JIRA & Jira Agile installation: A step-by-step guide with snapshots

JIRA and JIRA Agile are powerful tools for project management. In my recent work, I tried to install JIRA and JIRA Agile on a Ubuntu Server or Ubuntu Desktop, and though seemingly this is a straightforward process, however to really get it up and running as you expected, this is far from a trivial work.

OsgSnapshotHelper* osh = new OsgSnapshotHelper(pViewer);
delete osh;
osh = NULL;
