-----------------------------------------------------------------
My previous observation is not correct. Indeed preemptive authentication could
work, as this is set here:
https://github.com/apache/maven-wagon/blob/wagon-2.4/wagon-providers/wagon-http-shared4/src/main/java/org/apache/maven/wagon/shared/http4/AbstractHttpClientWagon.java#L762,
but the default value for isPreemptive is still false
(https://github.com/apache/maven-wagon/blob/wagon-2.4/wagon-providers/wagon-http-shared4/src/main/java/org/apache/maven/wagon/shared/http4/HttpMethodConfiguration.java#L55)
and it is unclear how to overwrite that value for regular GET methods.

> Although by default the preemptive authentication should work now with Maven
> 3.0.4, a wireshare dump exposes, that each request for downloading a new
> dependency does not initially come with the authentication header. Only after
> Nexus replied with a 401 the right credentials are set in the authentication
> header. According to [1], since Maven 3.0.4 the default HTTP wagon uses
> preemptive authentication which cannot be disabled [2]. Even with Maven 3.1.1
> it does not work.
