PaperMC API Maven - Java

Introduction

PaperMC is a high-performance Minecraft server implementation based on the Spigot/Bukkit APIs. It aims to improve server performance and offer additional features that enhance gameplay for server owners and players.

The PaperMC API allows developers to extend and customize their Minecraft servers using Java. By adding the PaperMC API Maven dependency to your Java project, you can access various Minecraft-specific functionalities and build plugins or mods.

This guide will walk you through the process of setting up a Maven project with the PaperMC API, explaining the necessary steps and providing code snippets along the way.

Prerequisites

Before getting started, make sure you have the following:

1. JDK (Java Development Kit) installed on your system.
2. Maven installed on your system.
3. A basic understanding of Java programming.

Setting Up a New Maven Project

To set up a new Maven project with the PaperMC API, follow these steps:

1. Create a new directory for your project.
2. Open a terminal or command prompt and navigate to the project's directory.
3. Run the following command to initialize a new Maven project:

mvn archetype:generate -DgroupId=com.example -DartifactId=papermc-api-demo -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

This command will create a new Maven project with the specified group ID (com.example) and artifact ID (papermc-api-demo).

4. Open the pom.xml file in the project's root directory and add the PaperMC API Maven dependency:

<dependencies>
    <dependency>
        <groupId>io.papermc</groupId>
        <artifactId>paper-api</artifactId>
        <version>1.17.1-R0.1-SNAPSHOT</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

Make sure to replace the version number (1.17.1-R0.1-SNAPSHOT) with the latest version available.

Developing with PaperMC API

With your Maven project set up, you can start developing with the PaperMC API. Here's a simple example to get you started:

1. Create a new Java class (ExamplePlugin.java) in the src/main/java/com/example directory.
2. Add the following code to the ExamplePlugin class:

package com.example;

import org.bukkit.plugin.java.JavaPlugin;

public class ExamplePlugin extends JavaPlugin {

    @Override
    public void onEnable() {
        getLogger().info("ExamplePlugin enabled!");
    }

    @Override
    public void onDisable() {
        getLogger().info("ExamplePlugin disabled!");
    }
}

This code defines a basic Bukkit plugin class that extends JavaPlugin. The onEnable and onDisable methods are called when the plugin is enabled and disabled, respectively.

3. Build the Maven project by running the following command in the project's root directory:

mvn package

This command will compile your Java code and generate a JAR file in the target directory.

4. Copy the generated JAR file (papermc-api-demo-1.0-SNAPSHOT.jar) to the plugins folder of your Minecraft server.

5. Start or restart your Minecraft server, and you should see the "ExamplePlugin enabled!" message in the server console.

Conclusion

In this guide, you've learned how to set up a new Maven project with the PaperMC API and develop a simple Minecraft plugin using Java. The provided code snippets should help you get started with customizing and extending your Minecraft server.

Remember to refer to the PaperMC API documentation for more details on the available classes, methods, and events you can leverage when developing your plugins. Happy coding!
