migrate4j strives to be Java's answer to the db:migrate rake task in Rails. While it isn't a replacement or clone, it does provide simple configuration, flexibility and ease of use in a database migration tool.
A nice framework for managing the migration of your DB schema using a Java API, while still allowing SQL if necessary. It's still in the early stages, but production ready.
Useful, simple and easy to use.
A great way of keeping your db schema in sync with your Java code base. A little rough around the edges, but improving all the time. Most of my gripes are already fixed in the svn trunk. Most Java coders don't like SQL much. Your team will thank you for choosing this tool, and the perennial 'wrong schema version' problems will disappear to boot. Well done!
