Java 在jhipster中更新实体时，正确的解决方法是什么？

我有一个modelio UML类模型。我一直在更新它，之后我运行jhipster uml.xmi来重新生成实体。我总是收到错误信息。我试图从-jhipster文件中删除entity.json文件，但没有帮助。那么，您能告诉我在开发过程中更新实体的正确解决方法是什么吗？我也尝试运行maven:diff任务，但没有成功

编辑：

我创建了一个新的jhipster应用程序，并从modelio UML类模型中创建了实体。一切正常。然后，我只在模型中添加了一个属性，并从xmi文件中重新生成实体，所有操作系统都再次被破坏

我的工作流程是： 1） 将uml模型另存为xmi文件 2） 运行jhipster uml ac2.xmi-paginate 3） 在intellijIdea中编译我的应用程序 4） 运行maven task:mvn compile liquibase:diff以创建新的变更日志 5） 运行应用程序 6） 查看错误消息：

      classpath:config/liquibase/changelog/20150828220237_added_entity_Employee.xml::20150828220237::jhipster is now: 7:dd10f74a01a95b4e48c592e796a1d352
