or meio de uma etapa de teste no soapUI, eu quero que todos os arquivos de solicitação e resposta sejam armazenados em um diretório local com a data do sistem

The groovy teststep in soapUI:

def name = context.expand( '${Input#TG}' )

def locatie = context.expand( '${#TestCase#locatie}' )

def createFolder() {
  date = new Date()
  dateFormat = new java.text.SimpleDateFormat('ddMMyyyy')
  shortDate = dateFormat.format(date)
  outputFolder = locatie+shortDate
  createFolder = new File(outputFolder)
  createFolder.mkdir()  
}

def getResponseFilename(name) {
  respFilename = createFolder()+"_"+name+"_response.xml"
}

def getRequestFilename(locatie,name) {
  reqFilename = createFolder()+"_"+ name+"_request.xml"
}

def file = new PrintWriter (getResponseFilename(name))

def response = testRunner.testCase.testSteps
["CheckAdres"].testRequest.response.contentAsString

file.println(response)
file.flush()
file.close()

def file2 = new PrintWriter (getRequestFilename(name))
def request = context.expand('${CheckAdres#Request}')

file2.println(request)
file2.flush()
file2.close()

Estou tendo o erro a seguir
