GitVersionTask 5.1.0 - Error in Azure Devops private repos: Value cannot be null. Parameter name: source

[pannikbutton]

This might be related to #1876. But I'm not sure, so I created a new issue.
When building with a VSBuild step inside Azure Devops pipelines, the build fails with this error:

GitVersionTask.targets(10,9): Error : Value cannot be null.
Parameter name: source

Log from Azure Devops pipeline.txt

As with #1876, downgrading to 5.0.1 is a workaround.

@pannikbutton can you check the 5.1.2-beta.1+8 version if it fixes the issue?

[pannikbutton]

@arturcic I have tried GitVersionTask 5.1.2-beta1.8. However, the same error occurs.

I also tried the 5.1.2-beta.1+8

And I experienced this error on Jenkins

[jetersen]

FYI using 5.1.2-beta1.8 of GitVersion.Tool passes but GitVersionTask fails.

[arturcic]

@Casz, @pannikbutton can any of you create a repo that reproduces this error? or if it's a public repo I can have a look?

[jetersen]

I think any csproj will do as long as the checkout is done by Jenkins git plugin or Azure DevOps

[jetersen]

I do have a basic GitVersion repo I could share and also confirm that is the case.

[arturcic]

We do have artifacts testing as part of the build pipeline, and we test the msbuild task inside of a container, by running dotnet build, and the pipeline runs on Azure Pipelines, so can it be related to Jenkins?

[arturcic]

see this https://dev.azure.com/GitTools/GitVersion/_build/results?buildId=1221&view=logs&j=06b13910-90cf-591b-131c-f7868e92de8b&t=9ae9394c-29d7-5a09-210f-610db1f7d869&l=163

[arturcic]

and this is the test project https://github.com/GitTools/GitVersion/tree/master/test, that we use when running in pipeline

[arturcic]

I do have a basic GitVersion repo I could share and also confirm that is the case.

Please share it and add steps to reproduce
