You should consider editing the title of your post to be descriptive of what your problem is…
Not really sure what you are trying to do since there is no question in your post. But my assumption is, you are trying to create a server. From your logs, you did not specify a password for the mysql root user so the sdk assumed no password. But I think the mysql account actually has a password hence the sdk cannot connect to it. Trying entering your mysql root password when asked for -DdbPassword. If indeed your root account is not password protected, I’ll advice you set a password for it then trying setting up the sdk again.
