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 Editor 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 Editor installation kit.
Custom - the path to an Ant distribution of your choice.
