SNAPSHOT versions looks in the wrong place

[terlar]

I stumbled upon https://clojars.org/kitchen-async/versions/0.1.0-SNAPSHOT

Which will generate:

  {
    name = "kitchen-async";
    path = pkgs.fetchMavenArtifact {
      inherit repos;
      artifactId = "kitchen-async";
      groupId = "kitchen-async";
      sha512 = "0d6f8ce7b94b538e00e4a6719362dfe121b0db303906f46b638943c087ac1861442ea4896211110a06a01ecd5fab44dc7deb3b26d918c263be18751ff783492c";
      version = "0.1.0-SNAPSHOT";
    };
  }

This will look for:
https://repo.clojars.org/kitchen-async/kitchen-async/0.1.0-SNAPSHOT/kitchen-async-0.1.0-SNAPSHOT.jar

However, the resulting artifact won't exist:
https://repo.clojars.org/kitchen-async/kitchen-async/0.1.0-SNAPSHOT/

Seems if you provide the url attribute to the artifact it will work.

Thanks for this report, I've been looking into it. The SNAPSHOT is a wildcard which maven modifies to the latest timestamp of the given SNAPSHOT release. I'll see if I can find some lower lever tooling to tap into the resolver. But speaking with some of the tools.deps devs (Alex Miller), it seems this functionality isn't handled there at all.

I see, that sounds very tricky to solve then. If it is possible to gather this information, I am quite sure it will require some further modifications to fetchMavenArtifact.

And you would pass something like:

{
  artifactId = "kitchen-async";
  groupId = "kitchen-async";
  sha512 = "0d6f8ce7b94b538e00e4a6719362dfe121b0db303906f46b638943c087ac1861442ea4896211110a06a01ecd5fab44dc7deb3b26d918c263be18751ff783492c";
  version = "0.1.0-SNAPSHOT";
  snapshot = "20191108.004735-9";
}

Which would look for a URL like:

https://repo.clojars.org/kitchen-async/kitchen-async/0.1.0-SNAPSHOT/kitchen-async-0.1.0-20191108.004735-9.jar

I guess the logic would be if snapshot is provided, replace SNAPSHOT in the artifact name with the value of attribute snapshot.

that's an idea, not bad.

Hello, is there any news on this issue? I am trying to package Logseq, but I encountered the following error:

error: cannot download crisptrutski_boot-cljs-test-0.2.2-20160402.204547-3.jar from any mirror

Additionally, the previous workaround no longer works:

error: function 'anonymous lambda' called with unexpected argument 'snapshot'

Any help or updates would be appreciated. Thank you!

This is not implemented yet, I don't have access to the code anymore, but I remember extending fetchMavenArtifact to support the snapshot keyword as I described.

Support for this would have to be added to nixpkgs first.
