Autoupdaterestart

AutoUpdateRestart

AutoUpdateRestart is a plugin that automatically updates your plugins. It also restarts your server for you (by restart, I mean turn it off and back on). It works on Bukkit, Paper, and Spigot on 1.21.x - 26.2

What it does

At startup, it reads the running server's Minecraft version and loader name, then checks installed plugins against Modrinth and Hangar. This is strictly a one-time check, not a repeating poll: its delayed startup trigger is cancelled after use, and the temporary background worker is shut down immediately afterward. When no update is found, the checker clears its results, logs that it is idle, and uses no background task or worker. Players with autoupdater.alert receive an alert in chat when they join.

When automatic updates are enabled, compatible JARs are downloaded into plugins/update/. This is Bukkit's safe update staging directory: the server replaces the original JAR on its next startup. A loaded plugin JAR is never deleted or replaced while it is executing, which prevents corrupting the running server. With automatic updates disabled, use /updater update after /updater check to stage the discovered updates.

The restart scheduler is the only long-lived task, and exists only when restart.enabled is true. It warns each minute during the configured warning window and calls the normal Bukkit shutdown at the end. Your host/start script must be configured to start the server again after shutdown.
