有用的 Eclipse 功能？

Useful Eclipse features?

提问by Adam Mika

I have been using Eclipse as an IDE for a short amount of time (about 3 months of full use) and almost every day I learn about some shortcut or feature that I had absolutely no idea about. For instance, just today I learned that Ctrl+3was the shortcut for a Quick Access window.

我将 Eclipse 作为 IDE 使用了很短的时间（大约 3 个月的完全使用），几乎每天我都会了解一些我完全不知道的快捷方式或功能。例如，就在今天，我了解到Ctrl+3是快速访问窗口的快捷方式。

I was wondering what your most useful/favorite Eclipse features are. With the IDE being so big, it would be helpful to learn about the more commonly used parts of the program.

我想知道您最有用/最喜欢的 Eclipse 功能是什么。由于 IDE 如此之大，了解程序中更常用的部分会很有帮助。

This is cool: If someone has emailed you a stack trace, you can copy and paste the stack trace into Eclipse's Console window. You can then click on class names in the stack trace as if your own code had generated it.

这很酷：如果有人通过电子邮件向您发送了堆栈跟踪，您可以将堆栈跟踪复制并粘贴到 Eclipse 的控制台窗口中。然后，您可以单击堆栈跟踪中的类名，就好像您自己的代码已生成它一样。

In terms of actual features, rather than shortcuts, I strongly recommend taking a look at Mylyn.

就实际功能而言，而不是快捷方式，我强烈建议您查看Mylyn。

It essentially skins Eclipse with a task focussed view. It tracks the files you touch when working on a task, and focusses many aspects of the UI onto the resources that it decides are relevant to the job in hand. Eclipse can be somewhat busy to look at, especially with a big multi module project, and Mylyn helps cut through the cruft. The connectivity to issue tracking software and source control repositories is also excellent.

它本质上为 Eclipse 提供了一个以任务为中心的视图。它跟踪您在处理任务时接触的文件，并将 UI 的许多方面集中在它认为与手头工作相关的资源上。Eclipse 可能有点忙，尤其是对于一个大型的多模块项目，Mylyn 帮助解决了繁琐的问题。与问题跟踪软件和源代码控制存储库的连接也非常出色。

In my experience, it polarises opinion amongst those who try working with it, which is probably a sign that it is offering something interesting... Don't mean to sound like a fanboy - it is definitely worth a look though.

根据我的经验，它在尝试使用它的人中引起了两极分化，这可能表明它提供了一些有趣的东西......不要故意听起来像个狂热分子 - 不过它绝对值得一看。

A shortcut that I use everyday is Ctrl+K. In your editor (not only Java file), simply select a text (like a variable, a function, etc.), and then use this shortcut to go to the next occurrence of this text in the current editor. It's faster than using the Ctrl+Fshortcut...

我每天使用的快捷方式是Ctrl+ K。在您的编辑器（不仅是 Java 文件）中，只需选择一个文本（如变量、函数等），然后使用此快捷方式转到当前编辑器中该文本的下一次出现处。它比使用Ctrl+F快捷方式更快......

Note also that you can use Ctrl+Shift+Kto search backwards.

还需要注意的是，你可以使用Ctrl+ Shift+K向后搜索。

CTRL+PAGE DOWN/ CTRL+PAGE UPto switch between opened editors

CTRL+ PAGE DOWN/ CTRL+PAGE UP在打开的编辑器之间切换

CTRL+Eto also switch between opened editors (allows to type the name)

CTRL+E还可以在打开的编辑器之间切换（允许输入名称）

CTRL+Ois extremely important for me. You don't longer need the Outline View then (you can close it which will give you more space). Then, you can type a method name or just the beginning of it and you quickly can get to it. I also use it to inspect what stuff is available. For example: CTRL+Oand then type get ... now I see all getters.

CTRL+O对我来说非常重要。您不再需要大纲视图（您可以关闭它，这将为您提供更多空间）。然后，您可以键入一个方法名称或仅键入它的开头，然后您就可以快速找到它。我还用它来检查可用的东西。例如：CTRL+O然后输入 get ... 现在我看到了所有的 getter。

F3while an element is selected in the code: brings you to its definition or it's source. e.g. used on a method call it brings you into the source code of that method.

F3在代码中选择一个元素时：将您带到它的定义或它的来源。例如，用于方法调用时，它会将您带入该方法的源代码。

CTRL+Mto maximize the current window

CTRL+M最大化当前窗口

As already said, CTRL+3is extremely good. It basically allows you to use Eclipse completely without a mouse. Just type CTRL+3and then package explorer for example.

如前所述，CTRL+3非常好。它基本上允许您在没有鼠标的情况下完全使用 Eclipse。例如，只需键入CTRL+3然后打包资源管理器。

CTRL+F8cycle trough perspectives

CTRL+F8周期低谷观点

CTRL+Lallows to type a line number and brings you directly to that line.

CTRL+L允许输入行号并直接将您带到该行。

CTRL+SHIFT+Gsearches for all references to the selected element in the workspace.

CTRL+ SHIFT+G在工作区中搜索对所选元素的所有引用。

And not a shortcut: In the project settings under Java Editor you can find Save Actions. This allows you to set up the project so that the code is automatically cleaned up and formatted when you save a file. That's very good it safes you from constantly pressing CTRL+Oand CTRL+F.

而不是快捷方式：在 Java 编辑器下的项目设置中，您可以找到保存操作。这允许您设置项目，以便在保存文件时自动清理和格式化代码。这非常好，它可以让您免于不断按下CTRL+O和CTRL+ F。

Eclipse auto refresh isn't on by default so if you make changes to a file outside of eclipse, the change won't be reflected in your build. this is very annoying if you just did an svn/git update/rebase and things aren't working the way they're supposed to.

Eclipse 自动刷新在默认情况下不启用，因此如果您在 Eclipse 之外对文件进行更改，则更改不会反映在您的构建中。如果你只是做了一个 svn/git update/rebase 并且事情没有按照他们应该的方式工作，这会很烦人。

Turn it on in windows->preferences->workspace and tick Refresh Automatically.

在 windows->preferences->workspace 中打开它并勾选自动刷新。

Local History

地方历史

It's a great feature. Eclipse has its own mini-CVS for all files in a project. If you want to revert some change you made, or even restore deleted file - you can right click on the project and select "Restore from Local History".

这是一个很棒的功能。Eclipse 对项目中的所有文件都有自己的迷你 CVS。如果您想恢复您所做的某些更改，甚至恢复已删除的文件 - 您可以右键单击该项目并选择“从本地历史记录中恢复”。

• Ctrl-shift-T, but only type the initial characters (and even a few more) of the class you're looking for. For example, you can type "NetLi" to find NetworkListener
• In the Search window, Ctrl-.takes you to the first leaf of a tree branch
• Alt-/is Word Completion. Slightly different from Ctrl-space

• Ctrl- shift- T，但只输入您要查找的类的初始字符（甚至更多）。例如，您可以输入“NetLi”来查找 NetworkListener
• 在搜索窗口中，Ctrl-.带您到树枝的第一片叶子
• Alt-/是单词完成。与Ctrl——略有不同space
