Looking at our releases Jenkins plugins and playing with the jenkins-plugin-manager there are a few plugins we should be able to remove entirely:
| Bootstrap 4 API | was probably a dependency of Junit which is now using Bootstrap 5 API | |
| No more bundled as of 2.303.1 | ||
| GitHub, GitHub API, GitHub Branch Source | We do not use GitHub | |
| JavaScript GUI Lib: Handlebars bundle plugin | ||
| JavaScript GUI Lib: jQuery bundles (jQuery and jQuery UI) plugin | ||
| Multijob | Deprecated, no jobs using it | |
| Oracle Java SE Development Kit Installer | Built-in plugin | |
| No more bundled as of 2.303.1 | ||
| WMI Windows Agents Plugin | Built-in plugin | |
| Git server | installed by Pipeline: Deprecated Groovy Libraries itself installed by Pipeline 2.6 | |
Some are probably left over transitive dependencies. The aim is to slightly reduce the scope of plugins we will have to manage via the jenkins-plugin-manager.
