Intellij有一个比subversion或Subclipse优秀得多的SVN插件，而且它是有效的!我们在使用Eclipse合并源文件上所浪费的时间是无法想象的。对于IntelliJ，这不是一个问题，因为插件可以帮助你更多。

此外，Subclipse插件也不可靠——我们经常遇到插件认为其他开发人员没有将任何代码签入SVN的情况，但确实存在——CI服务器已经处理了它们!

IntelliJ具有从代码到jspx文档的智能感知和重构支持。

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。

数据流分析:如本文所述，过程间的反向流分析和正向流分析。我的经验是基于Community Edition，它在数据流分析方面做得相当好。当代码非常复杂时，它在少数情况下会失败(拒绝做任何事情)。

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。

对我来说，它是IDEA的maven支持，特别是在版本9中是首屈一指的。项目与maven模型的动态同步非常棒，使开发变得愉快。
