# UltraPluginManager (UPM)<\/p>\n
**UltraPluginManager (UPM)** is a modern, safe, and advanced plugin management system for Spigot servers (1.18.2+). It serves as a robust alternative to PlugMan, featuring a clean architecture, asynchronous operations, and a user-friendly GUI.<\/p>\n
  <\/p>\n
## \u2728 Features<\/p>\n
* **Plugin Management:** Enable, Disable, Restart, Load, and Unload plugins dynamically.
\n* **Modern GUI:** A chest-based GUI to manage plugins visually with pagination and status indicators.
\n* **Safety First:**
\n * Prevents disabling critical plugins (e.g., Vault, ProtocolLib, WorldGuard).
\n * Checks for dependencies before disabling.
\n * Detects circular dependencies.
\n* **Async Operations:** Heavy operations (like loading\/unloading) are handled asynchronously to prevent server lag.
\n* **Multi-Language Support:** Built-in support for English (`en`) and Hungarian (`hu`), with the ability to add custom language files.
\n* **Tab Completion:** Full tab completion for all commands and file names.
\n* **Hex Color Support:** Beautiful chat and GUI formatting with Hex color codes.<\/p>\n
## \ud83d\udce5 Installation<\/p>\n
1. Ensure your server is running **Java 17** or newer.
\n2. Download the `UPM.jar`.
\n3. Place the jar file into your server’s `plugins` folder.
\n4. Restart the server.<\/p>\n
## \ud83d\udee0 Commands & Permissions<\/p>\n
| Command | Alias | Description | Permission | **Wildcard Permission:** `upm.admin` grants access to all commands.<\/p>\n ## \u2699\ufe0f Configuration<\/p>\n The `config.yml` allows you to customize the plugin’s behavior.<\/p>\n “`yaml # Toggle debug messages in console # GUI Title # Plugins that cannot be disabled\/unloaded via UPM ### Language Support ## \u26a0\ufe0f Warning Regarding `unload` and `reload`<\/p>\n While UPM uses advanced techniques to unload plugins (closing ClassLoaders, clearing references), Java’s architecture makes “clean” unloading difficult without a full server restart.<\/p>\n * **Use `\/upm reload` for development:** It is great for testing small changes in your own plugins. ## \ud83d\udc68\u200d\ud83d\udcbb Developer<\/p>\n Created by **Ywxlol**.

\nUPM generates `lang_en.yml` and `lang_hu.yml` by default. To create a new language:
\n1. Copy `lang_en.yml` and rename it (e.g., `lang_it.yml`).
\n2. Translate the messages.
\n3. Set `language: it` in `config.yml`.
\n4. Run `\/upm reload`.<\/p>\n
\n* **Avoid reloading complex plugins:** Plugins with heavy packet usage (ProtocolLib) or complex dependency injections may not reload cleanly.
\n* **Memory Leaks:** Repeatedly loading\/unloading plugins *can* lead to Metaspace memory leaks over time. **Always restart your server for production changes.**<\/p>\n
