Eclipse：指定的JRE安装不存在

本文介绍了Eclipse：指定的JRE安装不存在的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 www.oracle/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。

打开Eclipse。

转到首选项。

点击添加

应该弹出一个窗口：

选择标准VM 。

选择目录

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

点击打开

然后完成

右键单击您的项目，然后单击属性

选择 Java构建路径然后单击添加库

选择 JRE系统库

点击环境，然后选择 jdk1.7.0_45

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 www.oracle/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.

Open Eclipse.

Go to Preferences.

Click Add

A Window should popup with this:

Select Standard VM.

Select Directory

Use this path: Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/

Click Open

Then Finish

Right click your Project then click Properties

Select Java Build Path then click Add Library

Select JRE System Library

Click Environments and select the jdk1.7.0_45

Finish

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