Ant Preferences

To set Ant preferences, open the Preferences dialog box and go to XML > Ant. This panel allows you to choose the directory containing the Apache Ant libraries (the so-called Ant Home) that Oxygen XML Developer uses to handle Ant build files.

There are two options available:

Built-in - the path to the Ant distribution that comes bundled with Oxygen XML Developer installation kit.
Custom - the path to an Ant distribution of your choice.
