当我在liferay中一个接一个地部署两个portlet时，第二个已部署的portlet正在取消部署liferay中的第一个已部署的portlet

Question

当我在Tomcat上的Liferay 6.0.6中一个接一个地部署两个portlet时，第二个正在部署的portlet正在取消部署第一个已部署的portlet，反之亦然，更改其顺序时会发生这种情况：

有什么办法吗？

Answer 1

查看堆栈跟踪

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

看来您需要更新内部版本号。

更改service.properties或更新release_表中特定Portlet的内部版本号

您可以参考下面的链接

Answer 2

经过大量挖掘并找到了解决方案，并解决了该问题，您可以通过以下步骤解决此问题：

1. 在部署任何portlet之前，需要通过以下命令从servicecomponent表中删除lportal数据库中预先部署的portlet的条目：例如：DELETE FROM servicecomponent WHERE buildNamespace ='abc';

2. 现在重新部署您的Portlet不会引发异常：由以下原因引起：com.liferay.portal.OldServiceComponentException：构建名称空间abc的构建编号为20，比4更新

Answer 3

由以下原因引起：com.liferay.portal.OldServiceComponentException：构建名称空间yourProject的构建编号x比y更新。

解决方案：转到service.properties更改build.number = x
