Package org.apache.maven.eventspy

Interface EventSpy

All Known Implementing Classes:

AbstractEventSpy, DefaultArtifactHandlerManager, DefaultPluginValidationManager, DefaultTypeRegistry, EventSpyImpl, LegacyArtifactHandlerManager

public interface EventSpy

A core extension to monitor Maven's execution. Typically, such an extension gets loaded into Maven by specifying the property maven.ext.class.path on the command line. As soon as dependency injection is set up, Maven looks up all implementers of this interface and calls their init(Context) method. Note: Implementors are strongly advised to inherit from AbstractEventSpy instead of directly implementing this interface.

Since:

3.0.2
