Add new Ant tasks and types through the Ant preferences page. These tasks and types will be available for
buildfiles running in the Workbench without, having to use taskdef or typedef in the script declaration (For more on
taskdef or typedef see the Ant documentation in http://ant.apache.org).
Select the library where the task or type is declared. If the library is not present on the list, you must add
it to the Ant classpath (see the Related task link below).
