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:
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。
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 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 Pathwhat 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.
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 clickAdd Library
- Select
JRE System Library
- Click
Environments
and select thejdk1.7.0_45
Finish
This is what you should see if you did it right:
