title: Jira export via bash
body: <p>I'm wondering whether it is possible to export data into XML via bash. Of course I could make a dump from database but XML is being choose by procedure of migration which I don't want to change. 
  As far as I have noticed exporting via rest API is not possible. </p>
  
  <p>Is it possible to do it another way? Plug-in? </p>
