MavenPluginManager
@Component(role=MavenPluginManager.class) public class DefaultMavenPluginManager extends Object implements MavenPluginManager
Provides basic services to manage Maven plugins and their mojos. This component is kept general in its design such that the plugins/mojos can be used in arbitrary contexts. In particular, the mojos can be used for ordinary build plugins as well as special purpose plugins like reports.- Since:

KEY_EXTENSIONS_REALMS
public static final String KEY_EXTENSIONS_REALMS
PluginId => ExtensionRealmCache.CacheRecord map MavenProject context value key. The map is used to ensure the same class realm is used to load build extensions and load mojos for extensions=true plugins.
