Individual Keep-Inventory (for Bukkit and Sponge)

This is a simple plugin I have made, which allows you to set the keepInventory mechanic in Minecraft in a per-player way.

Server Requirements:

Java 8;
If you use a Bukkit-based server (Craftbukkit/Spigot/Paper/etc...): This was tested in version 1.12.2 of Minecraft; in theory, this should work as far back as 1.8.8 though (and newer versions too).
If you use a Sponge-based server (SpongeVanilla/SpongeForge/etc...?): This was tested in version 1.12.2 of Minecraft and version 7.3.0 of SpongeVanilla; in theory, as long as your server version supports that API version you should be fine.

How to use it?

WARNING: Do NOT set the keepInventory gamerule to true in the world, through /gamerule or any equivalent command (if you have a world management plugin); this plugin won't work otherwise. If you have already done it, set it to false.

1 - Install this plugin and a permission management plugin in your server (LuckPerms is what we recommend!);

2 - With the permission management plugin you have installed, give the permission iki.events.playerdeath.keepinventory to whoever you want.

Examples

Assuming you are using Luckperms:
1 - If you want to give keepInventory to a specific player or group:

/luckperms user <playername> permission set iki.events.playerdeath.keepinventory true

2 - If you want to give keepInventory to everyone except a specific player:

/luckperms group default permission set iki.events.playerdeath.keepinventory true

/luckperms user <playername> permission set iki.events.playerdeath.keepinventory false

And there might be other use-cases I could spend 40 more hours covering here.

How to Compile

Requirements:

JDK 8 or higher;
Maven 3.6.3 or higher.
