一个非常有用的特性是能够部分构建Maven反应堆项目，以便只包括您需要的部分。

To make this a little clearer, consider the case of a collection of WAR files with a lot of common resources (e.g. JavaScript, Spring config files etc) being shared between them using the overlay technique. If you are working on some web page (running in Jetty) and want to change some of the overlay code that is held in a separate module then you'd normally expect to have to stop Jetty, run the Maven build, start Jetty again and continue. This is the case with Eclipse and just about every other IDE I've worked with. Not so in IntelliJ. Using the project settings you can define which facet of which module you would like to be included in a background build. Consequently you end up with a process that appears seamless. You make a change to pretty much any code in the project and instantly it is available after you refresh the browser.

非常简洁，而且非常快。

我无法想象在没有它的情况下，在像YUI这样的东西中编写一个返回到DWR/SpringMVC的前端。

结构搜索和替换。

例如，搜索如下内容:

  System.out.println($string$ + $expr$);

其中$string$是一个文字，$expr$是my.package.and.Class类型的表达式，然后替换为:

  $expr$.inspect($string$);

Well, for me it's a thousand tiny things. Some of the macros, the GUI layout in general in Eclipse I find awful. I can't open multiple projects in different windows in Eclipse. I can open multiple projects, but then it's view based system swaps a bunch of things around on me when I switch files. IntelliJ's code inspections seem better. Its popup helpers to fix common issues is nice. Lots of simple usability things like the side bar where I can hover over a hot spot and it'll tell me every implementing subclass of a method or the method I'm implementing and from where.

每当我不得不使用Eclipse时，或者看到别人使用Eclipse时，他们似乎可以做我在IntelliJ中可以做的大部分事情，但它花费的时间更长，而且更笨重。

IntelliJ调试器有一个非常方便的特性，叫做“表达式计算”，这比eclipses pendant好得多。它有完整的代码完成，我认为它通常“更有用”。

在IntelliJ中，您可以通过“最后编辑位置”跳过最后编辑位置的历史。Eclipse也有类似的特性，但是Eclipse只返回到编辑位置的一个级别。

拥有历史记录而不仅仅是Eclipse提供的一个级别是一个很好的生产力特性:它充当了一种自动书签的形式，因为您经常希望跳转回您进行更改的地方。我每天都要使用这个功能几次，当我被要求使用Eclipse来做某些事情时，我感到没有这个功能的痛苦。

可能不是能做/不能做的问题，而是如何做的问题。

例如，两者都有编辑器围绕码头面板的项目，类路径，输出，结构等。但在Idea中，当我开始输入所有这些自动折叠时让我专注于代码本身;在eclipse中，所有这些面板都保持打开，使我的编辑器区域非常小，大约是总可视区域的1/5。所以我必须抓住鼠标，点击来最小化这些面板。在日食中，整天这样做是一种非常令人沮丧的经历。

The exact opposite thing happens with the view output window. In Idea running a program brings the output window/panel to see the output of the program even if it was perviously minimized. In eclipse I have to grab my mouse again and look for the output tab and click it to view my program output, because the output window/panel is just another one, like all the rest of the windows, but in Idea it is treated in a special way: "If the user want to run his program, is very likely he wants to see the output of that program!" It seems so natural when I write it, but eclipse fails in this basic user interface concept.

可能在eclipse中有一个快捷方式(编辑时自动隐藏输出窗口，运行程序时自动显示)，但由于其他几十个功能，快捷方式必须在论坛，在线帮助等中寻找，而在Idea中则更“自然”一些。

这可以重复几乎所有的功能，自动完成，自动换行，快速文档查看，一切。我认为在Idea中的用户体验要比在eclipse中的用户体验愉快得多。那么，“快乐地发展”这句格言就成为现实了。

Eclipse可以处理更快的大型项目(+300个jar和+4000个类)，我认为IntelliJ Idea 8正在处理这个问题。

当然，所有这些都是主观的。我们如何衡量用户体验?
