Is there any Nix-aware CI besides Hydra and Hercules?
Or maybe plugins for Jenkins or GitLab?
By Nix-awareness I mainly mean making a graph of native tasks from
nix-instantiate and distribute them to CI workers, and showing those graphs as a single CI-tasks to avoid pollution of the root namespace. Plus import of Nix build logs into CI system.
Why not Hydra/Hercules: to integrate with things unrelated to Nix (uploading to Maven, etc). It seems easier to add Nix support to Jenkins than to enrich Hydra with all it lacks.
