Thanks for the detailed report. Since Milestone7 was released, we've upgrade to Apache HttpClient v4.1.2, and we are relying on it's support for proxy authentication.

Any chance you can test out a recent nightly build ([1]http://gradle.org/nightly) and let us know if this issue persists? Then at least we'll know if this will be an issue in Milestone8, due out in a week or so.

[1] http://gradle.org/nightly

I had the same problem with nightly build milestone8 from 1/19/2012

I tried also to set the system property, like systemProp.http.auth.ntlm.domain=\, but it did not help. Is NTLM prxy authorization implemented?

Running the sample project with the latest nightly build leads to a slightly different error output.

BUILD FAILED

Total time: 4.234 secs

I hope somebody solved or solves this. The documentation of Gradle does not help and is probably not complete on this matter.

In 12.3
We could not find a good overview for all possible proxy settings. One place to look are the constants in a file from the ant project. Here a link to the svn view. The other is a Networking Properties page from the JDK docs. If anyone knows a better overview please let us know via the mailing list.

I could not found a better overview of the Networking Properties than the one linked in 12.3.

Two possibilities:
1. NTLM authentication not supported somehow.
2. The http system property settings are not complete or correct.

NTLM and 407 error for milestone7 and for milestone8-nightbuild only the 407. I have the same problem here.

The issue persists, see my replies and the error for the nightbuild is slightly different as showed by lima.

I see earlier in the forum a topic of one month ago also a proxy bug:

> CORE DEV
> Peter Niederwieser (Core Dev) 1 month ago
> GRADLE-1971
>
> I believe the solution chosen was to respect the standard system properties.

Maybe the solution of GRADLE-1971 broke the proxy for NTLM based authentication?

I've just made some changes to proxy authentication: I've tested with a proxy using basic auth, but I don't have access to an environment to test NTLM-based proxy authentication.

These changes are available in the latest [1]nightly build : [2]here.

Any chance you guys can try this out?
(I have not yet added support for NTLM domain as part of the authentication - so if you're supplying a username in the format [domain]
[username] this likely won't work).

[1] http://gradle.org/nightly
[2] http://repo.gradle.org/gradle/distributions-snapshots/gradle-1.0-milestone-8-20120123060500+0100-all.zip

I need to put my username in the format [domain]
[username] and got the following exception with the latest nightly build:

Thanks for the quick response, and for being my tester! I'll have another version for you to try shortly.
If you contact me directly ([1]darrell.deboer@gradleware.com) it might help move things forward more quickly. cheers!
----------------------------------------------------------------------------------------
[1] darrell.deboer@gradleware.com

OK - there's another nightly for you to try: [1]http://gradle.org/nightly

We now support usernames like `MYDOMAIN/user` and `MYDOMAIN\user`. You can also provide the NT domain with the `http.auth.ntlm.domain` system property.

This should work for both
1. proxy credentials : using the `http.proxyUser` and `http.proxyPassword` system properties
2. repository credentials : in a `credentials {}` block in your build script

Please try it out and let me know. Thanks!
----------------------------------------------------------------------------------------
[1] http://gradle.org/nightly

I tried nightbuild from 23-01-2012 (1.0-milestone-8-20120123060500+0100). NB. Maybe the last nightbuild failed?
I tried both with MYDOMAIN/user and MYDOMAIN\user as well as with http.auth.ntlm.domain. There is no dot ('.') in my domain or username (see exception below, which is same as in Lima's last post)

Regards,

Theo.

Is your gradle.properties file accessable? But this looks more like the bug we had earlier, because the properties where not handled in Gradle..... In JIRA GRADLE-1556

On my environment it comes much further and crashes in the NTLMEngineImpl with a NullPointerException.

My sample project can be build using milestone-3 with the same gradle.properties file.

Did you test the latest nightly build 1.0-milestone-8-20120124000030+0100?

Ah I used the old nightly build. I forgot to update my page and the proxy showed me the old. It works for me with milestone-8-20120124000030+0100:

gradle.properties:

systemProp.proxySet=true
systemProp.http.proxyHost=webproxy.sfb
systemProp.http.proxyPort=80
systemProp.http.proxyUser=<my-proxy-username>
systemProp.http.proxyPassword=<my-proxy-password>
systemProp.http.nonProxyHosts=localhost
systemProp.http.auth.ntlm.domain=melkweg

The nightly build works for me now!

Assigning Daz as he's working on it (ticket exported from forums). I though we should track in jira, also.

We are now using JCIFS for NTLM authentication (Milestone 8). This should fix problems with NTLM authentication.
