Spring Roo : database introspect --schema vm1 / Schema vm1 does not exist

I'm new to Spring Roo. I would like to do reverse engineering on mssql database. (jtds is already installed)

But when I running the :

database introspect --schema vm1

I got this :

Schema 'vm1' does not exist or does not have any tables. Note that the schema names of some databases are case-sensitive

picture can tell more than thousand words, take a look at it

What did I wrong ? Thanks ahead.

Use "--schema dbo", the db name is already in your connection URL.
