Hiding the Internal Targets
Ant scripts are very modular. Many of the Ant tasks within an Ant script are not meant to be executed directly. These targets are called internal targets. During normal development, it's a common practice to hide the internal targets to reduce the clutter you see in the list of available targets. This allows you to focus on Ant tasks that are actually usable.
