Examples of PluginContainer

org.apache.maven.model.PluginContainer
Contains the plugins informations for the project. @version $Revision$ $Date$
org.apache.maven.project.PluginContainer
null @version $Revision$ $Date$
org.gradle.api.plugins.PluginContainer

A {@code PluginContainer} is used to manage a set of {@link org.gradle.api.Plugin} instances applied to aparticular project.

Plugins can be specified using either an id or type. The id of a plugin is specified using a META-INF/gradle-plugins/${id}.properties classpath resource.
org.jasen.core.PluginContainer

Holds a plugin and its runtime configuration.

org.rhq.core.pc.PluginContainer
This is the embeddable container that houses all plugins and the infrastructure that binds them together. It contains all the managers such as {@link PluginManager} and {@link InventoryManager}.
This container is controlled by its lifecycle methods ( {@link #initialize()} and {@link #shutdown()}. Prior to initialization, this container's configuration should be set via {@link #setConfiguration(PluginContainerConfiguration)}. If this is not done, a default configuration will be created.
