Snapshot Follower

English | 中文

Keep your Minecraft server up-to-date with the latest snapshot

The plugin periodically queries about the latest Minecraft snapshot from mojang API. When a new snapshot is spotted, it will download the snapshot server.jar, stop the running server, replace the server.jar and finally start the server with the latest Minecraft snapshot

Note

When the plugin is loaded or the server starts, the plugin will try to detect the current Minecraft version of the server by reading the version.json inside the jar file, so it knows if the currently running Minecraft version matches the latest snapshot.

If the detection fails, the plugin will simply assume that the current Minecraft version is the latest snapshot

Optionally, an HTTP POST webhook can be triggered when the update finishes
