Publishing Experimental Plugin Releases

View the index of available developer guides

To simplify delivery of beta versions of plugins to interested users, the Jenkins project published an experimental update center. It includes alpha and beta versions of plugins, which aren’t usually included in the regular update center.

Creating Experimental Plugin Releases

Plugin releases that contain alpha or beta in their version number will only appear in the experimental update site, not in the regular update center. The experimental update center also serves regular releases. Newer releases hide older releases in all update centers. For example, the release of version 1.4 will hide 1.3-beta-2 from the experimental update center.

Note that only alpha and beta strings in the version number will publish to the experimental update center. Other version strings like proto, rc, and unstable will appear in the regular update center.

Using the Experimental Update Center

Users who are interested in downloading experimental plugin releases can go to Plugin Manager, then to the Advanced tab, and configure the update center URL https://updates.jenkins.io/experimental/update-center.json. Submit, and then select Check Now. Experimental plugin updates will be marked as such on the Available and Updates tabs of the Plugin Manager.

Once you install the beta plugins that you wanted, you can switch back to the default https://updates.jenkins.io/update-center.json update center URL.
