Eclipse中没有永久和物理卸载功能及其插件的机制。物理和永久删除不需要的特性及其插件的过程是一个手动过程，应该在Eclipse未运行时完成。为此，您必须手动从eclipse/features目录中删除与功能相关的文件，并从eclipse/plugins目录中删除其插件。对于要删除的文件要非常小心，并且始终要有Eclipse目录的备份。如果您从这些目录中删除了错误的文件，那么将Eclipse恢复到稳定状态可能会遇到一些问题。单击Basilevs答案开头的链接，了解有关卸载的更多说明 如果没有安装其他第三方插件，最简单、最干净的方法可能是卸载MyEclipse，然后重新安装。这不会影响您的工作区。如果您这样做并安装了其他第三方插件，则需要重新安装它们
请注意，MyEclipse对UML2有一些支持，尽管它已经有一段时间没有升级了。如果您想安装其他UML2工具，最好卸载UML1/2支持。这可以从“帮助->选择组件”页面完成。单击Basilevs答案开头的链接，了解有关卸载的更多说明 如果没有安装其他第三方插件，最简单、最干净的方法可能是卸载MyEclipse，然后重新安装。这不会影响您的工作区。如果您这样做并安装了其他第三方插件，则需要重新安装它们
