Configure Ant build XML file for a very simple IntelliJ Ultimate project.
This Ant build.xml file creates a single executable .jar with a /lib directory inside it that contains the dependency .jars.
The IntelliJ Ultimate generated build.xml must be edited, not replaced, and in the attached project it has been edited some, but there are errors that appear when building the project.
The resulting jar with the /lib dir in it that contains the dependency jars must be able to launch.
You will need IntelliJ Ultimate.
The project is attached.
