I want to build a package with the binary of one of my tests (using the go testing framework). I'm using buildGoModule for everything else so I'd like to use that too. I thought this would be easy but the best I could figure out was to use buildGoModule and then just override buildPhase = "go test -c -o mytest ./mytest"; (and then installPhase to copy it into $out). That works but I'm missing things like tags and other build flags. I can add those back but it's starting to feel a little wrong.. is there a better way to do this?

looked it up, we copy buildPhase and make the following two changes:

Hey y'all I'm trying to use the externalPlugins with coredns. I can't seem to add coredns-tailscale or coredns-blocklist.

This is the error I'm seeing https://gist.github.com/anthr76/5d5f43ecc2791c1d1859a6d0dcaf0b67

This is what my code looks like:

could you try overrideAttrs-ing that with modBuildPhase = (old.modBuildPhase) + "go mod tidy && go mod vendor"?

I ended up seeing the same error :(

Which doesn't make much sense because I see the plugins are down before hand

I've opened a bug report here https://github.com/NixOS/nixpkgs/issues/307750

I also tried taking a overlay approach in a more manual manner to understand what's breaking where but it seems like my modBuildPhase isn't detected

  modifications = final: prev: {
    coredns-snowflake = prev.coredns.overrideAttrs (oldAttrs: {
        vendorHash = "";
        modBuildPhase = (oldAttrs.modBuildPhase) + ''
