Acrimony between proponents of the Hudson continuous integration system and Oracle led to a fork of Hudson, dubbed Jenkins, which lives on as an open source project with a long list of users, including Dell, CloudBees, and Yahoo.
Oracle threw in the towel on Hudson, handing it off to the Eclipse Foundation in 2011. It remains an active project at Eclipse, with Version 3.1 being released last fall. But Hudson founder Kohsuke Kawaguchi, who has moved to Jenkins, vouches for the strength of Jenkins instead: “Jenkins is doing quite strongly. Its adoption has grown 45 percent just the last year alone, whereas I don't see any real activities in the Hudson project anymore. So I consider that chapter behind us.”
