Description

Hi.
I've tried to follow the documentation at https://maven.apache.org/guides/mini/guide-resolver-transport.html to migrate from Wagon to the new HTTP Artifact Resolver, but it's not clear to me where and how I should set the new aether.connector.http.preemptiveAuth property in order to make the resolver use it properly, like it was with Wagon.

My (template of the) settings.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          </mirror>
      </mirrors>
    </settings>

but the property seems to be ignored, causing Maven to complain that's not able to find my artifacts.
As (hopefully temporary) solution, I'm setting the MAVEN_ARGS environment variable with the value -Daether.connector.http.preemptiveAuth=true.

The weird thing is that, in DEBUG, I can see that somehow the property is applied and the credentials are picked up

[DEBUG] Using transporter HttpTransporter with priority 5.0 for https://<artifactory-host>/artifactory/<repository>/
[DEBUG] Using connector BasicRepositoryConnector with priority 0.0 for https://<artifactory-host>/artifactory/<repository>/ with username=<username>, password=*** 

but, somehow, only once while when applying -Daether.connector.http.preemptiveAuth=true I can see the same logs multiple times (maybe once for every artifact).

Can you please provide some guidance/help on this?
I would also suggest to add to the documentation a/some example/s on how the migration should be really done.
