Jetpack is a Minecraft plugin that lets you write and run scripts on your Paper server. Build features in a small scripting language without recompilation or restarts.
Features
- Write server logic in
.jetfiles and load them live, with no Java build or restart - Register commands, react to server events, and run timed intervals
- Reach the full Paper/Bukkit API through a native bridge
- Statically typed, so errors are caught before a script runs
Requirements
- Paper 1.21.10 or newer
- Java 21 or newer
Simple Example
listener PlayerJoinEvent onJoin(object event) {
object player = event.player
player.sendMessage($"Hello, {player.name}!")
}
Ecosystem
- Documentation: setup, syntax, scripts, and module reference
- Language Server: VS Code extension with highlighting, diagnostics, and completion for
.jetfiles - Skill: agent skill for writing, reviewing, and debugging
.jetscripts
