Minecraft Gravity API and Paper Plugin Development Basics

What Is the Bukkit API?

The Bukkit API is the programming interface used to create Minecraft server plugins. Paper implements and extends the Bukkit API with additional features. You write plugins in Java (or Kotlin) using Maven or Gradle.

Setting Up Your Project

Use Maven or Gradle with the Paper dependency. The PaperMC documentation at docs.papermc.io has the official setup guide with current dependency coordinates.

Your First Plugin Class

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {
        getLogger().info("MyPlugin enabled!");
    }
    @Override
    public void onDisable() {
        getLogger().info("MyPlugin disabled!");
    }
}

Event Listeners

Plugins respond to game events by implementing the Listener interface and annotating methods with @EventHandler. Listen for player joins, block breaks, mob deaths, and hundreds of other events.

Commands

Register commands in plugin.yml and handle them by implementing CommandExecutor. Commands receive the sender, the command object, and the arguments as a String array.

Testing on CraftNodes

Build your plugin JAR with Maven or Gradle, upload it to your CraftNodes server's plugins folder via SFTP, and reload with /reload or a full restart. View errors in the console output.
