hibernate4-maven-plugin 1.1.0 released!

Today we released the version 1.1.0 of hibernate4-maven-plugin to Central!

The main work in this release were modification to the process of configuration-gathering.
The plugin now also is looking for a hibernate.cfg.xml on the classpath or a persistence-unit specified in a META-INF/persistence.xml.

With this enhancement, the plugin is now able to deal with all examples from the official
Hibernate Getting Started Guide.

All configuration infos found are merged together with the same default precedences applied by hibernate.
So, the overall order, in which possible configuration-sources are checked is now (each later source might overwrite settings of a previous source):

  1. hibernate.properties
  2. hibernate.cfg.xml
  3. persistence.xml
  4. maven properties
  5. plugin configuration

Because the possible new configuration-sources might change the expected behavior of the plugin, we lifted the version to 1.1.

This release also fixes a bug, that occured on some platforms, if the path to the project includes one or more space characters.

Thanks to Andreas Khutz

hibernate4-maven-plugin 1.0.5 released!

Today we released the version 1.0.5 of hibernate4-maven-plugin to Central!

This release mainly fixes a NullPointerException-bug, that was introduced in 1.0.4.
The NPE was triggered, if a hibernate.properties-file is present and the dialect is specified in that file and not in the plugin configuration.
Thanks to Paulo Pires and and everflux, for pointing me at that bug.

But there are also some minor improvements to talk about:

  • Package level annotations are now supported (Thanks to Joachim Van der Auwera for that)
  • Hibernate Core was upgraded to 4.3.7.Final
  • Hibernate Envers was upgraded to 4.3.7.Final
  • Hibernate Validator was upgrades to 5.1.3.Final

The upgrade of Hibernate Validator is a big step, because 5.x supports Bean Validation 1.1 (JSR 349).
See the FAQ of hibernate-validator for more details on this.

Because Hibernate Validator 5 requires the Unified Expression Language (EL) in version 2.2 or later, a dependency to javax.el-api:3.0.0 was added.
That does the trick for the integration-tests included in the source code of the plugin.
But, because I am not using Hibernate Validator in any of my own projects, at the moment, the upgrade may rise some backward compatibility errors, that I am not aware of.
If you stumble across any problems, please let me know!

Upgraded hibernate-validator from 4.3.2.Final to 5.1.3.Final

Hibernate Validator 5 requires the Unified Expression Language (EL) in
version 2.2 or later. Therefore, a dependency to javax.el-api:3.0.0 was
added. (Without that, the compilation of some integration-tests fails!)

[maven-release-plugin] prepare for next development iteration

hibernate4-maven-plugin 1.0.4 released!

We finally did it.
Today we released the version 1.0.4 of hibernate4-maven-plugin to Central!

This release mainly is a library-upgrade to version 4.3.1.Final of hibernate.
It also includes some bug-fixes provided by the community.
Please see the release notes for details.

It took us quiet some time, to release this version and we are sorry for that.
But with a growing number of users, we are becoming more anxious to break some special use-cases.
Because of that, we started to add some integration-tests, to avoid that hassle, and that took us some time…

If you have some special small-sized (example) use-cases for the plugin, we would appreciate it, if you would provide them to us, so we can add them es additional integration-tests.

[maven-release-plugin] prepare for next development iteration

hibernate4-maven-plugin 1.0.3 released!

Today we released the version 1.0.3 of hibernate4-maven-plugin to Central.

Scanning dependencies

This release of the plugin now supports scanning of dependencies. By default all dependencies in the scope compile are scanned for annotated classes. Thanks to Guido Wimmel, who pointed out, that this was really missing and supported the implementation with a little test-project for this use-case. Learn more…

Support for Hibernate Envers

Another new feature of this release is support for Hibernate Envers – Easy Entity Auditing. Thanks a lot to Victor Tatai, how implemented this, and Erik-Berndt Scheper, who helped integrating it and who supported the testin with a little test-project, that demonstrates the new feature. You can visit it at bitbucket as a starting point for your own experiments with this technique.

Less bugs!

Many thanks also to Stephen Johnson and Eduard Szente, who pointed out bugs and helped eleminating them…

Get your hands on – on central!

hibernate4-maven-plugin 1.0.3 is available in the Central Maven Repository.

"hibernate.exoprt.envers" is no Hibernate-Configuration-Parameter.

Fixed failure when target/classes does not exist when runnin mvn test phase

Thanks to Stephen Johnson

Details from the original email:
---------
The following patch stops builds failing when target/classes (or no main java exists), and target/test-classes and src/tests exist.

So for example calling

mvn test -> invokes compiler:compile and if you have export bound to process-classes phase in executions it will fail. Maybe better to give info and carry on. Say for example they want to leave the executions in place that deal with process-classes and also process-test-classes but they do not want it to fail if there is no java to annotate in src/classes. The other way would be to comment out the executions bound to process-classes. What about export being bound to process-class by default? Could this also cause issues?

