About ModSync: Bootstrap

ModSync Bootstrap

Early Development Stage - This plugin is in very early development. Use at your own risk. Development is ongoing - please be kind with feedback and bug reports!

Summary: Required dependency for ModSync. Handles file deletions before mods are loaded to work around Windows file locking.

A bootstrap/early plugin for Hytale that handles file deletions before the server loads mods. This is a required dependency for the ModSync plugin.

Why Is This Needed?

On Windows, JAR files are locked while the server is running. This means mods cannot be deleted or replaced while they are loaded. The bootstrap plugin runs before mods are loaded and handles any pending file deletions queued by ModSync.

Installation

Download the modsync-bootstrap.jar file

Place it in your server's earlyplugins folder (create if it doesn't exist)

Start the server with the --early-plugins and --accept-early-plugins flags

How It Works

ModSync queues files for deletion in mods/Onyxmoon_ModSync/pending_deletions.json

On server startup, the bootstrap plugin runs before any mods are loaded

It reads the pending deletions file and deletes the queued files

The pending deletions file is cleared after processing

The server continues to load mods normally

Requirements

Hytale Server (release patchline)

Server must be started with --early-plugins and --accept-early-plugins flags

Server Start Flags

Add these flags when starting your Hytale server:

--early-plugins --accept-early-plugins

Important Notes

Library Only: This plugin does nothing on its own. It is a required dependency for ModSync.

No Configuration: There are no settings to configure. The plugin automatically processes pending deletions.

Safe Operation: If no pending deletions exist, the plugin does nothing.

Windows Compatibility: Primarily needed for Windows servers where file locking is an issue.
