Package hudson.model

Class UpdateCenter

  • All Implemented Interfaces:
    ModelObject, Saveable, SearchableModelObject, SearchItem, OnMaster, org.kohsuke.stapler.StaplerProxy
    @ExportedBean
public class UpdateCenter
extends AbstractModelObject
implements Saveable, OnMaster, org.kohsuke.stapler.StaplerProxy
    Controls update center capability.

    The main job of this class is to keep track of the latest update center metadata file, and perform installations. Much of the UI about choosing plugins to install is done in PluginManager.

    The update center can be configured to contact alternate servers for updates and plugins, and to use alternate strategies for downloading, installing and updating components. See the Javadocs for UpdateCenter.UpdateCenterConfiguration for more information.

    Extending Update Centers. The update center in Jenkins can be replaced by defining a System Property (hudson.model.UpdateCenter.className). See createUpdateCenter(hudson.model.UpdateCenter.UpdateCenterConfiguration). This className should be available on early startup, so it cannot come only from a library (e.g. Jenkins module or Extra library dependency in the WAR file project). Plugins cannot be used for such purpose. In order to be correctly instantiated, the class definition must have two constructors: UpdateCenter() and UpdateCenter(hudson.model.UpdateCenter.UpdateCenterConfiguration). If the class does not comply with the requirements, a fallback to the default UpdateCenter will be performed.
