Interface EventSpy

All Known Implementing Classes:

AbstractEventSpy

public interface EventSpy

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