Eclipse: The specified JRE installation does not exist

Question

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.

Answer 1

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:
