Recraft is a Gradle Plugin I made especially for ModernDisguise my library. It allows you to easily create 2 classes of the same class, once remapped for paper and once for spigot. Also adds a prefix before the class name to avoid conflicts.

Add this repo to your plugin repositories:

pluginManagement {
    repositories {
        gradlePluginPortal() // Incase you use other plugins
        maven("https://repo.gravemc.net/releases") // GraveMC's Maven Repository
    }
}

and then add this to your plugins block:

plugins {
    id("dev.iiahmed.recraft") version "1.0.2"
}

In your build.gradle.kts file, After you add the plugin, you can use the recraft block to configure it:

recraft {
    // Set The Minecraft version you are targeting
    minecraftVersion.set("1.20.4")

    // List of packages to include for prefixing/relocation
    targetedPackages.set(listOf(
        "dev/iiahmed/disguise/vs",
        "org/some/dependency"
    ))

    // OPTIONAL:
    // The prefix to use for the remapped classes
    paperPrefix.set("P")
    spigotPrefix.set("S")

    // Set the pattern for the jar file (starting from the `build` directory)
    jarFilePattern.set("libs/${project.name}-${project.version}.jar") // The default is "libs/${project.name}.jar"
}

The plugin supports Minecraft versions from 1.17.1 to 1.21.10, and it will automatically download the necessary mappings for you.

To add support for a new version, it's not as complicated. You need to add the mappings to the util/MappingFetcher object, and then update 2 maps.

First Map is the versionToHash map, you can get the hash by visitng the Mojang Versions page, and then find the version you want to add, and open the URL from 'url' field.

then in that page you can find the hash in the 'downloads' field under 'server_mappings'.

The url should look like this: https://piston-data.mojang.com/v1/objects/<hash>/server.txt Just get the hash and add it to the map along with the version you want to add.

The second map is the versionToCommit map, you can get the hash by visiting the SpigotMC Versions page, and find a commit that matches the version you want to add. after you find the commit, just copy the hash and add it to the map along with the version you want to add.
