Cómo resolver: "error: no se puede encontrar la class de símbolo …" después de convertir la class Java en Kotlin?

Intento comenzar con Kotlin convirtiendo algunas classs de Java de mi proyecto en Kotlin y crear un proyecto mixto Java / Kotlin. Para configurar el entorno hice lo siguiente:

  1. Descargó la última versión del complemento de Kotlin (1.0.2);
  2. En el nivel superior de gradle.plugin, agregué: classpath "org.jetbrains.kotlin:kotlin-android-extensions:1.0.2" en la sección de dependencies;
  3. En el complemento gradle de mi module, he agregado: compile "org.jetbrains.kotlin:kotlin-stdlib:1.0.2" en la sección de dependencies;
  4. Escogí la class POJO que quería convertir a kotlin, seleccionada desde el menu Código -> Convertir file Java a Kotlin File;
  5. Después de eso, todas las classs de Java que estaban importando la class convertida comenzaron a mostrarse: error: cannot find symbol class Chat . A continuación se encuentran la class original, la class convertida y el logging:

Clase original de Java:

 package br.com.gogame.model; import com.google.gson.Gson; import com.orm.SugarRecord; import com.orm.dsl.Ignore; import java.io.Serializable; import java.util.List; import br.com.gogame.model.enums.ChatType; /** * Created by edgar on 11-Apr-16. */ public class Chat extends SugarRecord implements Serializable { private String title; private String thumbnail; private ChatType chat_type; private long chat_id; private int num_of_members; private long user_id; @Ignore private List<Long> users; public Chat() { } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getThumbnail() { return thumbnail; } public void setThumbnail(String thumbnail) { this.thumbnail = thumbnail; } public ChatType getChat_type() { return chat_type; } public void setChat_type(ChatType chat_type) { this.chat_type = chat_type; } public long getChat_id() { return chat_id; } public void setChat_id(long chat_id) { this.chat_id = chat_id; } public int getNum_of_members() { return num_of_members; } public void setNum_of_members(int num_of_members) { this.num_of_members = num_of_members; } public long getUser_id() { return user_id; } public void setUser_id(long user_id) { this.user_id = user_id; } public List<Long> getUsers() { return users; } public void setUsers(List<Long> users) { this.users = users; } @Override public String toString() { Gson gson = new Gson(); return gson.toJson(this, Chat.class); } } 

Clase de Kotlin convertida

 package br.com.gogame.model import com.orm.SugarRecord import com.orm.dsl.Ignore import java.io.Serializable import br.com.gogame.model.enums.ChatType /** * Created by edgar on 11-Apr-16. */ class Chat : SugarRecord(), Serializable { var title: String? = null var thumbnail: String? = null var chat_type: ChatType? = null var chat_id: Long = 0 var num_of_members: Int = 0 var user_id: Long = 0 @Ignore var users: List<Long>? = null }
