JCPlugin Mod (1.20.1) – Library for Jomcraft Network

Behind every well-functioning modpack lies a quiet workhorse that keeps everything running smoothly. JCPlugin Mod serves as the core plugin loader for the DefaultSettings Mod, developed by the Jomcraft Network team. It hooks directly into the FML (Forge Mod Loader) startup sequence, ensuring that DefaultSettings integrates properly during the critical early loading phase — a task that sounds simple but is essential for modpack creators who rely on preconfigured settings shipping correctly to players.

Key Features

  • Core Plugin Loading for DefaultSettings — Acts as a bridge between the DefaultSettings Mod and the FML startup sequence, enabling proper initialization before other mods finish loading.
  • Multi-Loader Support — Works across Forge, Fabric, NeoForge, and Quilt, giving modpack developers flexibility regardless of their preferred ecosystem.
  • Wide Version Coverage — Supports Minecraft versions from 1.7.10 all the way to 1.21.11, covering both legacy and modern releases.
  • Background Library — Operates silently in the background as a dependency; no configuration or user interaction is needed once installed.

FAQ

Do I need JCPlugin if I don't use the DefaultSettings Mod?

No. JCPlugin exists specifically as a core loader for DefaultSettings. If you're not using DefaultSettings in your modpack or installation, there's no reason to install JCPlugin.

Will JCPlugin work on both client and server?

JCPlugin integrates with the FML startup sequence, which runs on both client and server environments. Install it wherever you have the DefaultSettings Mod loaded.

Is JCPlugin compatible with other library mods in the same modpack?

Yes. JCPlugin appears to be lightweight and focused solely on bootstrapping DefaultSettings during startup. It should not conflict with other library mods or APIs in your mod folder.
