eclipse ide更新检查失败

每次我尝试在EclipseIDE上安装更新时，它都会失败，并出现约束验证错误。例如，eclipse向我显示了需要更新的插件列表，我选择了所有插件，在约束检查失败的情况下，它说一个插件只能安装一个版本

如何修复它

此约束意味着在更新过程中，系统发现插件的不兼容版本：它们依赖于相同的插件

检查Eclipse的错误日志视图，您可以从中找到一条更详细的消息，您可以从中追溯出有问题的插件（这不是确定冲突插件的最简单描述，但我不知道有任何其他类型的p2更新记录器功能）

编辑：在检查错误消息后，我认为更新找到了CDO模型存储库客户端的更新，但没有找到存储库服务器Hibernate组件的更新。我会尝试从添加CDO 4.0对应的更新站点位置（至少如果这是您在COD中用于Hibernate支持的位置）

---

否则，我会尝试（备份Eclipse文件夹后）卸载Hibernate组件，然后进行更新，然后找到您正在使用的CDO Hibernate组件的正确位置。

可能存在依赖关系。逐个更新，请参阅。更新的问题和错误解释，我采取了哪些措施来解决此问题？
