PluginUpdateChecker

This is a library for Minecraft Bukkit / Spigot / Paper server plugins. It is designed to provide easy update checking functionality to any plugin.

This is not a standalone plugin (no plugin.yml): you embed the JAR in your plugin, typically with Maven Shade and package relocation, so multiple plugins can each ship their own copy without classpath conflicts.

The checker runs network work asynchronously, then applies results, events, and optional console/player messages on the main thread. Built-in sources include GitHub Releases (owner/repo), a plain-text URL, or your own supplier. Version comparison uses Maven-style ordering (not naive string compare).

Language / build	Java 17+, Maven
Coordinates	com.failprooftech:plugin-update-checker:1.0.0 (see pom.xml)
