I managed to make it work and wrote a blog about it

Hi all,

 

I'm using EclipseLink 2.0.1 to generate entities metamodel so I can use the new Criteria API. I've setup Intellij Idea annotation processing and everything works fine. Now, I need to industrialize the metamodel generation with Maven and I can't make it work. I'm using the apt-maven-plugin as follow :

 

 <build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>apt-maven-plugin</artifactId>
                <version>1.0-alpha-3</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>process</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>                    <factory>org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor</factory>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.eclipse.persistence</groupId>
                        <artifactId>javax.persistence</artifactId>
                        <version>2.0.0</version>
                    </dependency>
                    <dependency>
                        <groupId>org.eclipse.persistence</groupId>
                        <artifactId>eclipselink</artifactId>
                        <version>2.0.1</version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>

 

The problem is that the APT plugin needs an implementation of AnnotationProcessorFactory, so when I run Maven I have the following :

 

[WARNING] warning: Specified factory, 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor', is not an AnnotationProcessorFactory.
[WARNING] warning: No annotation processors found but annotations present.

 

And, indeed, CanonicalModelProcessor doesn't implement AnnotationProcessorFactory.

 

Does anybody know how to generate metamodel classes with Maven ? Am I using the right plugin (APT) ?

 

Thanks,

Antonio
