Ant built-in Properties

This is a simple example that illustrates how to find the basedir name, file name, project name, ant version, java version, operating system name, ant home directory name, java home directory name, user home directory name and user name. Ant provides you with certain built-in properties that you may find useful during your build process. The following table shows the property name and it's description.
