解决Eclipse Plugin-in项目无法右键添加扩展点的问题
闲来无事,学习下开发Eclipse插件的方法,参照博客园[eclipse插件编写](https://www.cnblogs.com/haifeng1990/tag/eclipse%E6%8F%92%E4%BB%B6/)按部就班地学习。但是到了第二步添加扩展点时右键点击无效

仔细查看页面上的内容,发现有警告信息

依据警告信息找到了解决办法[no-schema-found-for-the-org-eclipse-ui-menus-extension-point](https://stackoverflow.com/questions/8366303/no-schema-found-for-the-org-eclipse-ui-menus-extension-point)
