Regenerate evolution scripts in play 2

I am still developing first version of my application on play 2. How could I regenerate evolution scripts?

Disclaimer: it will destroy your existing database and create new one!

The auto-evolution will auto-regenerate when:

• you are running your app in the dev mode
• in application.conf you have this line not commented : ebean.default="models.*"
• there is only one file in your evolutions folder and it's 1.sql
• it has this comment at the beginning:
