ModelEngine fails on Arclight 1.21.1 because Server#getMinecraftVersion() no longer exists

[angelofwar25-png]

I have tried that...

• I am using the latest Arclight build

• I have read the FAQ and Troubleshooting, they didn't solve my issue

• I have searched existing Issues and found no duplicates

• The mods and/or plugins I use support my Minecraft version

• I have installed all required dependencies for the mods and/or plugins

• I have updated all mods and/or plugins to their latest versions

• This issue cannot be reproduced on a Spigot server
  (Mod-related issues are considered non-reproducible on Spigot)

• This issue cannot be reproduced on the Mod Loader server (Forge/NeoForge/Fabric)
  (Plugin-related issues are considered non-reproducible on mod loaders)

Issue Description

Hello! I’m currently trying to run ModelEngine R4.0.9 on an Arclight 1.21.1 hybrid server, and the plugin fails to load on startup. The error points to a missing Bukkit API method:

java.lang.NoSuchMethodError: 'java.lang.String org.bukkit.Server.getMinecraftVersion()'

This is the full stack trace excerpt:

java.lang.NoSuchMethodError: 'java.lang.String org.bukkit.Server.getMinecraftVersion()'
at com.ticxo.modelengine.api.ServerInfo.(ServerInfo.java:25)
at com.ticxo.modelengine.core.ModelEngine.configureNMSHandler(ModelEngine.java:312)
at com.ticxo.modelengine.core.ModelEngine.onEnable(ModelEngine.java:106)
...

It seems that newer Bukkit/Spigot-like hybrids (like Arclight 1.21.1) removed getMinecraftVersion(), and ModelEngine tries to call it during initialization, causing the plugin to fail before generating config folders.

⚠ Environment

Server type: Arclight 1.21.1 (NeoForge + Bukkit hybrid)

ModelEngine version: R4.0.9

MythicMobs version: Latest premium (not relevant because ModelEngine fails before hooking)

Java: 17

❓ Question

Is there a quick workaround or temporary patch available for hybrid servers that no longer use Server#getMinecraftVersion()?

Even a manual config option or experimental build would be extremely helpful for now, since many modded servers rely on Arclight.

Thank you very much for your hard work on this amazing plugin! 🙏

Steps to Reproduce

Install Arclight 1.21.1 (latest build).(NeoForge)

Copy ModelEngine R4.0.9 into the /plugins/ folder.

Start the server.

ModelEngine fails during startup before creating its data folders.

Server#getMinecraftVersion() is provided by Paper API, we are working on it now. See #47 for progress.
