# \ud83d\ude80 AutoServerUpdaterX<\/p>\n
**Keep your server running on the latest security and performance patches without lifting a finger.**<\/p>\n
This project is a **fork** of the original AutoServerUpdater, specifically updated to maintain compatibility with modern server infrastructures and the latest API standards.<\/p>\n
I recommend using AutoUpdatePlugins if you want your plugins to be updated automatically as well!<\/p>\n
### \ud83d\udd04 Why this fork?
\nThe original plugin broke after **PaperMC migrated their download service from Bibliothek (v2) to Fill (v3)** and deprecated legacy endpoints. This fork resolves those connection issues and introduces more robust build-tracking logic.<\/p>\n
### \u2728 Key Features
\n* **API v3 Support:** Fully compatible with the new PaperMC Fill download service.
\n* **Intelligent Build Tracking:** Scans all available API metadata to identify the highest build ID, ensuring accuracy even for Alpha and Experimental releases.
\n* **Configurable Update Actions:** Choose between a Spigot-native `RESTART` or a clean `STOP` (perfect for Docker or Pterodactyl users).
\n* **User-Agent Compliance:** Implements mandatory identity headers to comply with PaperMC’s latest infrastructure requirements.<\/p>\n
### \ud83d\udce6 Supported Software
\n* Paper
\n* Purpur
\n* Leaf<\/p>\n
### \ud83d\udee0 Configuration
\nThe plugin creates a `config.yml` on the first run. You can customize the behavior after a download:
\n“`yaml
\n# Options:
\n# RESTART – Uses Spigot’s restart command (default).
\n# STOP – Safely shuts down the server. Recommended for loop scripts.
\nupdate-action: RESTART
\n“`<\/p>\n
### \u26a0\ufe0f Disclaimer
\n> [!DANGER]
\n> Using auto-updaters in production environments is at your own risk. This plugin overwrites your active server JAR. Always ensure you have regular backups configured before enabling automated updates.<\/p>\n
**Important regarding `while true` loops:**
\nIf you are using a startup loop (e.g., `while true; do java…; done`), it is **highly recommended** to set `update-action` to `STOP`. <\/p>\n
Using `RESTART` in combination with a shell loop often triggers a new server instance before the old one has fully terminated. This can lead to:
\n* **`Failed to bind to port`** errors (Port already in use).
\n* **`session.lock`** errors (World already in use).
\n* **Zombie processes** (Multiple instances running simultaneously).<\/p>\n
—<\/p>\n
**Note:** If no restart script or loop is configured on your host, the server will shut down to apply the update but will not automatically start back up.<\/p>\n
### \u2696\ufe0f License & Fork Information
\n* **Divergence:** This version contains a complete rewrite of the API fetching logic (switching to Fill v3), adds JSON parsing via Jackson, and implements mandatory User-Agent headers and configurable shutdown logic.
\n* **Original License:** The original project is licensed under the **MIT License**.<\/p>\n","protected":false},"excerpt":{"rendered":"
