I'll help you create that plugin! First, let me verify your setup:

Prerequisites:
1. Java 25 (download from Adoptium or Oracle)
2. Gradle (I can run commands for you in Antigravity!)

If you're using Antigravity, you're all set - I can handle builds directly!

# Download from Adoptium
winget install EclipseAdoptium.Temurin.25.JDK

# Clone the official template (Darkhax/Jared)
git clone https://github.com/Darkhax-Hytale/HytalePluginTemplate.git MyPlugin
cd MyPlugin

        getLogger().info("MyPlugin setting up...");
    }
    
    @Override

Server Boot → setup() → start() → [Running] → shutdown() → Server Stop

    }
    String playerName = args[0];
    String itemId = args[1];
    // Implementation...
    return true;
});

        Player player = event.getPlayer();
        getServer().broadcastMessage(player.getName() + " joined!");
    });
    
    registerEventListener(BlockBreakEvent.class, event -> {
        if (event.getBlock().getType().equals("diamond_ore")) {
            event.getPlayer().sendMessage("You found diamonds!");
        }
    });

// Get a component from an entity
HealthComponent health = entity.getComponent(HealthComponent.class);
if (health != null) {
    health.setHealth(health.getHealth() + 10);
}

// Check if entity has component
if (entity.hasComponent(FlyingComponent.class)) {
    // Handle flying entity
}
