#Java 1.7

hibernate3-maven-plugin fails with Java 1.7

If you're using Maven's hibernate3-maven-plugin for creating a DDL file from your entities, you might encounter the following error when using Java 1.7:

Execution default of goal org.codehaus.mojo:hibernate3-maven-plugin:2.2:hbm2ddl failed:
An AnnotationConfiguration instance is required

The reason seems to be a broken JRE detection in the Mojo code, which mistakenly assumes that Java 1.7 does not support annotations. However, I haven't checked that in depth.

The fix is pretty easy. In the plugin configuration of the hibernate3-maven-plugin, add an implementation property to the componentProperties like this:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>hibernate3-maven-plugin</artifactId>
  <version>2.2</version>
  <configuration>
    <componentProperties>
      <implementation>annotationconfiguration</implementation>
    </componentProperties>
  </configuration>
</plugin>

This enforces the use of an AnnotationConfiguration instance.
