What is the difference between the gradle options "--daemon" and "-daemon", double dash versus single dash?

What is the difference between the gradle options “–daemon” and “-daemon”, double dash versus single dash? The single dash prints information that it is connecting to daemon and running gradle task on the daemon but the double dash does not print anything and it is same as executing without daemon option. The double dash is documented but single dash documentation not exists :frowning:

I think running gradle with “-daemon” is the same as running it with “-d” which means running it with debug logging enabled. Maybe Gradle should be more helpful here and complain about the wrong parameter here.
