# Class Project

java.lang.Object
org.apache.tools.ant.Project

All Implemented Interfaces:
  `ResourceFactory`

public class Project extends Object implements ResourceFactory
Central representation of an Ant project. This class defines an Ant project with all of its targets, tasks and various other properties. It also provides the mechanism to kick off a build using a particular target name.

This class also encapsulates methods which allow files to be referred to using abstract path names which are translated to native system file paths at runtime.
