After several tries I've got the desired result with
//#if ($debug)\
log.finest("my useful debug message");
//#end\
But probably there is a nicer way to do the same thing. I am not an
expert in Velocity.

At least, you have to be very careful.
Just had a simple test
where
public static void main(String[] args){
//#if (true)
System.out.println("logging");
//#end
}
was merged to
public static void main(String[] args){
// System.out.println("logging");
// }
