:classifier in exclusions forbidden by Clojars

[blueberry]

This is related to #515, which should have been solved, but is a colateral issue.

I need to exclude a dependency that contains macOS binaries from my library that I deploy to Clojars since it (unecessary) breaks the library on macOS.

I do that by adding

:exclusions [[org.jcuda/jcuda-natives :classifier "apple-x86_64"]]

to the dependency in project.clj

It works as expected.

However, Clojars refuses to deploy it, with the following message:

Could not transfer metadata uncomplicate:neanderthal/maven-metadata.xml from/to clojars (https://clojars.org/repo/): Access denied to: https://clojars.org/repo/uncomplicate/neanderthal/maven-metadata.xml, ReasonPhrase: Forbidden - invalid pom file: Unrecognised tag: 'classifier' (position: START_TAG seen ...</groupId>\n          <classifier>... @125:23).
Failed to deploy metadata: Could not transfer metadata uncomplicate:neanderthal/maven-metadata.xml from/to clojars (https://clojars.org/repo/): Access denied to: https://clojars.org/repo/uncomplicate/neanderthal/maven-metadata.xml, ReasonPhrase: Forbidden - invalid pom file: Unrecognised tag: 'classifier' (position: START_TAG seen ...</groupId>\n          <classifier>... @125:23).

Just to confirm, the exclusions that you've set do work to exclude the macOS library if you use it from a locally installed version? I'm pretty sure that's what you're saying, just wanted to check.

[blueberry]

Yes, they do. On both linux and macOS. The step that is refusing them is lein deploy clojars.

[tobias]

We're using org.apache.maven.model.io.xpp3.MavenXpp3Reader (from [org.apache.maven/maven-model "3.0.4"]) to read the pom file, and that is what is throwing that error. We may need to upgrade our dependency - it looks like the version we are using doesn't accept the pom that lein is generating.

Can you share the pom.xml that lein creates?

This is one of the variations that I tried. The only difference is where the exclusions are and how many there are, but every variation gets blocked by Clojars.

[tobias]

From looking at the maven xsd, classifiers aren't legal within exclusion blocks, even in the latest version of the xsd. So that would imply that lein is generating invalid poms. But I wonder what the maven solution is for excluding based on classifier?

[blueberry]

I found that solution in https://github.com/technomancy/leiningen/blob/master/sample.project.clj

I didn't realize it's illegal in maven. Bummer. I hoped it is just a configuration in Clojars for some marginal reason. It would have nicely solved the macos issue in my project...

Thank you for clarifying this!
