KappaEssentials Extension Loader

KappaEssentials Extension Loader

A _secure_ and _secure_ extension system for _secure_ > 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

- Open design, more extensions coming soon!

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.
