Instances of classes that implement this interface can register
to be also notified when things happened during a subbuild.
A subbuild is a separate project instance created by the
<ant> task family. These project instances will
never fire the buildStarted and buildFinished events, but they will
fire subBuildStarted/ and subBuildFinished. The main project
instance - the one created by running Ant in the first place - will
never invoke one of the methods of this interface. |
