Jira - Need to download the attached file in Jira Listener

[Ramkumar D]

I would like to write a Listener script that will trigger on Issue Updated event. The Listener script should download the newly attached file to the issue and upload it to another webserver.

I am a little confused on what might go where.  You are talking about downloading a newly attached file, which does not tell us where things should land.

Basically, the request is for a listener script that will be triggered whenever any jira issue is updated. The functionality of the script should be like:
1. It should download the newly added attachment from a jira issue(attached in the respective jira issue) in any temporary location for time being.

2. Upload it to another webserver.

3. Delete that attachment(from that temporary location).
