运行 SynchronizeMappings 时出现 PersistenceException

Question

我有使用 apache openJPA 的 eclipse java 项目。 Eclipse 是否有某种缓存需要清理？

我有一个类，UsaState ...映射到 USA_STATE 表。我已将其从数据库、persistence.xml、项目、映射中的引用中删除...没有其他引用的项目，并且我遇到此错误：

问题出在哪里？持久性如何记住该表或实体？ 有必要清洁一下吗？我已经清理过项目几次了...

谢谢

请移至 JPA >= 2.0.0 的较新版本。

尝试重新启动数据库或执行命令刷新表。
