Building with a private dependency
Not sure if this is a bug, or perhaps it's just advice needed.
I have problem with building a project that contains a private dependency. It appears to be slightly different problem than described in https://github.com/tweag/gomod2nix/issues/3.
After gomod2nix asked me for credentials I just entered it and it did its job, but when I'm trying to build and that dependency came up this is what I got:
exporting https://gitlab.<snip>/<snip>/go-commons (rev 0b8910c77d4eac6c27ef7024e7596bfcfa07feff) into /nix/store/1348m1ip818a03dj49d4ljv5qm14rj7g-go-commons-0b8910c
Initialized empty Git repository in /nix/store/1348m1ip818a03dj49d4ljv5qm14rj7g-go-commons-0b8910c/.git/

Unable to checkout 0b8910c77d4eac6c27ef7024e7596bfcfa07feff from https://gitlab.<snip>/<snip>/go-commons.
Is there a way to let me compile to project? During build I don't even have an opportunity to enter credentials. Of course saved credentials as well like using insteadOf in git configuration don't work.
That concept isn't completely clear to me yet, but I'm wondering if: https://github.com/tweag/gomod2nix/blob/master/builder/default.nix#L50-L60 isn't violating IFD. If instead of using and parsing toml, gomod2nix would just generate a nix file that would be simply imported, wouldn't then nix respect local configuration?
I've added an override interface in https://github.com/tweag/gomod2nix/pull/42 for dealing with these types of issues. The same interface could also potentially be used to apply patches to individual upstream packages.
https://github.com/tweag/gomod2nix/pull/55 should help, but it's not a full fix for private dependencies which are generally a bit painful.
