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 usePreemptive 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. was (Author: kwin): My previous observation is not correct.
