How to build your first Minecraft plugin

# Build Your First Minecraft Plugin with Spigot

In this article, I'm going to show you how to build your first Minecraft plugin using the Spigot API. If you've ever wanted to create your own commands, listen to player events, or customize your server, this is the perfect place to start 🚀

Whether you're building a small utility plugin or planning your next big project, understanding the basics will save you countless hours later.

## Why Spigot?

Spigot has been the standard API for Minecraft server development for years. It provides an easy way to interact with the server without modifying Minecraft itself.

Some things you can do with Spigot include:

- Create custom commands
- Listen to player events
- Build custom game mechanics
- Create inventories and GUIs
- Manage permissions
- Interact with worlds and entities

The API is beginner-friendly while still being powerful enough for large production servers.

## Setting up the Project

You'll need:

- Java 8 (recommended for Minecraft 1.8.8)
- IntelliJ IDEA (or your favorite IDE)
- Maven
- Spigot API

Your `pom.xml` should include the Spigot dependency:

```xml
<repositories>
<repository>
<id>spigot-repo</id>
<url>https://hub.spigotmc.org/nexus/content/repositories/snapshots/</url>
</repository>
</repositories>

<dependencies>
<dependency>
<groupId>org.spigotmc</groupId>
<artifactId>spigot-api</artifactId>
<version>1.8.8-R0.1-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
</dependencies>
```

## Creating the Main Class

Every plugin starts with a class that extends `JavaPlugin`.

```java
public class ExamplePlugin extends JavaPlugin {

@Override
public void onEnable() {
getLogger().info("Hello world!");
}

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

Think of `onEnable()` as the entry point of your plugin. This is where you'll register commands, events, configuration files, and scheduled tasks.

---

## Creating `plugin.yml`

Every plugin also requires a `plugin.yml` file.

```yaml
name: ExamplePlugin
version: 1.0
main: com.example.ExamplePlugin
author: YourName

commands:
hello:
description: Says hello.
```

Without this file, Spigot won't recognize your plugin.

---

## Creating Your First Command

Let's create a simple command called `/hello`.

```java
public class HelloCommand implements CommandExecutor {

@Override
public boolean onCommand(CommandSender sender,
Command command,
String label,
String[] args) {

sender.sendMessage("Hello from my first plugin!");
return true;
}
}
```

Now register it inside `onEnable()`.

```java
@Override
public void onEnable() {
getCommand("hello").setExecutor(new HelloCommand());
}
```

Start the server and type:

```text
/hello
```

You should receive:

```text
Hello from my first plugin!
```

🎉 Congratulations! You've just created your first Minecraft command.

---

## Listening to Events

Commands are useful, but events are where the fun begins.

Let's welcome players whenever they join.

```java
public class PlayerListener implements Listener {

@EventHandler
public void onJoin(PlayerJoinEvent event) {
event.getPlayer().sendMessage("Welcome to the server!");
}
}
```

Register the listener.

```java
@Override
public void onEnable() {
getServer().getPluginManager().registerEvents(
new PlayerListener(),
this
);
}
```

Now every player that joins will receive your custom message.

---

## Organizing Your Project

As your plugin grows, it's important to keep everything organized.

A common structure looks like this:

```text
src/
└── main/
├── java/
│ └── com/example/plugin/
│ ├── ExamplePlugin.java
│ ├── commands/
│ ├── listeners/
│ ├── managers/
│ ├── utils/
│ └── menus/
└── resources/
└── plugin.yml
```

Keeping your code modular will make future features much easier to maintain.

---

## What's Next?

Once you're comfortable with commands and events, you can explore more advanced topics like:

- Custom inventories
- Scoreboards
- Configuration files
- Scheduled tasks
- NPCs
- Packet manipulation
- NMS development
- Custom game modes

These are the building blocks behind many popular Minecraft servers.

## That's it!

Building Minecraft plugins is one of the best ways to learn Java while creating something players can actually interact with.

Start small, experiment often, and don't be afraid to break things—that's how you'll learn the most.

Happy coding! 🚀
