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

I assume it has something to do with sparse checkout 🤔

[jetersen]

Cannot repro locally with a sparse checkout.

Found the issue

Not sure how this produces null pointers:

@pannikbutton unsure how to repro in Azure, you could try https://github.com/GitTools/GitVersion/pull/1892/files to get a more verbose stack trace

[patrickklaeren]

I too have this issue, I want to provide more information where possible but I was ignored in #1876.

If one could explain how to get more verbose logs from the failure, I'd be happy to forward anything.

Downgrading to to 5.0.1 works. Updating to any newer version breaks.

[jetersen]

hopefully once we have a nupkg of #1892 you should be able to get the detailed stack trace 😅

[arturcic]

@pannikbutton, @Casz, @Inzanit, there package with the stack trace enabled was published, can you try it and provide more details of the error?

[jetersen]

@arturcic see my stacktrace: #1883 (comment)

[patrickklaeren]

Upgraded and got the following stack:

Additionally, I also received a ArgumentNullException, which I assume could be the product of the above error - however it is in a separate project from the one that produced the above stacktrace.

@Casz @Inzanit can you try version 5.1.2-beta.1+12? just add --verbosity normal do the dotnet build. I need the logs as well not only the error

[pannikbutton]

@arturcic @Casz @Inzanit After hours of trial and error and pulling out lots of hair, I can confirm the following:

• The error first appeared in GitVersionTask 5.1.0 (not 5.1.1)
• It only manifests in a private Azure Devops git repo (public repos build successfully every time)

Here are the steps to reproduce the error:

1. Create a new private project
2. Create a new repo
3. Create a new .NET Standard 2.0 class library (I used VS2019 16.3.8 for this)
4. Create and run a new pipeline... [build succeeds]
5. Install GitVersionTask 5.0.1... [build succeeds]
6. Update GitVersionTask to 5.1.0... [build fails]
7. Update GitVersionTask to 5.1.1... [build fails]
8. Update GitVersionTask to 5.1.2-beta1.11... [build fails]
9. Update GitVersionTask to 5.1.2-beta1.12... [build fails]

Screenshots of the build history of two repos, one public (repo1), one private (repo5):

Here is the log from the pipeline after updating GitVersionTask to 5.1.2-beta1.12 in the private repo:

VSBuild Log from Azure Devops using GitVersionTask 5.1.2-beta1.12.txt

Here is a link to the public project in Azure Devops, but since this error only occurs in private projects, you won't see it. But you could still have a look around at stuff like change history and the build config in the yaml file because it is an exact copy of the private repo that produces the error.

That is a great investigation. It looks like when it runs for a private repo it tries to fetch
INFO [11/07/19 9:53:40:20] Fetching from remote 'origin' using

[arturcic]

For azure pipeline it should not fetch by default, so I can go continue the investigation, thanks @pannikbutton

[pannikbutton]

You're welcome, @arturcic. Glad I could be of some help.

[arturcic]

@pannikbutton, @Inzanit, @Casz can you try version 5.1.2-beta.1+18 and confirm it's working for you?

[jetersen]

I can confirm both GitVersionTask and GitVersion.Tool perform as intended now on our Jenkins instance 😄

[emumanu]

it works!

[pannikbutton]

@arturcic Green! So much green everywhere! He he..
Yes. Confirmed. All working on my side.

[jetersen]

Time to 🚢 📦 🚀 v5.1.2 🥇

[arturcic]

Thank you all for the quick feedback and the time you spent helping me figuring out the cause of the error

[arturcic]

Time to v5.1.2

That's the plan
