The following build configuration shows how to enhance JPA entities at compile time. Please consult the OpenJPA documentation for more details on compiletime enhancement versus runtime enhancement.
The openjpa:enhance mojo will typically be called in the process-classes
phase.
Please note that the tmpClassLoader defaults to false
to make sure that classes in depending artifacts (like enums in interfaces) can be parsed by the PCEnhancer.