In either case I think the plugin code did checks for src/classes directory existing, in which case even call "mvn test" would fail as src/classes would not exist as no java existed in src/main only in src/test. Have a look through the patch and see if its of any use.

Fixed NPE when using nested classes in entities with @EmbeddedId/@Embeddable

Patch supplied by Eduard Szente

Details:
----------------
Hi,

when using your plugin for schema export the presence of nested classes
in entities (e.g. when using @EmbeddedId/@Embeddable and defining the Id
within the target entity class)
yields to NPEs.

public class Entity {

@EmbeddedId
private Id id;

@Embeddable
public static class Id implements Serializable {
....
}

}

Entity.Id.class.getSimplename == "Id", while the compiled class is named
"Entity$Id.class"

Patch appended.

Best regards,
Eduard

Bidirectional Association with @ElementCollection

Have you ever wondered, how to map a bidirectional association from an entity to the instances of its element-collection? Actually, it is very easy, if you are using hibernate. It is just somehow hard to find in the documentation, if you are searching for it (look for chapter 2.4.3.4 in the Hibernate-Annotationss-Documentation).

Hibernate

So, here we go:
Just add the @Parent-annotation to the attribute of your associated @Embeddable-class, that points back to its parent. 

@Entity
class Cat
{
  @Id
  Long id;

  @ElementCollection
  Set kittens;

  ...
}

@Embeddable
class Kitten
{
  // Embeddable's have no ID-property!

  @Parent
  private Cat mother;

  ...
}

Drawback

But this clean approach has a drawback: it only works with hibernate. If you work with other JPA-implementations or plain old JPA itself, it will not work. Hence, it will not work in googles appengine, for example!

Unfortunatly, there are no clean workarounds, to get bidirectional associations to @ElementCollections‘s working with JPA. The only workarounds I found, only work for directly embedded instances – not for collections of embedded instances:


If you want bidirectiona associations to the elements of your embedded collection, it works only with hibernate!

Bugfix: database-parameters for connection were not taken from properties

The hibernate-propertiesfile was read and used for the configuration of
the SchemaExport-class, but the database-parameters from these source were
ignored, when the database-connection was opened.

Bugfix: connection was closed, even when it was never created

Bugreport from: Adriano Machado

When only the script is generated and no export is executed, no database-
connection is opend. Nevertheless, the code tried to close it in the
finally-block, which lead to a NPE.

The Targets EXPORT and NONE force excecution

Otherwise, an explicitly requestes SQL-export or mapping-test-run would be
skipped, if no annotated class was modified.

If the export is skipped, this is signaled via the maven-property
hibernate.export.skipped.

Refactored name of the skip-property to an public final static String

schema is now rebuild, when SQL-dialect changes

Skipping of unchanged scenarios is now based on MD5-sums of all classes

When working with Netbeans, the schema was often rebuild without need.
The cause of this behaviour was, that Netbeans (or Maven itself) sometimes
touches unchanged classes. To avoid this, hibernat4-maven-plugin now
calculates MD5-sums for all annotated classes and compares these instead of
the last-modified value.

hibernate4:export is skipped, when annotated classes are unchanged

Hbm2DdlMojo now checks the last-modified-timestamp of all found annotated
classes and aborts the schema-generation, when no class has changed and no
new class was added since the last execution.

It then sets a maven-property, to indicate to other plugins, that the
generation was skipped.

hibernate4-maven-plugin 1.0 released!

Yeah! We successfully released our first artifact to Central.

hibernate4-maven-plugin is now available in the Central Maven Repository

That means, that you now can use it without manually downloading and adding it to your local repository.

Simply define it in your plugins-section…

  1.0

…and there you go!

hibernate4-maven-plugin

A simple Plugin for generating a Database-Schema from Hibernate 4 Mapping-Annotations

Hibernate comes with the buildin functionality, to automatically create or update the database schema. This functionality is configured in the session-configuraton via the parameter hbm2ddl.auto (see Hibernate Reference Documentation – Chapter 3.4. Optional configuration properties). But doing so is not very wise, because you can easily corrupt or erase your production database, if this configuration parameter slips through to your production environment.

Alternatively, you can run the tools SchemaExport or SchemaUpdate by hand. But that is not very comfortable and being used to maven you will quickly long for a plugin, that does that job automatically for you, when you fire up your test cases.

In the good old times, there was the Maven Hibernate3 Plugin, that does this for you. But unfortunatly, this plugin is not compatible with Hibernate 4.x. Since there does not seem to be any successor for the Maven Hibernate3 Plugin and googeling does not help, I decided to write up this simple plugin (inspired by these two articles I found: Schema Export with Hibernate 4 and Maven and Schema generation with Hibernate 4, JPA and Maven).

I hope, the resulting simple to use buletproof hibernate4-maven-plugin is usefull!

Try it out now!
