重新安装 Eclipse 解决问题。
值得注意的是，工作区仍然可用，但您需要重新安装所有插件。
根据日志文件，您的 Eclipse 安装已损坏：
Registry Directory not available: c:\Program Files\eclipse\jee-latest-released\eclipse\p2\org.eclipse.equinox.p2.engine\profileRegistry.
缺少 p2 配置文件 阻止了插件的安装 和卸载（需要配置文件来计算是否可以安装某些东西，如果可以，安装哪些 so-called 个安装单元必须安装哪个版本）。
确保Eclipse安装目录是可写的（在Windows中，c:\Program Files\中的所有内容在默认情况下对于普通用户是不可写的）并且不要删除p2目录。
当安装出现问题时，唯一的解决办法是重新安装 Eclipse。在这种情况下，通过 File > Import: Install > From existing Installation 从旧安装导入现有插件可能也不起作用。
