As far as I know, constraints are not part of JDL in a general manner. You can define such things as validations. But as for the Domain, the unique constraint is not that general anymore, it is a database level constraint, where it has to be applied.

For this, JHipster includes Liquibase. So you can find the changelog, defining the entity constraints in "src/main/resources/config/liquibase", and add a

to that changelog.

If you already started your application used h2 disk persistent databse, make a mvn clean / ./gradlew clean before starting your app again.
