Hi everyone, We just updated to Jenkins version 2.361.2 and noticed that the JavaScript GUI libraries jQuery and jQuery UI - version 1.2.1 have been deprecated. Has anyone else encountered this issue? If so, could you please share some insights? Thanks, Raanan ---

Take a look at the deprecation, and you see the recommendation is uninstalling the plugin. Ensure updating plugins beforehand, to ensure no dependents are left. ---

> [@eligol](#): > > what do you mean ? if he needs this JS GUI lib so you recommend him to remove it ? 🙂 Yes, that’s what @NotMyFault means. The Jenkins plugin manager recommends that administrators remove deprecated plugins because the plugin is either obsolete, no longer being developed, or may no longer work. In this case, the plugins are obsolete and no longer being developed. As a safety measure, the Jenkins plugin manager won’t allow the administrator to remove a plugin that is a declared dependency of another installed plugin. Both those plugins are unlikely to be a declared dependency of an installed plugin. The [JQuery UI plugin 1.0.2](https://plugins.jenkins.io/jquery-ui/) (last released 12 years ago) has only [two plugins](https://plugins.jenkins.io/jquery-ui/dependencies/) that depend on it. Both those plugins were last released 10 years ago. If either of those plugins are installed, then the plugin manager won’t allow JQuery UI plugin 1.0.2 to be removed. The [JavaScript GUI Lib: jQuery bundles (jQuery and jQuery UI) plugin 1.2.1](https://plugins.jenkins.io/jquery-detached/) (last released 7 years ago) has only [two plugins](https://plugins.jenkins.io/jquery-detached/dependencies/) that depend on it. If either of those plugins are installed, then the plugin manager won’t allow JavaScript GUI Lib: jQuery bundles (jQuery and jQuery UI) plugin 1.2.1 to be removed.
