I want to check if Jira Software installed or not because my App haves servlets which containig a functionality that work only with Jira Software like makes a Gantt Chart from Sprints. I do not want to confuse my customers with empty pages without content, etc.
Also I have a problem if user uninstalls the applications Jira Service Desk and/or Jira Software then my App functionality stops working if there is any projects made with Jira Service Desk and/or Jira Software before the uninstallation.
