From what I understand, this patcg helps build openjfx with gradle on guix, if you use the guix source in an environment, but reading the other patches, it doesn't look like gradle is actually used anywhere.

It looks like this patch is helpful in the sense that it allows users to manually build the package outside of guix, but is not used at all during the build of openjfx by guix itself.

Alexey, can you confirm?
