The absence of the option uses the default value of the property.
For each boolean option, an opposite option is created automatically.
For example, `--no-foo` is created for the provided option `--foo` and `--bar` is created for `--no-bar`.
Options whose name starts with `--no` are disabled options and set the option value to `false`.
An opposite option is only created if no option with the same name already exists for the task.
