Re: After installing Java, what should I set JAVA_HOME to?

I don't want to use Guix to build my project because I'm developing it. So, for example, I want to run tests often, and that uses Gradle. I want to integrate a build into my editor. I want to make a Guix manifest that can set up a machine for other people to use, and they don't want to use Guix for day-to-day development.

I am not sure what trust store is being used. I'm also not sure how to check what trust store is being used.

So when using Guix, what should $JAVA_HOME be set to? Has anyone else done a Java setup using Guix?

Perhaps Java cannot find/access the truststore (or can access it but
found nothing in it)?  Do you know what trust store is being used?
Where is it, and what are its permissions?

I think a bigger question here is why do you need to use Gradle directly
to build your project?  What's stopping you from using Guix to do it?
