[Bug] WriteVersionInfoToBuildLog sometimes fails on Windows due to gitversion.properties file lock

[junlinz2]

Describe the bug We are running .NET class library builds on a Jenkins CI system. The MSBuild task WriteVersionInfoToBuildLog will sometimes fail on Windows with the following stack trace:

Each Jenkins job runs from a brand new folder, where the pipeline:

1. Wipes the contents of the job workspace
2. Checks out using git the folder of build scripts
3. Checks out using git the solution (toolkit-foo) that contains a PackageReference to GitVersion.MsBuild
4. Call dotnet build-server shutdown which should clean up any previous build server processes
5. Calls the appropriate build script, which has the line dotnet build --configuration Release --no-incremental --verbosity normal <project>.csproj used to build the project.

The Visual Studio solution and project has a folder structure as follows:

src
|_ Toolkit.Foo
    |_ Toolkit.Foo.csproj
    |_ gitversion.properties (file produced in step 5)
Toolkit.Foo.sln

Expected Behavior

The MSBuild task should be able to consistently access this file for writing/modification without any file locking errors.

Actual Behavior

Usually, the expected behaviour is seen. However, occasionally GitVersion fails to access the file in question, as shown in the stack trace.

Possible Fix

Steps to Reproduce

This issue is difficult to reproduce issue consistently, but:

• Toolkit.Foo.csproj has the following package reference:

<ItemGroup>
   <PackageReference Include="GitVersion.MsBuild" Version="5.12.0" PrivateAssets="contentfiles;analyzers"/>
</ItemGroup>

• Project runs under Jenkins, so JENKINS_URL is set in that environment. I believe that as per https://gitversion.net/docs/usage/msbuild, WriteVersionInfoToBuildLog is called automatically and writes a .properties file due to said environment variable being set.

Context

We are building a series of .NET class libraries sequentially which in turn are depended on by application repos. The class library next in line, that depends on Toolkit.Foo will only start to build if the build job for Toolkit.Foo is marked as successful in Jenkins.

Hi there.

I think you need to investigate this problem in more detail and find the root cause. Why do you think it is a problem in GitVersion?

If I view the code I don't see anything special:

Obviously another process blocking this file. How would GitVersion solve this if the executable is not the owner of the file handler? Do you have maybe concurrent runs? Does a sleep between the steps mitigate this problem?
