试图运行的AppEngine stadard Java代码（这是成功经营的三几个月前），使用mvn appengine:run然后得到错误。 因此，试图在我的其他提到的步骤计算器情况 。 更改后的所有依赖于他们的最新版本（如Hibernate 3几处大的改动冬眠6版），然后得到java.lang.NoClassDefFoundError：组织/休眠/ JPA / HibernateEntityManagerFactory。
问题我注意到，“休眠-EntityManager的”不可用“休眠芯” atrifact，所以我得到了像类错误“组织/休眠/ JPA / HibernateEntityManagerFactory”找不到。 这种“冬眠-EntityManager的”神器已经移动到“休眠核心” atrifact在最近的版本，按照MVN库信息。 但是，当我使用org.hibernate.orm - >冬眠核心的POM文件的依赖，然后得到错误，我也无法找到神器内的休眠-EntityManager的依赖。 所以，想知道什么是另类的依赖，以获得休眠，EntityManager类或在哪里得到它。
下面是详细的错误日志中所强调的，
