Running GitVersion on Docker with Azure Pipelines (Detached Head)

[kabirhussain]

I was able to build and run GitVersion image locally but it fails in my pipeline on Azure Devops. I get the following error message:

An error occurred: It looks like the branch being examined is a detached Head pointing to commit 'xyz'. Without a proper branch name GitVersion cannot determine the build version.

By design Azure Devops pipeline checks out detached head when running build but GitVersion would not work based on above message I received. So I would like to know if there is a solution running GitVersion on docker using Azure pipelines?

As I don't use AzDO myself, I have no idea. But it may be worth trying to ensure the repository is unshallow and that the environment variable Git_Branch is set to the ref (branch or tag) that is being built. This is mentioned in GitVersion's requirements.

@asbjornu Thanks for the response, i have tried adding env variable and still not working. However i get the following error now

[asbjornu]

Hm, I agree this behaviour is strange. From the following line I would expect the version resolution to be successful:

INFO [07/25/21 6:51:05:50] The branch 'origin/feature/develop' has a matching commit.

Are you able to reproduce this behaviour in a test or in a public repository?

[zionyx]

I had the same issue as @kabirhussain's. When running GitVersion task on AzDO isn't possible on Debian 10 agents, resorting to using the docker image didn't work out either.

Docker image used: gittools/gitversion:5.6.10-alpine.3.12-x64-3.1 and gittools/gitversion:5.7.1-debian.10

Output:

I am unable to reproduce this error locally though. I do not have further agent details for now.

[asbjornu]

Your repository seems to be shallow, @zionyx. git fetch --unshallow should fix that.

[zionyx]

Let me try that and get back to you. Thank you @asbjornu

I tried that earlier but faced with auth issues but unrelated to GitVersion though.

[zionyx]

@asbjornu, my repository is a full clone.

fatal: --unshallow on a complete repository does not make sense

Tested on version 5.6.4 without luck.

[asbjornu]

Does git fetch --all help?

[MeikelLP]

@zionyx & @kabirhussain did you guys manage to fix this? I have a very similar error.

[zionyx]

No. But i manage to get GitVersion running without using docker like this:

  - task: gitversion/setup@0
    displayName: Install GitVersion
    inputs:
      versionSpec: 5.6.4

  - task: gitversion/execute@0
    displayName: Calculate SemVer
    inputs:
      updateAssemblyInfo: true
      configFilePath: GitVersion.yml

This is the only version that worked some how.

[MeikelLP]

@zionyx I use the MSBuild task so I have a gitversion locally as well.

I try to build the app in a docker container (docker build) and copy the .git directory into the container. Weirdly enough that does not work. However if I build the app "natively" (without docker) it works like a charm...

[zionyx]

Try mapping the working folder to the docker container as a volume. It works best with git repositories. .git/ folders have symbolic links that may be destroyed with normal copy operations.

Actually the BranchConfigurationCalculator class has not been survived on main. Please try your scenario with the 6.0.0-beta.1 preview release version and re-open this ticket if the problem persists. Thank you very much!
