Support maven mirror with authentication

Wed, 07 Apr 2021 22:48:13 +0000

The Clojure tools.deps resolves remote Maven repositories, and generally obeys the Maven settings.xml. Unfortunately, in the following settings example, it will not pickup the authentication for the mirror. According to Maven convention, the mirror's Id should be used to determine the server settings, in this case "planetmirror.com"

<settings>
    <servers>
        <server>
            <id>planetmirror.com</id>
            <username>my_login</username>
            <password>my_password</password>
            <configuration></configuration>
        </server>
    </servers>
    <mirrors>
        <mirror>
            <id>planetmirror.com</id>
            <name>PlanetMirror Australia</name>
            <url>http://downloads.planetmirror.com/pub/maven2</url>
            <mirrorOf>central</mirrorOf>
        </mirror>
    </mirrors>
</settings>

The reason is that the code in tools.alpha.util.maven.clj uses the repository name to find the server-settings:

The following patch fixes the issue:
