ViaUpdater
A Paper plugin that keeps your ViaVersion plugins up to date automatically.
It supports pulling builds from Jenkins CI servers and from GitHub Actions artifacts or source code.
Projects are fully configurable through a YAML config file.

Features

• Update ViaVersion, ViaBackwards, ViaRewind, and any other configurable project
• Two source types: Jenkins CI and GitHub (source build or workflow artifact)
• Per-project source selection with a named default
• Blocking startup update before ViaVersion loads
• Auto-update scheduler with a configurable interval
• Cancellable updates via /viaupdater cancel
• In-game command with tab completion
• Isolated Gradle and Maven cache inside the tmp folder during source builds (configurable)

Installation

1. Build the project with ./gradlew build
2. Drop the jar into your server's plugins folder
3. Start the server once to generate plugins/ViaUpdater/config.yml
4. Fill in your GitHub token and adjust the project list as needed
5. Restart or reload the config with /viaupdater reload

Configuration
