I am trying to reverse engineer (generate entity classes) for a complex Oracle database using Hibernate Tools 6.5.2-Final maven plugin.
The hibernate.reveng.xml file is setup to generate entity classes only for all tables (700+) in a specific schema. The maven plugin fails with the following error message:
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.hibernate.tool:hibernate-tools-maven:6.5.2.Final:hbm2java (entity-generation) on project <mavenProjectName>: Execution entity-generation of goal org.hibernate.tool:hibernate-tools-maven:6.5.2.Final:hbm2java failed: component class not found: <packageFromHibernateRevengXml>.MdEintragId
However, if I configure hibernate.reveng.xml to only reverse engineer that one table (MD_EINTRAG) the entity class for the table as well as the class for the composite primary key are created without any issue.
The stacktrace for the failure situation (only last element):
Suppressed: java.lang.ClassNotFoundException: <packageFromHibernateRevengXml>.MdEintragId
