eclipse下使用vim模式编辑，这里我选择的是Vrapper插件。
Vrapper
Vrapper is an Eclipse plugin which acts as a wrapper for Eclipse text editors to provide a Vim-like input scheme for moving around and editing text.
Unlike other plugins which embed Vim in Eclipse, Vrapper imitates the behaviour of Vim while still using whatever editor you have opened in the workbench. The goal is to have the comfort and ease which comes with the different modes, complex commands and count/operator/motion combinations which are the key features behind editing with Vim, while preserving the powerful features of the different Eclipse text editors, like code generation and refactoring.
Vrapper tries to offer Eclipse users the best of both worlds.
插件安装：
