Class PluginManager

java.lang.Object

hudson.model.AbstractModelObject

hudson.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.

Get the plugin instance with the given short name.

Parameters:

shortName - the short name of the plugin

Parameters:

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.

getPlugins

doPrevalidateConfig

public net.sf.json.JSONArray doPrevalidateConfig(org.kohsuke.stapler.StaplerRequest req)
                                          throws IOException

Like doInstallNecessaryPlugins(StaplerRequest) but only checks if everything is installed or if some plugins need updates or installation. This method runs without side-effect. I'm still requiring the ADMINISTER permission since XML file can contain various external references and we don't configure parsers properly against that.

Throws:

IOException

Since:

1.483
