Re: [p2-dev] Tycho 0.16 + Jenkins + NTLM2 proxy

 - cross-posting to p2-dev -

tycho takes the maven HTTP proxy configuration from settings.xml and configures p2 accordingly (via proxyservice API in org.eclipse.core.net)
if resolution and download of maven plugins works but p2 resolution does not, this is a hint that either

a) tycho fails to transfer the proxy info to p2 or
b) p2 / org.eclipse.core.net does not support NTLM proxy authentication

since nobody reported a) yet I doubt this and suspect b)

@p2-devs any hints as to b) above?
https://bugs.eclipse.org/bugs/show_bug.cgi?id=337449#c2  may be related.

@Vincent just in case using apache httpclient v4 would help, this is not up to you; it's a change which would have to be done in p2 (or at least in tycho)
Another thing you should try is to enable advanced HTTP tracing as per [1] and post the traces

Hi Jan,

Thank you for your answer. No I'm not using encrypted passwords for now. I have triple-checked the settings and it's using the proxy (I've tried removing the section completely and the Jenkins fails to download the Maven plugins). Here is the proxy section I'm using (passwords, logins and hosts modified):

  <proxies>
    <proxy>
      <id>bp</id>
      <active>true</active>
      <protocol>http</protocol>
      <username>MYUSERNAME</username>
      <password>MYPASSWORD</password>
      <host>my.proxy.host</host>
      <port>808080</port>
      <!--<nonProxyHosts>local.net|some.host.com</nonProxyHosts>-->
    </proxy>
  </proxies>

Note that I have dropped the wagon-http-lightweight-2.2.jar in the ${MAVEN_HOME}/lib/ext folder of my Maven installation as well as in the folder of Jenkins, just to be sure.

But what I really don't understand is why it works in command line and not in Jenkins. I don't see where the difference is, as I'm using the same version of Maven and the same config file. I don't have enough knowledge of the platform resolution process to understand: where does Maven stop, where does Tycho stop and where does pure P2 code start in the platform resolution process, and how does the chain of transmission of credentials work? I thought that TYCHO-279 had solved the problem, but from the fix I was not able to completely understand the process.

To me it seems that Tycho should configure the proxy/credentials resolution in p2 before invoking it to resolve the platform, so the bug would be in the Tycho/Jenkins interaction, but I may be wrong.

To try the httpclient4, I have to consume the newest version of org.eclipse.ecf.filetransfer.feature, that's right? What would be the recommended way of doing (or is it what I have to ask to p2-dev@xxxxxxxxxxx)?

are you using maven-encrypted passwords?
https://bugs.eclipse.org/bugs/show_bug.cgi?id=394023

are you sure you added proxy credentials in settings.xml [1] ?

other than that you may have hit an NTLM limitation in the outdated apache httpclient 3.x still used by p2.
here is the bug to upgrade to  httpclient v4 which seems to indicate it has better support for NTLM:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=337449#c2 

in this case I suggest to ask on p2-dev@xxxxxxxxxxx for any hints.

Subject: [tycho-user] Tycho 0.16 + Jenkins + NTLM2 proxy

Hi folks,

I'm struggling to configure a Maven build using Tycho on Jenkins behind my company's proxy. I have a set of modules that build perfectly well from the console (I just rebuilt everything using a fresh m2 repo and the build is completely successful). Now I' trying to automate it with Jenkins (see the full env spec at the end of the email). I have configured a Maven build in Jenkins. For the local and global settings, I'm pointing at the exact same settings file I'm using in the console. This settings file contains the proxy definition, with the username, password and everything (and working fine in console). The build is using a private Maven repo.
For my build, I'm using a target platform file (NOT using p2 repositories in the pom.xml), as per the below. This platform is resolved OK when building in console.

The Jenkins build uses correctly the proxy information to download all Maven plugins (including Tycho plugins). However, when Tycho starts resolving the platform, it somehow fails to collect the proxy information (which it should since TYCHO-279 is now closed). I tried all the workarounds described to circumvene TYCHO-279 (using the ECF proxy properties), I tried also using a Nexus repo, nothing worked. I'm a bit screwed new, it seems to be somehow Jenkins-specific but I don't' have a clue what's going on.


Would someone be able to help me investigate the problem?

Environment spec:
- Windows 7
- NTLM2 proxy
- Maven 3.0.4
- JDK 1.6.39 x86_64
- Jenkins v1.501 (out of the box install, running as a Windows service)
- Tycho v0.16
