hibernate-maven-plugin 2.0.0 released!
During one of our other projects ‐ the development of a vertical search-engine for events and locations, which is funded by the mistery of economy of NRW ‐, we realized, that we were in the need of Hibernate 5 and some of the more sophisticated JPA-configuration-options.
Unfortunatly ‐ for us ‐ the old releases of this plugin neither support Hibernate 5 nor all configuration options, that are available for use in the
Fortunatly ‐ for you ‐ we decided, that we really need all that and have to integrate it in our little plugin.
Nearly Complete Rewrite
Due to changes in the way Hibernate has to be configured internally, this release is a nearly complete rewrite. It was no longer possible, to just use the SchemaExport-Tool to build up the configuration and support all possible configuration-approaches. Hence, the plugin now builds up the configuration using Services and Registries, like described in the Integration Guide.
Simplified Configuration: No Drop-In-Replacement!
We also took the opportunity, to simplify the configuration. Beforehand, the plugin had just used the configuration, that was set up in the class SchemaExport. This reliefed us from the burden, to understand the configuration internals, but brought up some oddities of the internal implementation of the tool. It also turned out to be a bad decision in the long run, because some configuration options are hard coded in that class and cannot be changed.
By building up the whole configuration by hand, it is now possible to implement separate goals for creating and dropping the schema.
Also, it enables us to add a goal
update in one of the next releases.
Because of all this improvements, you have to revise your configuration, if you want to switch from 1.x to 2.x.
Be warned: this release is no drop-in replacement of the previous releases!
Not Only For 4, But For Any Version
While rewirting the plugin, we focused on Hibernate 5, which was not supported by the older releases, because of some of the oddities of the internal implementation of the SchemaExport-tool. We tried to maintain backward compatibility.
You should be able to use the new plugin with Hibernate 5 and also with older versions of Hibernate (we only tested that for Hibernate 4). Because of that, we dropped the 4 in the name of the plugin!
Extended Support For JPA-Configurations
We tried to support all possible configuration-approaches, that Hibernate 5 understands.
Including hard coded XML-mapping-files in the
META-INF/persistence.xml, that do not seem to be used very often, but which we needed in one of our own projects.
Therefore, the plugin now understands all (or most of?) the relevant configuration options, that one can specify through a standard JPA-configuration. The plugin now should work with any configuration, that you drop in from your existing JPA- or Hibernate-projects. All recognized configuration from the different possible configuration-sources are merged together, considering the configuration-method-precedence, described in the documentation.
We hope, we did not make any unhandy assumptions, while designing the merge-process. Please let us know, if something wents wrong in your projects and you think it is, because we messed it up!
