LibGit2Sharp.LibGit2SharpException: Request failed with status code: 401 / Unsupported URL protocol

[babadofar]

Hi,
I'm trying to use GitVersionTask, 3.0.0-beta2 with TeamCity 8.0.5
Have set the environment variables GITVERSION_REMOTE_PASSWORD and GITVERSION_REMOTE_USERNAME as explained here: https://github.com/ParticularLabs/GitVersion/wiki/MSBuild-Task-Usage

We normally use ssh to checkout from bitbucket, but I tried using https as well, they give slightly different error messages, both seem to indicate connection/authentication failures.

ssh error message:

To the best of my knowledge, SSH is currently not supported in libgit2, therefore not supported in GitVersion.

libgit2/libgit2sharp#852

You can find some more information about this here:

#38

Therefore, you best option would be to use HTTPS connection. Perhaps open another issue specifically for that?

[babadofar]

Thanks, it definitely helped when I stopped using ssh.
Got it working now!

[gep13]

👍

[babadofar]

Hm. Loooking further into this, we are using the git checkout hack as proposed in this issue #21 So there should be no need for gitVersionTask to checkout branches, they are already there.
What we really need seems to be the nofetch option, as described here #431
Next release?

[gep13]

Yip, this has been merged, and should be in the next release:

#432

If you want to, you can compile from source and give it a try if you wanted to try this out.

Our build configuration using GitVersionTask in TeamCity looks like this:

• General Settings
  • Build number format: %system.GitVersion.FullSemVer%
• Version Control Settings
  • VCS checkout mode: Automatically on agent
• VCS Root
  • Fetch URL: https://user@bitbucket.org/repository.git
  • Authentication method: Password
  • Username: user
  • Password: *****
• Parameters
  • system.GitVersion.FullSemVer: ''
  • env.GITVERSION_REMOTE_USERNAME: user
  • env.GITVERSION_REMOTE_PASSWORD: *****

I believe this is everything required to get all git operations to work with GitVersion. Does your build configuration look identical to this, @babadofar?

[babadofar]

Thanks Asbjørn!
Very nice overview of the settings needed for TeamCity
I did manage to get it working, using https as method to connect to
bitbucket. The problem is, our entire system is set up to use ssh.
Of course, the right thing to do here is to start porting projects. Then we
could finally get rid of the infamous "checkout all branches" powershell
hack :)

@babadofar, even better would be for libgit2 to get SSH support, since SSH is unquestionably preferable when it is available. But until then, HTTPS is a compromise we're willing to accept since the value GitVersion gives us far outweighs HTTPS' downsides. 😃

@asbjornu said...

Agreed! 👍

We are having this problem in our TeamCity setup. I am accessing the repo using SSH, and I get a very similar callstack:

[chris1248]

Huh: I did this:

add a parameter called env.Git_Branch with value %teamcity.build.vcs.branch.<vcsid>%

and the problem went away. Cool! No idea why it didn't throw a better exception, but this will work for now.
