## Summary of changes Try to fix the flake we're been seeing in the `dotnet pack` stack of the runner build ## Reason for change Seeing flake like this, which [seems to be happening in `9.0.2xx` of the SDK](dotnet/sdk#17454) ``` The "GenerateToolsSettingsFile" task failed unexpectedly. System.IO.IOException: The process cannot access the file 'D:\a\1\s\tracer\src\Datadog.Trace.Tools.Runner\obj\DotnetToolSettings.xml' because it is being used by another process. at Microsoft.Win32.SafeHandles.SafeFileHandle.CreateFile(String fullPath, FileMode mode, FileAccess access, FileShare share, FileOptions options) at Microsoft.Win32.SafeHandles.SafeFileHandle.Open(String fullPath, FileMode mode, FileAccess access, FileShare share, FileOptions options, Int64 preallocationSize, Nullable`1 unixCreateMode) at System.IO.Strategies.OSFileStreamStrategy..ctor(String path, FileMode mode, FileAccess access, FileShare share, FileOptions options, Int64 preallocationSize, Nullable`1 unixCreateMode) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean useAsync) at System.Xml.XmlWriterSettings.CreateWriter(String outputFileName) at System.Xml.Linq.XDocument.Save(String fileName, SaveOptions options) at Microsoft.NET.Build.Tasks.TaskBase.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(TaskExecutionHost taskExecutionHost, TaskLoggingContext taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask) ``` ## Implementation details Try setting `BuildInParallel=false` [as suggested in this issue](dotnet/sdk#17454 (comment)) ## Test coverage If this build works, we're ok ## Other details The issue appears to be fixed in the .NET 10 SDK: - dotnet/sdk#17454 (comment) I've asked to see if it will backported, but no answer yet 🙄
