hibernate-tools-maven-plugin

Maven Plugin to generate JPA Entities from an existing database using hibernate-tools.

NOTE: As of hibernate-tools >= 5.3.0.Beta2 (https://github.com/hibernate/hibernate-tools/pull/838) this plugin has been integrated into hibernate-tools itself. Therefore further development of this project is discontinued in favor of the hibernate-tools version.

Development status

Currently the plugin allows database reverse engineering configurations (JDBCMetaDataConfiguration) to export JPA Entities (hbm2java) and Schema Files (hbm2ddl).
