KappaEssentials Extension Loader
A lightweight and secure extension system for KappaEssentials
Supports Paper 1.21+ · Java 21
What is it?
KappaEssentials Extension Loader allows you to safely load modular .jar extensions for the KappaEssentials plugin.
It's a separate plugin that reads .jar files from a specific folder and loads them only if they are explicitly allowed by their internal ID.
How it works
On startup, the loader looks inside: plugins/KappaEssentials/extensions/
Each .jar must contain an extension.yml file with:
id: my-extension main: my.package.MyExtensionClass
The loader only enables .jar files with IDs that are hardcoded in its whitelist.
It loads the main class, initializes it, and calls onEnable() and onDisable() on shutdown.
Features
Modular, keep KappaEssentials clean and minimal
Simple API, just implement KappaExtension
Supports Paper 1.21+, built for modern servers

For Extension Developers
Extensions must:
Be valid .jar files
Contain an extension.yml at root:
id: example-extension
main: net.example.MyExampleExtension
More dev tools, examples, and extension templates will follow.
