The Apache Ant Task has been added as an independent "application" to the Gradle source structure. It resides in `app/ant-ac`. To test the Ant Task, there is an actual Ant build script available. Run this script from the AppleCommander project directory -- it should figure out paths from that starting position.
The Ant Task testing has been enbedded within the Gradle build for Ant itself and does not need to be run separately. The `app/ant-ac/build.gradle` script reads from the `app/ant-ac/src/test/resources/build-testacant.xml` and executes the tests as part of the testing task.
However, if the Ant script itself is being worked upon, it may be useful to run it outside of the build process. Run the following from the main AppleCommander project directory; note that this requires Ant to be installed and active. As usual, note your Java versions and ensure that Java 11 is active.
$ ant -f app/ant-ac/src/test/resources/build-testacant.xml
