Checkmk-raw jira-integration

Hi everyone, I’m looking for a way to pair Jira and checkmk. More precisely, I would like to have a ticket created in Jira at a monitoring event. Also an automatic close if a recovery message is available.

At https://forum.checkmk.com/t/check-mk-english-integration-with-jira-to-open-update-close-tickets/14204/4
a plugin by Heinlein support is suggested, which is no longer available on github (i assume tribe29 bought this… to provide this in their enterprise-version).

Does anyone have a copy of the plugin in use?
https://github.com/HeinleinSupport/check_mk/tree/master/notifications/jira_notifications

Or an alternative method (preferably not via mail).
