首先，我喜欢intellij。它至少有100个eclipse所缺乏的特性。在重构、重命名、移动和其他已经提到过的东西时，我所说的可靠性和智能程度是任何夸张都无法形容的。

但是，有一件事intellij不允许，而eclipse做到了。它不允许在同一个vm下同时运行多个项目。

当你有独立的前端、中间、核心、代理项目时…等等，它们都必须相互交互，你不能同时快速修改和调试。我目前处理这个问题的唯一方法是使用ant脚本在依赖的项目中部署和更新jar，或者使用maven。

Eclipse允许在一个ide vm实例下调试多个项目。

我在IntelliJ中最喜欢的快捷方式是“转到符号”，这在Eclipse中是没有对应的(我发现的)。CTRL-ALT-SHIFT-N让你开始输入和glob类，方法名，变量名等，从整个项目。

我不记得在Eclipse中是否可以实现字/行/方法/类换行

在Intellij Idea中，您使用Ctrl+W

有很多事情是idea用更简单的方法解决的，或者没有等价的方法:

Autocomplete actions: Doing ctrl+shift+a you can call any idea action from the keyboard without remembering its key combination... Think about gnome-do or launchy in windows, and you've got the idea! Also, this feature supports CamelCasing abbreviations ;) Shelf: Lets you keep easily some pieces of code apart, and then review them through the diff viewer. Local history: It's far better managed, and simpler. SVN annotations and history: simpler to inspect, and also you can easily see the history only for such a part of a whole source file. Autocomplete everywhere, such as the evaluate expression and breakpoint condition windows. Maven integration... much, much simpler, and well integrated. Refactors much closer to the hand, such as loops insertion, wrapping/casting, renaming, and add variables. Find much powerful and well organized. Even in big projects Much stable to work with several branches of a big project at the same time (as a former bugfixer of 1.5Gb by branch sources, and the need to working in them simultaneously, idea shown its rock-solid capabilities) Cleaner and simpler interface... And, simpler to use only with the keyboard, letting apart the need of using the mouse for lots of simple taks, saving you time and giving you more focus on the code... where it matters!

现在，作为开源的…Idea的用户群将呈指数级增长。

就这篇文章而言，我的时机可能有点不对，但我必须做出回应。

我是一个超级日食迷——从它第一次出现就开始使用它。一个朋友告诉我(10多年前)，这将是一个播放器。他是对的。

然而!我刚刚开始使用IntelliJ，如果您还没有见过或使用过变更列表，那么您就错过了编程的天堂。

The ability to track my changed files (on my development branch ala clearcase) was something I was looking for in a plugin for eclipse. Intellij tracks all of your changes for a single commit, extremely easy. You can isolate changed files with custom lists. I use that for configuration files that must be unique locally, but are constantly flagged when I sync or compare against the repository -- listing them under a changelist, I can monitor them, but neatly tuck them away so I can focus on the real additions I am making.

此外，还有一个提交日志插件，可以输出那些没有与错误跟踪软件集成的SCCS的所有更改的文本。将日志粘贴到票据的工作历史记录中可以捕获文件、它们的版本、日期/时间和分支/标记。太酷了。

我打赌，所有这些都可以通过eclipse中的插件(或未来的增强)来支持;然而，Intellij使这变得轻而易举。

最后，我真的很高兴主流对这款产品的喜爱——按键，所以它很痛苦，但很有趣。

我经常使用的一件事是设置断点，然后控制它的功能。(在我的上一份工作中，大多数人都使用Eclipse……我记得我很惊讶，没有人能在Eclipse中找到如何做到这一点。)

例如，可以让断点实际上不停止，而只是将消息记录到控制台。这意味着，我不必用“System.out.println(…)”乱写代码，然后重新编译。
