Problem Definition

As an admin, I am constantly doing JIRA modifications which require re-index (building new projects, adding custom fields). Notification pop-up is constantly in the way after this operations:

There is a cron job that runs every night to reindex JIRA, so I'm not going to run re-index each time.

Suggested Solution

I would like to have a option to suppress pop-up for some period of time or make it disappear after short period of time (1 s).

Workaround

• Change CSS and hide notification pop-up by adding following CSS into Announcement Banner (Administration > System > Announcement Banner)
  Announcement Banner

  <style type="text/css">
      #aui-flag-container {
          display:none !important;
      }
  </style>
  

  Note: this modification is not supported by Atlassian. It will hide other notifications also.

Notes

These notification is pushed by JIRA backend itself to UI:

require(['jquery', 'jira/flag'], function ($, flag) {
            flag.showInfoMsg(null, "We recommend ... ", { dismissalKey: "com.atlassian.jira.reindex.required" });

UI analyses com.atlassian.jira.reindex.required key and hide notification pop-up if key is present.
This key could be pushed from backed to UI as part of page (JIRA backend makes this decision at com.atlassian.jira.user.flag.FlagDismissalServiceImpl ):

WRM._unparsedData["com.atlassian.jira.jira-header-plugin:dismissedFlags.flags"]="{\"dismissed\":[\"com.atlassian.jira.reindex.required\",\"com.atlassian.jira.baseurl\",\"com.atlassian.jira.tzdetect.-21600000,-18000000\"]}";
