jycr commented on WAGON-453:
----------------------------
Sorry for my much too late response. I had a (very) long break.
Regarding property {{java.net.useSystemProxies=true}}, it's the same behavior
if I pass it with MAVEN_OPTS, or via command line.
I don't configure any proxy in {{settings.xml}}
Standard/default HTTP wagon (based on HttpClient) don't work (exception:
{{Malformed reply from SOCKS server}}).
I suspect that NTLM implementation in HttpClient [is
buggy.|https://codepen.io/ugbandula/post/how-to-configure-maven-to-work-with-ntlm-proxies]
I have successfully tested following patch:
[^0001-WAGON-453-Fix-java.net.useSystemProxies-don-t-work-w.patch]
> java.net.useSystemProxies don't work with wagon-http-lightweight

> In my job, we must use a "corporate proxy" with "NTLM+SPNEGO authentication"
> to access Internet.
> Unfortunately, we haven't got any nominative proxy credential because Windows
> use current user session to authenticate against proxy (we we login to
> Windows session with a smart card).
> The only way for Java application to connect to internet is to launch JVM
> with {{-Djava.net.useSystemProxies=true}} standard parameter.
> It work perfectly with "standard" URLConnection , but unfortunately not with
> wagon-http-lightweight.
