator

1. Turn off the server if it is running
2. Open the bukkit.yml and add the following info to it.

   #
   # NOTE:
   # This section does by default NOT exist in your bukkit.yml
   # You have to add it yourself.
   #
   worlds:
       <world_name>: # Replace <world_name> with the world name you want to use.
           generator: TerraformGenerator

3. If present delete the folder of the world that you want TerraformGenerator to create.
4. Start your Server again.

This method requires a World-Management plugin to be installed and enabled on your server.
Multiverse has been known to cause a few weird issues. Follow the instructions very precisely. In our example will we use Multiverse-Core. Terraform Generator may work with other World-managers but we won't guarantee it!

1. Make sure you did the steps of the first method before you continue.
2. Make sure that the World-Manager is enabled (Shows up green in the /plugins list).
3. When a World with your selected name already exists, delete it with /mvdelete <world> followed by /mvconfirm
   • Note that this won't work with default worlds and requires a stop of your server and manual deletion of the world!
4. Create the world using /mvcreate <world> normal -g TerraformGenerator where <world> is the name of the world you defined in the first method

It's recommended but not necessary to pre-generate your world using a plugin.
Please take a look at our FAQ for a list of plugins for pre-generating Worlds.
