在Mac OSX中的Eclipse中缺少JRE

Question

I'm trying to run eclipse on my Mac OS X. I've been doing some Android programming on Eclipse lately, and today wanted to do some development on Java. However, to my surprise, Eclipse says there's no JRE/JDK installed. I don't know how this is possible, since my android projects have worked very well so far, and even now. I've tried the following items:

• Checking java version through the Mac terminal. It says java version "1.8.0_20" is installed. Here's the screenshot.
• I've checked the Java version through the Java Control Panel in System Preferences. Again, same thing:
• I know that when there's no JRE visible in Eclipse, it can be manually entered through the "add" option under preferences > Java > Installed JREs in Eclipse. But although I can find the Contents folder in this path: /Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/home/contents , when I attempt to manually add this in Eclipse, the Java folder under users/library just doesn't show up. I have no idea why this is happening. Here are some screenshots, just in case:

As you can see, the Java folder just doesn't show up under Library in the above screenshot.

• Lastly, I've also tried to hit "Search" in Eclipse (same place as "Add" in one of the screenshots above), but "Search" doesn't find anything at all.

I've gone through existing answers on SO which deal with similar problems. The only thing which I haven't done seems to be about setting a path variable, but they were all in Windows OS, so not sure if it applies in my situation.

I'd really appreciate any help on this.

Update 1: According to what has been pointed out so far, I tried copy-pasting the suggested path. But the error I get is: The home directory does not exist.

Here's the screenshot:

You are trying to find the JRE in a wrong Library directory as Library directory maybe present in more than one place. Just copy paste the jre path in 'jre home' input as

/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/home/contents/Home/jre/

EDIT: To find where is your java installed on Mac, run the following command:

echo $(/usr/libexec/java_home)

it should return something like this:

/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home

append jre to the end of this path to build JRE home path:

/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home/jre
