Server requirements
- PaperMC 1.20 or newer (up to the latest 1.21.x). RefineryCore compiles against the plain
paper-api, notpaperweight.userdev, since it only uses public Bukkit/Paper API — this means one build of RefineryCore loads on any Paper build in that range without needing a version-pinned jar. - Java 21 toolchain.
Adding the dependency
RefineryCore is published to Refinery’s Reposilite instance. Add the repository and dependency to your plugin’sbuild.gradle.kts:
VERSION with the latest published version.
Declaring the dependency in plugin.yml / paper-plugin.yml
Your plugin needs to load after RefineryCore, so declare it as a hard dependency:bukkitPluginYaml in Gradle:
Implementing RefineryPluginImplementation
Your plugin’s main class should implement RefineryPluginImplementation to get access to the command registry, console logging, and server-version helpers:
MyPlugin.java
