      If the Powershell step is configured with 'returnStdout: true' and the script does not produce output, than [IO.File]::WriteAllLines fails when converting the temporaryOutput.txt, this causes the job to hang:

      [jaredtest] Running PowerShell script
Cannot contact : java.nio.file.NoSuchFileException: D:\Jenkins-Windows\workspace\jaredtest@tmp\durable-4fe85a3b\output.txt

      Pipeline script to recreate:

      node{
  def output = powershell(returnStdout: true, script: '')
  echo output
}

      Executing `powershellWrapper.ps1` directly in the workspace results in the following error:

      PS H:\> D:\Jenkins-Windows\workspace\jaredtest@tmp\durable-4fe85a3b\powershellWrapper.ps1
