Generate nix for Jenkins plugins.

jenkinsPlugins2nix

Usage: jenkinsPlugins2nix [-r|--dependency-resolution [as-given|latest]]
                          (-p|--plugin PLUGIN_NAME{:PLUGIN_VERSION})
  Generate nix expressions for requested Jenkins plugins.

Available options:
  -r,--dependency-resolution [as-given|latest]
                           Dependency resolution (default: latest)
  -p,--plugin PLUGIN_NAME{:PLUGIN_VERSION}
                           Plugins we should generate nix for. Latest version is
                           used if not specified.
  -h,--help                Show this help text

Along with recent nixpkgs, you can then do the following.

jenkinsPlugins2nix -p github-api > plugins.nix

and in your configuration.nix:

services.jenkins.plugins = import plugins.nix { inherit (pkgs) fetchurl stdenv; };

Version specification

Care is taken to preserve versions of plugins explicitly specified by the user, even with the as-given resolution strategy. For example, if plugin A has a dependency B:0.2 in its manifest file and we specify:

jenkinsPlugins2nix -r latest -p A:0.7 -p B:0.1

We will end up with A:0.7 and B:0.1. This also applies when no explicit version is provided which is equivalent to asking for the latest one.

In case we only ask for A, the version of B will depend on --resolution-strategy.
