CodeLib

A Paper plugin that downloads and extracts common Java libraries for Coder addons.

---

What it does

• Downloads a curated set of libraries on startup
• Extracts each .jar into /plugins/CodeLib/extractedLibs/<name>/
• Self-disables once done — no persistent footprint
• Supports custom extra dependencies via extraDeps.yml
