Gitversion fails to get the JSON data

I am working on a project based on this repo

(I would ask the question on it's issues, but it is quite stale...)

I am trying to do the task, to create the the pipeline, but it fails within this step:

          - pwsh: |
              dotnet tool install --global GitVersion.Tool

              Write-Output ">>>>>>>>>>>>>>>>"
              dotnet-gitversion
              Write-Output "<<<<<<<<<<<<<<<<"

              $gitVersionObject = dotnet-gitversion | ConvertFrom-Json
              $gitVersionObject.PSObject.Properties.ForEach{
                  Write-Host -Object "Setting Task Variable '$($_.Name)' with value '$($_.Value)'."
                  Write-Host -Object "##vso[task.setvariable variable=$($_.Name);]$($_.Value)"
              }
              Write-Host -Object "##vso[build.updatebuildnumber]$($gitVersionObject.FullSemVer)"
            displayName: Calculate ModuleVersion (GitVersion)

I have tracked down that this is an issue with the gitversion (tried the gitversion task too from the AZ tasks)

INFO [09/23/22 11:30:47:85] Skipping fetching, if GitVersion does not calculate your version as expected you might need to allow fetching or use dynamic repositories

How can I get around this?

Thanks

Solution

  • The cause of the issue could be related to the fetch depth of the Pipeline repo.

    Try to set the "fetchDepth" to "0" in YAML Pipeline. By default, the Shallow fetch of the pipeline repo is 1.

    For example:

    steps:
    - checkout: self
      fetchDepth: 0
    - pwsh:xxx

    Or you could edit "YAML Pipeline" -> "More actions" -> "Triggers" -> "YAML" -> "Get sources" -> unselect "Shallow fetch".
