working assertions example using standard Java SE with no imports:
thufir@dur:~/jshell$
thufir@dur:~/jshell$ javac App.java
thufir@dur:~/jshell$
thufir@dur:~/jshell$ java -ea App
Exception in thread "main" java.lang.AssertionError
at App.main(App.java:12)
thufir@dur:~/jshell$
thufir@dur:~/jshell$ java App
Dec 21, 2018 1:56:23 AM App main
INFO: false
thufir@dur:~/jshell$
thufir@dur:~/jshell$ cat App.java
import java.util.logging.Logger;
public class App {
private static final Logger LOG = Logger.getLogger(App.class.getName());
public static void main(String[] args) {
boolean isFoo = false;
assert isFoo;
LOG.info(String.valueOf(isFoo));
}
}
thufir@dur:~/jshell$
But, trying to get that to run from Gradle:
thufir@dur:~/NetBeansProjects/HelloAssertions$
thufir@dur:~/NetBeansProjects/HelloAssertions$ gradle clean
> Configure project :

How else should I enable assertions?
