How to specify the host ?

[gilles6]

$ php artisan db:spy dp:../mysql-connector-java-5.1.44-bin.jar
Unknown connection 'dp:../mysql-connector-java-5.1.44-bin.jar'. Command will fail unless you provide DB credentials.

 Enter database name:
 > blog

 Enter database username:
 > root

*** Required parameter 'host' (hostname[:port] host where database resides with optional port) was not specified.  It is required for this database type. ***
Something went wrong

The parameter you need to pass is not the JAVA connector file path, but the name of your database connection in your Laravel configuration, that is, the value of the default key of your config/database.php file.

To provide the JAVA connector file path you need to edit the config/spy.php file.
