No Netherite Upgrade Template Duplication

Overview

NoTemplateDupe is a minimal Minecraft Paper plugin that prevents players from duplicating Netherite Upgrade Templates in crafting tables. Its sole purpose is to achieve more difficult Netherite progression without altering any other gameplay mechanics.

Features

• Blocks duplication of Netherite Upgrade Templates in crafting tables.
• Configurable plugin toggle — enable or disable the plugin via config.yml.
• Lightweight and efficient — no impact on other crafting mechanics or gameplay.

Installation

1. Place the no-template-dupe.jar file into your Paper server’s plugins folder.
2. Restart the server to activate the plugin.
3. Attempting a Duplication inside a Crafting Table will result in nothing, since the recipe itself is fully disabled.

Configuration

• config.yml is created automatically on first run.
• Options:

enabled: true   # Enable or disable the plugin

Commands

• None — the plugin works automatically.

Compatibility

• Tested on Paper 1.21.10.
• Works on multiplayer servers.
• Does not interfere with other plugins or vanilla crafting mechanics outside of Netherite Upgrade Template duplication.
