I see.  I know that some people have been using Guix for local
development [1] [2], so I thought that maybe you could use Guix for
local development in this case, too.  If it isn't possible, then I
wonder what we would need to change or add to make it possible?

I haven't tried local Java development with Guix, so I don't know much
about how it ought to be done.  There don't seem to be many Java
packages in Guix yet, so I suspect a lot of machinery that we need might
not be there.

I tried installing java-junit in a temporary profile with 'guix package
-p test-profile -i java-junit', and 'guix package -p test-profile
--search-paths' doesn't recommend any search paths...  It seems that it
just installed a JAR file, so the way you'd set up the CLASSPATH for
local development seems unclear to me.  In your case, I don't really
know what you'd want to set JAVA_HOME to, either, if anything.

Anyway, in the meantime, I hope you can figure out how to get Gradle
working with the Guix-installed Java.  If you do, please let me know;
I'm interested in learning more about how one would do Java development
with Guix.
