NilLoaderSDK

NilLoaderSDK is a Java 8 utility SDK for NilLoader-based Minecraft mods (legacy versions).

It provides:

• metadata helpers for NilLoader + KDL
• runtime bootstrap for KDL-only mods
• reflection/remapping helpers
• event bus and lifecycle events
• NIO networking utilities

Why NilLoaderSDK?

NilLoaderSDK is not only metadata tooling. It is a practical utility layer for legacy NilLoader mod development, with reusable APIs that reduce boilerplate and speed up feature development.

Use it when you want a single toolkit for lifecycle dispatching, reflection/remapping, networking, event handling, and modernized metadata support.

Key Features

• Lifecycle + Entrypoint system
  • premain / hijack dispatching via ServiceLoader, JVM properties, and properties file
  • Default SDK modules for centralized startup flow
• Event bus for mod architecture
  • Lightweight event system with cancellable events and priority ordering
  • Lifecycle events for pre/post entrypoint dispatch hooks
• Networking stack (Java NIO)
  • Client/server implementations with packet registry and codec
  • Optional auto-network bridge for fast integration
• Reflection + remapping helpers
  • Utilities for interacting with obfuscated legacy internals safely and repeatedly
• Metadata bridge (CSS + KDL)
  • Supports .nilmod.css and .nilsdkmod.kdl
  • KDL-only runtime bootstrap for SDK-aware mods when root CSS is absent
  • Dependency policy support (requires, safeload, load order hints)
• Diagnostics for pack/mod developers
  • Verbose bootstrap pipeline logs
  • Loaded-mod table output:
    • ID | Name | Version | Authors | License
