Allow java arguments to read environment variables

[m1dugh]

Role

I package multimc for nixos

Suggestion

I want the java arguments to resolve environment features

Benefit

It would allow to specify a specific folder for the native libraries allowing usage of both nixos and wayland

This suggestion is unique

• I have searched the issue tracker and did not find an issue describing my suggestion, especially not one that has been rejected.

You may use the editor below to elaborate further.

Since nixos does libraries differently, and minecraft needs patched library for wayland, the only way to run minecraft on wayland nixos, is to specify manually the path of the derivation as java.library.path and org.lwjgl.glfw.libname everytime the package is updated.
A simple way to fix this would be to be able to use environment variables in java arguments for each instance, or for java to be able to read environment variables (such as JAVA_TOOL_OPTIONS) when launched from multimc.
