Hello, this project is a spigot plugin that supports multi-versionning with the NMS API.

├── core              This is the main module of the project where the cross-version
│                     code is handled.
├── 1_13, 1_14        These are the version-specific modules.

The version loading system is already implemented in the core module.

To build the plugin, you just have to launch the task :core:createPluginJar. Your plugin will be built in the core/build/libs directory.

Renaming the packages is pretty straight-forward but needs a bit of time. First, rename all the packages containing ch.skyfy.plugin by the package you want.

After you've done this, you can edit the core/src/main/resources/plugin.yml to match the new package name.

Create a folder named after your version (ex : 1_13 for 1.13.X, 1_14 for 1.14.X, etc...).

Then, go into the settings.gradle file, and add at the end :

include ':version' // Replace version with the name of the folder you've just created

In the folder of the module, create a build.gradle file and fill it with the following content :

dependencies {
    // Replace VERSION with the version you want and make sure that you've run
    // BuildTools for this version before going further.
    implementation name: 'craftbukkit-1.16.5-R0.1-SNAPSHOT'
    implementation name: 'spigot-api-1.16.5-R0.1-SNAPSHOT'
}

Then, create a src/main/java/ folder inside the module, that's where you'll put your code.

Create the MODULE/src/main/java/your/package/VERSION/VersionLoader.java file, replacing MODULE with the name of the module you've created, and VERSION with the name of the version you want, following the spigot-api naming convention. (ex : v1_13_R1, v1_12_R2, etc...)

Make the VersionLoader class implement the IVersionLoader interface.

Then, create the load() method and register the version-specific code in it. And you're good to go !
