FYI for users of AWS, the CodeArtifact service now supports Clojars as an "external connection" as of ~5 days ago. See also: https://docs.aws.amazon.com/codeartifact/latest/ug/external-connection.html and https://docs.aws.amazon.com/codeartifact/latest/ug/maven-deps.html. (I work for AWS on a different team, but contributed the change internally so that our Amazon Clojurians can use it)
Personal thanks to @alexmiller who https://clojure.atlassian.net/browse/TBUILD-26 a reproducible builds/tests issue that our folks wanted as part of introducing the feature 🙂
This is great, thanks!
