WARNING MSB5018: Failed to delete the temporary file "C:\Users\cloudtest\AppData\Local\Temp\wjicfzi0.4pf\MSBuildTempcloudtest\tmp141ec17b96ed46fbbe9a45ffeade2592.exec.cmd".

Is an interesting symptom that I certainly don't understand immediately.

@rainersigwald Where did you find another warning?

Find the log in the attachments.

The file is created when _batchFile = FileUtilities.GetTemporaryFileName(".exec.cmd");

Throw the exception when

msbuild/src/Utilities/ToolTask.cs

Lines 809 to 817 in caf06d1

	{
	File.Delete(fileName);
	}
	catch (Exception e) when (ExceptionHandling.IsIoRelatedException(e))
	{
	// Warn only -- occasionally temp files fail to delete because of virus checkers; we
	// don't want the build to fail in such cases
	LogShared.LogWarningWithCodeFromResources("Shared.FailedDeletingTempFile", fileName, e.Message);
	}

Throw the exception in the following code. But couldn't find a way to know which process makes the file not be deleted until now

msbuild/src/Utilities/ToolTask.cs

Lines 809 to 817 in caf06d1

	{
	File.Delete(fileName);
	}
	catch (Exception e) when (ExceptionHandling.IsIoRelatedException(e))
	{
	// Warn only -- occasionally temp files fail to delete because of virus checkers; we
	// don't want the build to fail in such cases
	LogShared.LogWarningWithCodeFromResources("Shared.FailedDeletingTempFile", fileName, e.Message);
	}

Please extend the logging/consider warning suppression for this test and close the ticket.
