Eclipse：指定的JRE安装不存在 [英] Eclipse: The specified JRE installation does not exist

问题描述

我以前使用Eclipse配置好，工作正常。但是我刚刚卸载它，并在今天的Mac OS 10.10上再次安装了Eclipse Juno。
但是我不断得到这个错误：
指定的JRE不存在。

我知道这是一个非常简单和常见的问题，我只需要将JRE和/或JDK安装到这个干净的Eclipse中，但是没有办法解决问题。

我在Stack Overflow上广泛搜索：
我看过的帖子包括：
如何在Mac OS X上安装JRE 1.7并将其与Eclipse一起使用？
我遵循所接受的答案，但是在下载来自 http://www.oracle.com/technetwork/java的JDK /javase/downloads/index.html 并安装它，我将通过首选项 - > Java - >安装的JRE将它添加到Eclipse中，但是我没有按预期方式看到它，下面是一个截图我看到什么en我去了首选项 - > Java - >安装的JRE

但截图只是说安装的JRE列表是BLANK，我无法将任何JRE添加到我的Eclipse中。

帮助？

另外，我尝试过别人建议的其他东西：
属性 - > Java构建路径
我在这里看到的是：
JRE系统库OSGi /最小1.2，前面有一个红色十字路口（表示有问题吗？）
所以，我也是阻止这种方式。

解决方案

我也有同样的问题。这是我如何修复它。

1. 打开Eclipse。


2. 转到首选项。


3. 点击添加


4. 应该弹出一个窗口：

5. 选择标准VM 。


6. 选择目录


7. 使用此路径：库/ Java / JavaVirtualMachines / jdk1.7.0_45.jdk / Contents / Home /


8. 点击打开


9. 然后完成


10. 右键单击您的项目，然后单击属性


11. 选择 Java构建路径然后单击添加库


12. 选择 JRE系统库

13. 点击环境，然后选择 jdk1.7.0_45


14. 完成

这是你应该看到的，如果你做的正确：

I used to have Eclipse configured well and work fine before. But I just uninstalled it and installed Eclipse Juno again on my Mac OS 10.10 today. But I kept getting this error: "The specified JRE does not exist."

I know it's a pretty simple and commonly seen problem, I just needed to install JRE and/or JDK into this clean Eclipse, however things didn't get work out.

And I've searched extensively on Stack Overflow: The posts I've looked at including: How to install JRE 1.7 on Mac OS X and use it with Eclipse? I followed exactly what the accepted answer said, but after having downloaded the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and installed it, I was going to add it to Eclipse via Preferences -> Java -> Installed JREs, however, I didn't see it as expected, the following is a screenshot of what I saw when I went to Preferences -> Java -> Installed JREs

But the screenshot just says the installed JREs list is BLANK, I couldn't add any JRE into my Eclipse.

Help please?

Also, I've tried other things that people have suggested: Properties -> Java Build Path what I see here is: JRE System Library OSGi/Minimum-1.2 with a red crossing sign in front of it (indicating something wrong with it?) So, I'm also blocked with this approach.

解决方案

I had the same problem. This is how I fixed it.

1. Open Eclipse.
2. Go to Preferences.
3. Click Add
4. A Window should popup with this:

5. Select Standard VM.
6. Select Directory
7. Use this path: Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/
8. Click Open
9. Then Finish
10. Right click your Project then click Properties
11. Select Java Build Path then click Add Library
12. Select JRE System Library

13. Click Environments and select the jdk1.7.0_45
14. Finish

This is what you should see if you did it right:
