## 问题 ##

在写文章[Eclipse插件（RCP）项目搭建][Eclipse_RCP]时遇到了异常  
`org.osgi.framework.BundleException: Could not resolve module: org.eclipse.wst.xml.core`

问题发生在启动过程，启动时成功的，但控制台始终报这个错误。

## 解决 ##

**解决方式一**：

1.  停止启动的应用
2.  关闭Eclipse
3.  删除工作空间中`.metadata\.plugins\`下所有插件
4.  重启Eclipse
5.  重新导入项目
6.  启动，后这个问题就不存在了

**解决方式二**：

1.  停止启动的应用
2.  关闭Eclipse，重新启动，启动时**指定新的工作空间**
3.  导入项目

## 分析 ##

我使用了两个版本的Eclipse，分别是2020-06版和2021-12版。启动时给它们指定了相同的工作空间，并且都用他们尝试建同一个项目。因此猜测在这个工作空间中插件比较混杂，Eclipse加载的插件信息也就有问题了。

## 总结 ##

Eclipse 工作空间的信息对Eclipse运行时环境影响比较大，如遇到一些莫名问题时，可以采用本文介绍的方式尝试。

## 附： ##

具体信息如下：
