📖About LiveJava

LiveJava: The Native Java IDE for your Server

Say goodbye to restarts, reloading times, and limited scripting languages. Meet LiveJava—the ultimate bridge between professional development and server management.

LiveJava embeds a secure, VS Code-powered Web IDE directly into your Minecraft server. It allows you to write, compile, and execute Native Java code in real-time. No more reload commands, no more heavy third-party scripting engines—just pure, high-performance Java.

🔥 Key Features

  • Zero-Restart Workflow: Modify your code, hit "Build", and see the changes active instantly.
  • Native Performance: Unlike Skript or other parsers, your code runs directly on the JVM, delivering maximum server performance.
  • Embedded Web IDE: A clean, VS Code (Monaco) based environment with auto-completion, syntax highlighting, and error tracking—right in your browser.
  • Auto-Classpath Injection: LiveJava automatically detects all installed plugins on your server. Need Vault or WorldEdit? Just import them and start using their APIs immediately!
  • Multi-Class Project Support: Stop cramming code into a single file. Build structured, professional projects with multiple classes.
  • High Security: Your IDE is accessible via a custom port, locked with a unique IP filter, and protected by a secret key. Only you have the power.
  • Persistent Storage: All your code is saved directly to your disk. No data loss on server restarts.

🚀 Why choose LiveJava over Skript?

🛡️ Security First

We know "remote code execution" sounds scary. That's why LiveJava is built with a "Loopback-Only" policy. The editor is isolated and accessible only via the specific IP and secure key combination you define in the configuration.

📥 Getting Started

  1. Install the plugin.
  2. Set your custom port and secret key in config.yml.
  3. Open your browser to http://your-server-ip:port/your-secret-key.
  4. Start coding and save to deploy!

LiveJava is 100% Free and Open Source. If you love the project, consider leaving a star on GitHub!
