Over the last years, we were gratefully using a hosted Jenkins instance, which Cloudbees provided to us for free as part of their Dev@Cloud offer. Unfortunately, they have now discontinued this service and it has been shut off today as you might have noticed if you visited the url of the old Jenkins at https://openhab.ci.cloudbees.com/.
Luckily, we were informed well in advance and had the chance to take mitigation actions. Since a few weeks, the openHAB Foundation is running a new Jenkins server at https://ci.openhab.org/, which did all our snapshot and milestone builds over the past weeks already and also builds all PRs that are done against openHAB repos and provides feedback on them. The server runs pretty stable and it is now also covered by our monitoring and status page http://status.openhab.org/. We are planing to upgrade the hardware and take further steps to decrease the build time to make it even more efficient. I would like to thank all openHAB Foundation members as well as all other people, who have donated to the foundation, since all our infrastructure is only possible through your support!
The next major task for our Jenkins will be the openHAB 2.4 release build, which will be published next Monday - so stay tuned!
