That's because what Mohamed is referring is the old (3.x) HttpClient
and not the new (4.x) one which have different (sometime very
different) API.
The main issue you have is probably the fact that XWiki does not ask
the client for credential by default since anonymous access is valid.
That means you need to force preemptive authentication which is very
easy in 3.x (just a call to setAuthenticationPreemptive like in
Mohamed's example) and quite harder in 4.x (they find dangerous to
support it like they used to...).
You can find various examples on Google and the official documentation
is on https://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication…
(section "4.6. Preemptive authentication").
