Constructor Details

#initialize(taskname, antProject, attributes) ⇒ AntTask

Creates an AntTask taskname 

-A String representing the name of an Ant Task. This name should correspond to 
the element name of the Ant xml task (e.g. javac, jar, war, etc).

antProject

-An instance of an AntProject

attributes

-A Hash of task name/values to be applied to the task.

For example:

antProject = AntProject.new()
antTask = AntTask.new('javac', antProject, {:debug => 'on', :verbose => 'no', :fork => 'no'})
