>> The plugin is about a code generator for a home made Java EE6 framework
>> and for instance it will generate very simple xhtml and java classes, so for
>> example the generate-controller plugin would generate
>>
>> *@ViewAccessScoped
>> @Named("personMBean")
>> public class PersonMBean extends AbstractBaseMBean<Person> implements
>> Serializable, ModalObserver {
>>
>>    @Inject
>>     public void setPersonService(PersonService personService) {*//service
>> layer will be generated togheter*
>>         super.setBaseService(personService);
>>     }
>>
>> some other very simple methods
>> }*
>>
>> for the controller-plugin maybe i dont need to understand the model class
>> (just to import it) cause its just a matter of replacing parammeters by the
>> domain object but in the view-plugin it will be necessary for sure.
>>
>> Another concern i have is how to format the generated code? maybe the
>> velocity template could help on that.
>>
>> Ive seen the Arquillian example, how can i clone it and forge project?
>>
>> Thanks again!

>>> Hi Rafael,

>>> There are two things you need to do:
>>> 1) "understand" the Person class
>>> 2) generate new code
>>>
>>>
>>>  1)
>>> You can use a command parameter to get the Person class: @Option(name =
>>> "class", required = true, type = PromptType.JAVA_CLASS) JavaResource
>>> classUnderTest
>>>
>>> JavaResource is a rich file representation of the class.
>>> Now you can use the JavaSourceFacet to get information about the class
>>> itself:
>>>
>>> JavaSourceFacet java = project.getFacet(JavaSourceFacet.class);
>>> JavaSource<?> javaSource = classUnderTest.getJavaSource();
>>>
>>> javaSource has methods such as getPackage() etc.
>>>
>>> 2)
>>> Now you have to generate code. There are two ways to do this, depending
>>> on your needs.
>>> The most elegant way is to use the "JavaParser" builder API:
>>>
>>> JavaClass javaClass = JavaParser.create(JavaClass.class)
>>>                .setPackage(entityPackage)
>>>                .setName(entityName)
>>>                .setPublic()
>>>                .addAnnotation(Entity.class).getOrigin()
>>>                .addInterface(Serializable.class);
>>> Field<JavaClass> id = javaClass.addField("private Long id = null;");
>>> ….
>>>
>>> My experience is that this works best for small classes. If you need to
>>> generate a lot of code it might be better to use a tempting framework such
>>> as Apache Velocity.
>>> You can find an example of this in the code of the Arquillian plugin:
>>> https://github.com/forge/plugin-arquillian/blob/master/src/main/java/org/jboss/seam/forge/arquillian/ArquillianPlugin.java#L93
>>>
>>> You can just add Velocity to your pom file and it will work.
>>>
>>> If you have any more questions, let us know! What kind of plugin are you
