Im new with appengine, Im, используя appengine version 1.8.7 (также случается со мной в 1.8.6) и пытается добавить maven в проект.App Engine не создает local_db.bin
Когда я настойчив сущность журнала заключается в следующем:
[INFO] nov 07, 2013 5:38:33 PM com.google.appengine.api.datastore.dev.LocalDatastoreService init
[INFO] INFO: Local Datastore initialized:
[INFO] Type: High Replication
[INFO] Storage: D:\Projects\JEE\myapp\tmp\local_db.bin
[INFO] nov 07, 2013 5:38:33 PM com.google.appengine.api.datastore.dev.LocalDatastoreService load
[INFO] INFO: The backing store, D:\Projects\JEE\myapp\tmp\local_db.bin, does not exist. It will be created.
Моя проблема заключается в том, что local_db.bin не создается. И, например, если я попытаюсь выполнить поиск моего периметра, появятся ошибки.
[INFO] java.lang.IllegalArgumentException: Type com.harriague.myapp.dao.entities.Travel is not a known entity type
[INFO] at org.datanucleus.api.jpa.metamodel.MetamodelImpl.entity(MetamodelImpl.java:193)
...
Это моя сущность класс:
package com.harriague.myapp.dao.entities;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Column;
import com.google.appengine.api.datastore.Key;
@Entity(name = "Travel")
public class Travel {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Key travelId;
@Column(name = "name")
private String name;
public Travel() {
}
public Key getTravelId() {
return travelId;
}
public void setTravelId(Key travelId) {
this.travelId = travelId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

Кроме того, если этот проект будет создан плагин appengine eclipse, ничего из этого не происходит, и мне работает код.
Заранее спасибо
Я знаю, что это было некоторое время, но вам удалось получить это работает? –
