Exception in thread "main" java.util.NoSuchElementException

Picking up on your suggestion, I found this Stackoverflow topic and a post on this very forum where this solution is given:

Per default the system.in of your gradle build is not wired up with the system.in of the run (JavaExec) task. You can do the following:

run{
    standardInput = System.in
}

After adding it as the last line of my build.gradle and running gradle <task> the error is still the same though:

Exception in thread "main" java.util.NoSuchElementException
