Geyser and Floodgate auto uploader

# GeyserUpdater An automatic updater plugin for GeyserMC / Floodgate. Supports Spigot (and forks like Paper), BungeeCord, and Velocity. Features - Fetches the latest stable versions of GeyserMC and Floodgate from the Jenkins/download API and overwrites the existing JARs in the plugins directory - Fetches the latest MCXboxBroadcast (from Modrinth) and places it in the Geyser extensions folder (optional) - Automatic update checks - On server startup - At a specified interval (e.g., every 12 hours) - When a player with a specific permission logs in (can be enabled/disabled) - Manual command: /geyserupdate (Permission: geyserupdater.admin) - Configurable language, messages, targets, intervals, and restart commands Build - Prerequisites: Java 17, Maven 3.8+ - Instructions: - Run `mvn package` in the directory where you cloned the repository - Artifacts: - `spigot/target/GeyserUpdater-Spigot-1.0.0.jar` - `bungee/target/GeyserUpdater-Bungee-1.0.0.jar` - `velocity/target/GeyserUpdater-Velocity-1.0.0.jar` Installation - Place the appropriate JAR for your server platform into the plugins folder - Start the server to generate the `config.yml` file (it will be identical to the default config included in this README) - The plugin automatically detects existing Geyser / Floodgate JARs by searching for files in the plugins directory that contain "geyser" or "floodgate" in their names - If no existing JARs are found, it will create new ones with standard names (e.g., `Geyser-Spigot.jar`, `floodgate-velocity.jar`) Commands & Permissions - `/geyserupdate` - Description: Immediately runs an update check - Permission: `geyserupdater.admin` Configuration File (`config.yml`) - `enabled`: Enables or disables the plugin - `language`: Language setting (`ja` / `en` / `de` / `ko`, default: `ja`) - `checkOnStartup`: Enables or disables the update check on startup - `periodic.enabled`: Enables or disables the periodic update check - `periodic.intervalHours`: The interval for periodic checks (in hours) - `adminLogin.enabled`: Enables or disables the update check when a privileged player logs in - `adminLogin.permission`: The permission that triggers the check on login (default: `geyserupdater.admin`) - `targets.geyser | targets.floodgate | targets.mcxboxbroadcast`: Choose which plugins to update - `postUpdate.notifyConsole`: Notifies the console after an update - `postUpdate.notifyPlayersWithPermission`: Sends an in-game chat notification to players with permission - `postUpdate.runRestartCommand`: Automatically executes a restart command after an update - `postUpdate.restartCommand`: The restart command to execute (e.g., `restart` or `end`) - `messages..*`: Customize messages (e.g., `messages.ja.*`) - For compatibility, `messages.*` is also read when `language=ja` How it Works - Download URLs: - Geyser: `https://download.geysermc.org/v2/projects/geyser/versions/latest/builds/latest/downloads/{platform}` - Floodgate: `https://download.geysermc.org/v2/projects/floodgate/versions/latest/builds/latest/downloads/{platform}` - MCXboxBroadcast: `https://api.modrinth.com/v2/project/mcxboxbroadcast/version` - `{platform}` is `spigot` | `bungeecord` | `velocity` - The latest JAR is downloaded to a temporary file and its SHA-256 hash is compared with the existing JAR - If the hashes are identical, it is considered "up to date," and the file is not replaced - If they differ, the existing file is overwritten using an atomic replacement operation - A server or proxy restart is required after an update is applied - To enable automatic restarts, set `postUpdate.runRestartCommand` to `true` and configure `restartCommand` to match your environment - MCXboxBroadcast is placed in the Geyser extensions folder - Example: `plugins/Geyser-Spigot/extensions` Notes / Known Limitations - If a download fails due to network issues or other errors, the existing plugin files will not be affected - The plugin cannot detect Geyser/Floodgate files if they have unusual names or are not located directly within the plugins folder (it only scans for *.jar files in the root of the plugins directory) - MCXboxBroadcast is always placed in `plugins/Geyser-Spigot/extensions` - The plugin does not display version numbers; it relies solely on hash comparison to determine if an update is available License - Apache License 2.0
