In general, the code you added to getBuildArgs() needs to be unit tested.

Please refactor it to a separate method that you can varify in a Spock unit test.

Why you have removed @TempDir annotation and then proceeded with deleting files manually in the cleanup function?

In my local when I work with Tempdir all tests are passing, because windows avoids tempDir path whitespace with a certain encoding (C:\Users\Lahoucine~\AppData\Temp) so no parsing errors will result if I have withespaces in my path.
