GeyserUpdater is the original plugin that downloads and applies new builds. It uses checksum validation to detect corrupted or modified (non-original) Geyser jar files for Spigot, BungeeCord, and Velocity, and can operate either manually or automatically.
Note: This is NOT an official GeyserMC plugin. It is made to work with Geyser, but it is not maintained or produced by GeyserMC. If you need support with this plugin, please do not ask the Geyser developers — instead, please go to our Discord server which is linked above.
Installation
Simply place the GeyserUpdater *.jar file in your server's plugins folder and restart your server.
Usage
| Commands | Permission |
|---|---|
/geyserupdate |
gupdater.geyserupdate |
After you run the /geyserupdate command or enable auto-updating, GeyserUpdater will check the currently-installed version of Geyser. If it's outdated, GeyserUpdater will automatically download the latest build of Geyser. Changes will only take place once the server has been shut down and restarted.
Please note that for BungeeCord and Velocity, if the server is not shut down cleanly, the new version of Geyser will not be applied.
