I can not access any external repository using the version 2.2.0. If I go back to 2.1.0 everything works properly.

For example:

mvn -U eclipse:eclipse

[INFO] Searching repository for plugin with prefix: 'eclipse'.
[INFO] org.apache.maven.plugins: checking for updates from central
[WARNING] repository metadata for: 'org.apache.maven.plugins' could not be retrieved from repository: central due

No answer? seems like a serious problem ... has changed the management of http file transfer? Can be a problem similar to that of Eclipse Galileo? http://wiki.eclipse.org/ECF_Filetransfer_Support_for_NTLMv2_Proxies

---------------------------------

maybe you could describe the type of proxy you're trying to use? testing on proxied networks is famously difficult, and many people don't have access to test on certain configurations. It's possible an actual problem slipped through, but I'd expect this isn't beyond our reach to correct using settings.xml configuration. Since Maven 2.2.0 has switched to using a HttpClient-driven http wagon, you might take a look at these pages as starting points, and see how your particular type of proxy is configured:

http://maven.apache.org/guides/mini/guide-http-settings.html
http://hc.apache.org/httpclient-3.x/

John Casey commented on MNG-4228:
---------------------------------

After looking around at this some more, it's possible we'll have to address this in a 2.2.1 release. Not sure what the best strategy is, maybe simply to provide some mapping mechanism for which http wagon to use, then allow folks behind an NTLMv2 proxy to switch over to the lightweight-http solution we used to use. This cuts off some nicer features, but it doesn't look like solutions such as those in [HTTPCLIENT-579|http://issues.apache.org/jira/browse/HTTPCLIENT-579] is going to be an option any time soon.

---------------------------------

Thanks for your reply jhon.
Some developers are not able to configure their corporate proxy. Neither the information about proxy implementation is provided to employees.:(
However, our proxy is NTLMv2, but the company certainly do not want to change it if I can not use maven 2.2.0.

--------------------------------------

Same for me as for Marco. Still not understanding the issue with maven 2.2.0. Why does it work with 2.1.0 and not 2.2.0. I think to understand that the HTTP library has been updated, right? Why does it break NTLM authentication then that was working before?!

I am also using an artifactory server. They use apache's httpclient library and proxy authentication works fine there. So what's the matter here?

Maybe you maven developpers should have a look at http://www.ioplex.com/jespa.html. Maybe it is not your business to make httpclient work, but at least you could suggest a patch or make the guys at apache move to include the lib. I will certainly be benefic for all of use and especially maven

Jean-Marc Borer commented on MNG-4228:
--------------------------------------

It seems we are using NTLMv1: artifactory 2.0.6 uses httpclient 3.x lib which implements NTLMv1. This works fine and authentication is successful. So not (yet) a NTLMv2 issue for me.

Anyway maven 2.2.0 cannot access internet because of Authorization failed: Not authorized by proxy.

I have used the patched lib provided by Konstantin at http://issues.apache.org/jira/browse/HTTPCLIENT-579. You can downloaded it at http://issues.apache.org/jira/secure/attachment/12410908/NTLMV21.RAR 

Then I have rewritten his example see my attached file. Simply drop it to the example dir build and run.

Marco could you try the example to see if this works for you?

Jean-Marc Borer commented on MNG-4228:
--------------------------------------

The solution provided above is based on a patched version of httpclient v3.

If you look at the explanation on page  http://hc.apache.org/httpcomponents-client/ntlm.html concerning httpclient 4.x it uses jcifs implementation for NTLMv2. However they will no longer support the http part of jcifs according to their page http://jcifs.samba.org/src/docs/ntlmhttpauth.html 

I am puzzled here: apache recommends to use a lib that will no longer be supported (at least the http part) and redirect to a commercial implementation jespa http://www.ioplex.com/jespa.html. What sould we do? They don't even explain how to use jespa in httpclient 4.x...
