The Early Days: Hudson and the Birth of Jenkins
Jenkins wasn’t always known as Jenkins. Its early beginnings trace back to a project called Hudson, which was launched in 2004 by Kohsuke Kawaguchi. Kawaguchi, who was working at Sun Microsystems at the time, started Hudson as a side project with the aim of creating a continuous integration tool that could automate the build, test, and deployment process of software projects. Hudson quickly gained popularity due to its ease of use, flexibility, and the large community of developers who contributed to its growth by creating plugins and extensions.
The Naming and the Philosophy Behind Hudson
The name “Hudson” was chosen by Kawaguchi in honor of the Hudson River in New York. Kawaguchi wanted a name that was distinctive yet simple, and Hudson fit the bill perfectly. The philosophy behind Hudson, which would later become a cornerstone of Jenkins as well, was to provide a platform that could simplify the software development process by automating repetitive tasks. This allowed developers to focus on what they do best: writing code and creating innovative software solutions.
The Transition from Hudson to Jenkins
In 2011, a significant event led to the renaming of Hudson to Jenkins. Oracle Corporation, which had acquired Sun Microsystems in 2010, decided to take control of the Hudson project. This decision was met with resistance from the Hudson community, who felt that Oracle’s involvement would stifle the open-source spirit of the project. As a result, the community decided to fork the Hudson project, and Jenkins was born. The name “Jenkins” was chosen as a nod to the original creator, Kohsuke Kawaguchi, with “Jenkins” being a common English surname that rhymes with “Hudson,” symbolizing continuity and community spirit.
Why the Forking Was Necessary
The forking of Hudson to create Jenkins was a crucial step in ensuring the project’s future as an open-source, community-driven initiative. Oracle’s plans for Hudson were seen as contradictory to the principles of open-source development, with concerns over potential restrictions on community contributions and the direction of the project. By forking Hudson, the community could ensure that Jenkins would remain true to its open-source roots, allowing it to continue growing and evolving based on the needs and contributions of its users.
Post-Fork Developments and Growth
After the fork, both Hudson and Jenkins continued to coexist, but it was Jenkins that truly flourished. The Jenkins community, now free from corporate constraints, could innovate and expand the platform more rapidly. New plugins were developed, the user interface was improved, and support for additional operating systems was added. Today, Jenkins is used by thousands of organizations worldwide, from small startups to large enterprises, and is widely recognized as a leading automation server in the software development industry.
