Package hudson

Class PluginManager

  • All Implemented Interfaces:
    ModelObject, SearchableModelObject, SearchItem, OnMaster, org.kohsuke.stapler.StaplerOverridable, org.kohsuke.stapler.StaplerProxy
    Direct Known Subclasses:
    LocalPluginManager

    @ExportedBean
    public abstract class PluginManager
    extends AbstractModelObject
    implements OnMaster, org.kohsuke.stapler.StaplerOverridable, org.kohsuke.stapler.StaplerProxy
    Manages PluginWrappers.

    Setting default Plugin Managers. The default plugin manager in Jenkins can be replaced by defining a System Property (hudson.PluginManager.className). See createDefault(Jenkins). 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 at least one constructor with the same signature as the following ones:

    1. LocalPluginManager(Jenkins)
    2. LocalPluginManager(ServletContext, File)
    3. LocalPluginManager(File)
    Constructors are searched in the order provided above and only the first found suitable constructor is tried to build an instance. In the last two cases the File argument refers to the Jenkins home directory.

    • Field Detail

      • CUSTOM_PLUGIN_MANAGER

        public static final String CUSTOM_PLUGIN_MANAGER
        Custom plugin manager system property or context param.
      • activePlugins

        protected final List<PluginWrapper> activePlugins
        All active plugins, topologically sorted so that when X depends on Y, Y appears in the list before X does.
      • rootDir

        public final File rootDir
        Plug-in root directory.
      • context

        @Deprecated
        public final javax.servlet.ServletContext context
        Deprecated.
        as of 1.355 PluginManager can now live longer than Jenkins instance, so use Hudson.getInstance().servletContext instead.
      • uberClassLoader

        public final ClassLoader uberClassLoader
        ClassLoader that can load all the publicly visible classes from plugins (and including the classloader that loads Hudson itself.)
      • pluginUploaded

        public volatile boolean pluginUploaded
        Once plugin is uploaded, this flag becomes true. This is used to report a message that Jenkins needs to be restarted for new plugins to take effect.
      • FAST_LOOKUP

        public static boolean FAST_LOOKUP

        Creates the PluginManager to use if no one is provided to a Jenkins object. This method will be called after creation of Jenkins object, but before it is fully initialized.
        Parameters:
        jenkins - Jenkins Instance.
        Returns:
        Plugin manager to use. If no custom class is configured or in case of any error, the default LocalPluginManager is returned.

      • initTasks

        public org.jvnet.hudson.reactor.TaskBuilder initTasks​(InitStrategy initStrategy)

                                                 String fromPath)
      • loadDetachedPlugins

        protected void loadDetachedPlugins()
        Load detached plugins and their dependencies.

        Only loads plugins that:

        • Have been detached since the last running version.
        • Are already installed and need to be upgraded. This can be the case if this Jenkins install has been running since before plugins were "unbundled".
        • Are dependencies of one of the above e.g. script-security is not one of the detached plugins but it must be loaded if matrix-project is loaded.
      • getBundledPluginManifest

        @Deprecated
        @CheckForNull
        public Manifest getBundledPluginManifest​(String shortName)

                                                          throws Exception
        If the war file has any "/WEB-INF/plugins/[*.jpi | *.hpi]", extract them into the plugin directory.
        Returns:
        File names of the bundled plugins. Normally empty (not to be confused with loadDetachedPlugins()) but OEM WARs may have some.
        Throws:
        Exception - Any exception will be reported and halt the startup.

        shortName - the short name of the plugin
        Returns:
        The plugin singleton or null if a plugin with the given short name does not exist. The fact the plugin is loaded does not mean it is enabled and fully initialized for the current Jenkins session. Use PluginWrapper.isActive() to check it.

        pluginClazz - The class that your plugin implements.
        Returns:
        The plugin singleton or null if for some reason the plugin is not loaded. The fact the plugin is loaded does not mean it is enabled and fully initialized for the current Jenkins session. Use Plugin.getWrapper() and then PluginWrapper.isActive() to check it.
