[hibernate-dev] generated code in hibernate

[Brett Meyer]

Hi Jonathan.  If you checkout Hibernate ORM [1] and run "./gradlew generateSources", /target/generated-src will be populated with what Gunnar and Sanne are describing: jaxb, antlr, and logging.

Another category are Java types generated from XML schemas defining several
descriptors such as validation.xml in Hibernate Validator. Generally you'll
find any generated code under target/generated-sources or similar once you
have run a project's build.
