如何使用Java 7与Eclipse Indigo 3.7.1 [英] How can I use Java 7 with Eclipse Indigo 3.7.1

问题描述

根据我的了解 Eclipse Indigo 3.7.1 现在应该支持Java 7。

From what I understand Eclipse Indigo 3.7.1 should now have support for Java 7.

我下载了Eclipse 3.7.1。和JDK 1.7.0，并在Eclipse的设置中添加了JRE7。然后我使用JRE7创建了一个新项目，并写了一个简短的Java 7程序：

I downloaded Eclipse 3.7.1. and JDK 1.7.0 and added JRE7 in the settings in Eclipse. Then I created a new project using JRE7 and wrote a short Java 7 program:

public class Test7 {

    public static void main(String[] args) {
        String k = "Hello";
        switch(k) {
        case "World": System.out.println("World Hello");
            break;
        case "Hello": System.out.println("Hello World");
            break;
        }
    }
}

但是当我尝试使用时会收到错误switch语句中的字符串。内容辅助中的错误如下所示：

But I get an error when I try to use a String in a Switch statement. The error in Content assist looks like this:

我做错了什么或者没有Eclipse 3.7.1支持Java 7？您需要更改Eclipse中的任何设置？

Have I done anything wrong or doesn't Eclipse 3.7.1 have support for Java 7 yet? Is there any settings in Eclipse I need to change?

推荐答案

您还必须更改Preferences | Java |编译器| JDK合规性。设置项目的JDK只设置要编译的库和用于运行项目的JDK。

You also have to change the compiler compliance settings under "Preferences | Java | Compiler | JDK Compliance." Setting the JDK for the project only sets the libraries to compile against and the JDK used to run the project.
