#Jenkins’ history (see Wikipedia articles for Hudson and Jenkins) is really interesting. It was originally #Hudson, at #Sun. When #Oracle bought Sun, around 2010, they sought to trademark the Hudson name, so the majority of the project renamed and moved the project out from under Oracle’s control.
Oracle eventually contributed the Hudson project, trademarks, and other “IP” to the #Eclipse Foundation, but failed to win back the community. The project was relicensed from #LGPL to Eclipse Public License, but that also failed to shift the momentum from Jenkins to Hudson. By 2016 or 2017, the Hudson project announced its demise.
