I need to generate Liquibase Change-set for my JPA entities. How can I do that?

Question

I have tried the following

liquibase:generateChangeLog - It generated the change log from my db.I need to generate the change-log from my JPA entities.

liquibase:diff - It generates the change log for the difference between my db and JPA entities. I cannot say that my db is always empty and I want to generate the create scripts which can be applied on fresh db.

How can I use Liquibase to generate the scripts based on my JPA entities only ?

Note : I am ok in providing the details about my db such as url,driver etc

If your IDE of choice is IntelliJ IDEA, I'd recommend using the JPA Buddy plugin to do this. It can generate Liquibase changelogs by comparing your Java model to the target DB.

Once you have it installed and have Liquibase as your Maven/Gradle dependency, you can generate a changelog like this:

You have to create a schema with persistence properties according to Database Schema Creation and then use the Liquibase generateChangeLog command.
