How to format all Java files in an Eclipse project at one time?
提问by sesamegu
I have an old Eclipse project and the code is not well formatted. I'd like to format all the .javafiles according to the settings in Eclipse. I don't want to edit every individual file with Ctrl+Shift+F. Is there a way to format all my files? Perhaps an Eclipse plugin?

Right click on the project root and select Source -> Format. This should work for at least version 3.8.1. and above.
右键单击项目根目录并选择 Source -> Format。这应该至少适用于 3.8.1 版。以上。
If the above does not work, you're probably using an older Eclipse-version. In such case you can select your Source Folders by clicking on them while holding down CTRL, then select Source -> Format from the right-click -menu. Works with package-folders and class files also, in case you don't want to format the entire project.
如果上述方法不起作用，则您可能使用的是较旧的 Eclipse 版本。在这种情况下，您可以通过在按住 CTRL 的同时单击它们来选择源文件夹，然后从右键单击菜单中选择源 -> 格式。也适用于包文件夹和类文件，以防您不想格式化整个项目。

I also had the Java Perspective ON and this was still not working.My eclipse was only formatting css and Html files, but not JAVA ones.
我还打开了 Java Perspective，但仍然无法正常工作。我的日食只是格式化 css 和 Html 文件，而不是 JAVA 文件。
Then, I located this answerthat explains this:
然后，我找到了解释这一点的答案：
You must add Java Facet to the project to allow Java classes to be detected by Eclipse formatter
您必须将 Java Facet 添加到项目中以允许 Eclipse 格式化程序检测 Java 类
Then, you should check on PROJECT-PROPERTIES-PROJECT FACETSand activate the Java facet for the project:
然后，您应该检查PROJECT-PROPERTIES-PROJECT FACETS并激活项目的 Java 方面：
And by right-clicking on top of the PACKAGE-EXPLORERyou will find the SOURCE - FORMAT option, and it will format Java files too.
通过右键单击顶部，PACKAGE-EXPLORER您将找到 SOURCE - FORMAT 选项，它也会格式化 Java 文件。
Be careful, check it′s package explorer, not Project Explorer (click Window-Show View-PackageExplorer)
小心，检查它的包资源管理器，而不是项目资源管理器（单击 Window-Show View-PackageExplorer）

In older versions of Eclipse (Indigo) it works from Package Explorer (not Navigator). Right click the package you wish to format then choose Source -> Format. It will format all classes in that package and its sub-packages.
在旧版本的 Eclipse (Indigo) 中，它可以通过 Package Explorer（而不是 Navigator）工作。右键单击要格式化的包，然后选择 Source -> Format。它将格式化该包及其子包中的所有类。
