Pure

Pure is a World Generator Bukkit plugin, planning to become a Sponge plugin, too.

It was created to provide a simple way to use Minecraft Vanilla world generation on non-Vanilla based Minecraft Server softwares like Glowstone.

In the end, this will allow multiple cool things:

• Allow the use of the Vanilla world generator in a non-Vanilla context
• Keep the previous version World Generator for your Minecraft map while updating to the next version
• Have multiple maps with different Minecraft versions World Generators on the same server

It is written in Kotlin. The parts interacting with obfuscated Minecraft classes are in Java for clarity.

How

The plugin downloads the required Minecraft Server jar files from their official repository on Amazon S3. It then remaps the jar file content so that it doesn't clash with other versions. Finally, it loads the jar file and use its obfuscated content to provide a Bukkit World Generator.

For now, I don't know how to do the same with Sponge.

Repository

Libraries required for this to work are stored into another git repository to prevent bloating this repository's git history.

To recursively clone this repository and its submodule, use the following command:

git clone --recursive https://github.com/Ribesg/Pure.git

Using the mvn command afterward will directly compile a working Pure.jar under target.

The history of this repository has been cleaned when it has been separated from its libraries. The old history can be found in the Pure-old repository.

Credits

Pure is based on original work by coelho mostly on VanillaGenerator and a little on VanillaNMS. I first started by implementing a clean way to handle Minecraft Server jar files, then basically copy the implementation of Minecraft 1.7.10 found in VanillaGenerator. I understood it, commented it, enhanced it and fixed it. I added generated chests support among other things.
