Dear Guix hackers,

when installing plantuml in a pure environment, it throws an java.awt.AWTError: Can't connect to X11 window server using ':1' as the value of the DISPLAY variable.

To reproduce:

$ guix environment --ad-hoc --pure plantuml -- plantumlNo protocol specified
Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using ':1' as the value of the DISPLAY variable.
	at sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)
	at sun.awt.X11GraphicsEnvironment.access$200(X11GraphicsEnvironment.java:65)
	at sun.awt.X11GraphicsEnvironment$1.run(X11GraphicsEnvironment.java:115)
	at java.security.AccessController.doPrivileged(Native Method)
	at sun.awt.X11GraphicsEnvironment.<clinit>(X11GraphicsEnvironment.java:74)
	at java.lang.Class.forName0(Native Method)
	at java.lang.Class.forName(Class.java:264)
	at java.awt.GraphicsEnvironment.createGE(GraphicsEnvironment.java:103)
	at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:82)
	at java.awt.image.BufferedImage.createGraphics(BufferedImage.java:1181)
	at net.sourceforge.plantuml.FileFormat.<clinit>(FileFormat.java:93)
	at net.sourceforge.plantuml.Option.<init>(Option.java:97)
	at net.sourceforge.plantuml.Run.main(Run.java:93)

When I leave out --pure, it works, so I assume that a dependency on X11
might be missing.

Best wishes,
Arne

Is the environment variable XAUTHORITY set?
Compare the value inside the environment and outside the environment.

Perhaps "XAUTHORITY" should be added to %precious-variables in
guix/scripts/environment.scm.  An untested patch is attached,
I'll test it now.

Greetings,
Maxime.

I have the following scriptlet that someone shared for running eolie in
a container. I'm guessing it could be modified to run platuml if needed.
