Gradle2nix V2: Call for testers

OK, I’ve got something I’d like to contribute, I’m just wondering how to go about it now…

It would be extremely useful if there were a mode I could put normal gradle2nix builds in where I could set __sandbox = false; and the plugin would run through the tasks I specify in the derivation as if I were running the gradle2nix command. Full internet connectivity and so on, but the lockfile can also be a build artifact.

I’m hoping to run something like that in CI. If one of our developers makes a change that touches dependencies and sets the correct option on their test build, it will generate the lockfile for them, automating a bunch of toil.

Any initial thoughts @tad?
