Using MCP in Plugins

ForgeGradle is a Gradle plugin which integrates the MCP workflow into the Gradle build system. It handles setting up the workspace, as well as the re-obfuscation of your plugin.

Megjegyzés

Since ForgeGradle depends on Gradle, the following pages assume you are using Gradle to build your plugin. See Setting Up Gradle to get started.

Configuring ForgeGradle

You can choose between two different types of workspaces:

• Vanilla workspace: Supports plugins for SpongeVanilla and SpongeForge.

• Forge workspace: Supports only plugins for SpongeForge (and not SpongeVanilla).

Megjegyzés

In most cases, the Vanilla workspace can be used for SpongeVanilla and SpongeForge. In some cases, there may be problems on one of the platforms because of changes in the Minecraft code by Forge. Make sure to always test your plugin on both platforms when using MCP.

Choosing a MCP mappings version

To setup a MCP workspace you need to specify the MCP mappings version that will be used to de-obfuscate the Minecraft source with human-readable names. A list of MCP mappings versions is available on the Export page of the MCPBot.

There are stable versions (released from time to time) and daily snapshots which contain the latest name changes. If you do not need a specific name that was added recently, use a stable version (if available for your Minecraft version), otherwise use the latest snapshot version.

Click the button for the version you want to use and select „Use in ForgeGradle”. Then copy the provided version to your Gradle build script (insert it in the snapshot_xxx placeholder below).

Vanilla Workspace

buildscript {
    repositories {
        maven {
            name = 'forge'
            url = 'http://files.minecraftforge.net/maven'
        }
    }

    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.2-SNAPSHOT'
    }
}

plugins {
    id 'org.spongepowered.plugin' version '0.8.1'
    id 'net.minecrell.vanillagradle.server' version '2.2-3'
}

minecraft {
    version = '1.10.2'
    // TODO: Replace with your mappings version, e.g. snapshot_20170120
    mappings = 'YOUR_MAPPINGS_VERSION'
}

Forge Workspace

buildscript {
    repositories {
        maven {
            name = 'forge'
            url = 'http://files.minecraftforge.net/maven'
        }
    }

    dependencies {
        classpath 'net.minecraftforge.gradle:ForgeGradle:2.2-SNAPSHOT'
    }
}

plugins {
    id 'org.spongepowered.plugin' version '0.8.1'
}

apply plugin: 'net.minecraftforge.gradle.forge'

minecraft {
    forgeVersion = '1944' // TODO: Configure Forge build here
    // TODO: Replace with your mappings version, e.g. snapshot_20170120
    mappings = 'YOUR_MAPPINGS_VERSION'
}

Setting Up the Workspace

Every time you update the Minecraft or mappings version, or want to re-import your project, you need to start with setting up your workspace using Gradle. To do that, run the setupDecompWorkspace Gradle task of your project, before importing the project into your IDE:

gradle setupDecompWorkspace

Now you can import your Gradle project, as described in Setting Up Gradle. If your project is already imported, make sure to refresh the Gradle configuration so your IDE can register the new Minecraft dependency.

Building Your Plugin

ForgeGradle automatically configures your plugin to re-obfuscate to Searge mappings when building it so you can run it in production. Make sure to use Gradle’s build task, and not jar directly.
