Java 当我在liferay中一个接一个地部署两个portlet时，第二个部署的portlet正在liferay中取消部署第一个部署的portlet

当我在tomcat server上逐个部署liferay 6.0.6中的两个portlet时，第二个部署portlet将取消部署第一个部署的portlet，反之亦然，当更改其顺序时：

有解决方案吗？

查看堆栈跟踪

Caused by: com.liferay.portal.OldServiceComponentException: Build namespace abc has build number 20 which is newer than 4

似乎您需要更新版本号

更改特定portlet的

service.properties

或更新

release\uu

表中的内部版本号

你可以参考下面的链接

经过大量挖掘，我找到了解决方案并解决了问题，您可以通过以下步骤解决此问题：

在部署任何portlet之前，需要通过以下命令从servicecomponent表中删除lportal数据库中预部署portlet的条目：例如：delete from servicecomponent，其中buildNamespace='abc'

现在重新部署您的portlet将不会引发异常：由以下原因引起：com.liferay.portal.OldServiceComponentException:Build namespace abc的内部版本号为20，比4新

原因：com.liferay.portal.OldServiceComponentException:生成命名空间yourProject的生成号为x，比y新

解决方案： 转到service.properties

---

更改build.number=x

的原因是：com.liferay.portal.OldServiceComponentException:生成命名空间您的项目具有比y新的生成号x

解决方案： 转到service.properties

更改build.number=x

按照说明操作后，问题没有得到解决。只有console中的错误被删除，但它仍在取消部署以前部署的portlet。请检查它们是否共享相同的命名空间，或者在按照说明操作后，问题没有得到解决。只有控制台中的错误被删除，但它仍在取消部署以前部署的portlet。您能检查它们是否共享相同的命名空间吗
