How to include a custom annotation on generated classes

I’d like to add the immutables annotation (@Value.Immutable) to generated classes. Are there any other options to do so besides modifying the jsonschema2pojo source and implementing a custom Annotator? Thanks!

This is an older example, but here is a custom type annotator I was using to deserialize java.util.Set as java.util.LinkedHashSet, before this feature was merged into the project.

import java.util.LinkedHashSet;
import java.util.Set;

import org.jsonschema2pojo.AbstractAnnotator;

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.sun.codemodel.JDefinedClass;
import com.sun.codemodel.JFieldVar;

public class CustomTypeAnnotator extends AbstractAnnotator {

  @Override
  public void propertyField( JFieldVar field, JDefinedClass clazz, String propertyName, JsonNode propertyNode ) {
    super.propertyField(field, clazz, propertyName, propertyNode);

    if( field.type().erasure().equals(field.type().owner().ref(Set.class)) ) {
      field.annotate(JsonDeserialize.class)
        .param("as", LinkedHashSet.class);
    }
  }
}

I built this in its own module and then included it in my configuration:

        <plugin>
          <groupId>org.jsonschema2pojo</groupId>
          <artifactId>jsonschema2pojo-maven-plugin</artifactId>
          <version>0.4.4</version>
          <dependencies>
            <dependency>
              <groupId>ANNOTATOR_GROUP_ID</groupId>
              <artifactId>ANNOTATOR_ARTIFACT_ID</artifactId>
              <version>ANNOTATOR_VERSION</version>
            </dependency>
           ...
          </dependencies>
          <configuration>
            <customAnnotator>FULLY_QUALIFIED_ANNOTATOR_NAME</customAnnotator>
            ...
          </configuration>
          ...
        </plugin>

This was enough to get custom annotations on the java.util.Set fields. Hope this helps!

Either of these methods could be used to add a class level annotation:

void propertyOrder(JDefinedClass clazz, JsonNode propertiesNode);
void propertyInclusion(JDefinedClass clazz, JsonNode schema);
