pigio not initialized issue

[Ghozti]

So this was working a few days ago and I did not change any code that could have broken it. I basically followed the minimal example and translated it to toggle an led. However now I am getting this issue

root@raspberrypi:/home/pi# java -jar /home/pi/Downloads/desktop-1.0.jar error: XDG_RUNTIME_DIR not set in the environment.

I also integrated pi4j with libgdx but I don't see how that is breaking this.

Hello, did you try running as sudo ?
What is new in this log for me is this XDG_RUNTIME_DIR. You know what that's meant for?

i ran it using
$sudo su PATH_TO_JAR
the led does blink for like a fraction of a second then the program crashes and gives me this error. And as for the XDG_RUNTIME_DIR, I do not know what it is or why I am getting that error.
