Example Source code to replicate the issue (Optional)
It would help us immensely if we were to have an example test source code or a snippet where you can see this problem, you could attach a zip file along with this

MavenPomDownloader tried to reattempt download if there is a 404 and this time it does that without authentication. We probably can solve this by not attempting download if it is a 404 or attempt without credential only for a 401
