Eclipse not recognizing JVM 1.8

Question

Still trying to get Eclipse IDE to work and running into Incompatible JVM error. I followed the steps here: I installed Java 7 but Eclipse keep saying that 1.6 is not suitable for this product

But unfortunately to no effect. Running OSX 10.9.5 and uninstalled the out-of-the-box version of Mac. The new version of Java seems to show up in the System Preferences. Please see attached screen capture. I've even done some of the basics like restart my computer, etc. Maybe there are other modifications I need to make to other files. I'm comfortable with Terminal but new to Eclipse and Java. Thanks in advance!

Answer 1

I have had the same problem as noted above. I could not get Eclipse to install because of Java incompatibilities. The sequence I followed goes like this:

1. Upgraded to MAC OS Sierra
2. Downloaded the Eclipse installer but was prompted that I needed to instal a legacy Java.
3. Installed Java 1.6
4. Was unable to install Eclipse and was prompted that I needed Java 1.7 or greater. Downloaded and installed Java 1.8
5. Ran the terminal code 'java -version' // this will check your jre version. This showed returned Java 1.6 despite the fact that I had upgraded to 1.8. The Java version listed in the Java control panel said 1.8
6. Tried multiple downloads of eclipse and Java and multiple restarts always with the same result.
7. Visited the Oracle web page noted above: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html I could not find the above reference to 8u73 and 8u74 but I did find and option to download 1.8.0_12. I did this. It installed without difficulty, and then I was able to install Eclipse without difficulty.

This took hours of my time. I hope this proves useful.

Answer 2

OK, so I don't really know what the problem was, but I simply fixed it by navigating to here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and installing 8u74 instead of 8u73 which is what I was prompted to do when I would go to "download latest version" in Java. So changing the versions is what did it in the end. Eclipse launched fine, now. Thanks for everyone's help!

edit: Apr 2018- Now is 8u161 and 8u162 (Just need one, I used 8u162 and it worked.)

Answer 3

JRE is a Run-Time Environment for running Java stuffs on your machine. What Eclipse needs is JDK as a Development Kit.

Install the latest JDK (and not JRE) from http://www.oracle.com/technetwork/pt/java/javase/downloads/jdk8-downloads-2133151.html and you should be good on Mac!

Answer 4

Open up terminal and check what java version is currently set in your path variable.

You can do that by typing in your terminal

java -version // this will check your jre version. 
javac -version // this will check your compiler version

If this shows incorrect java version but you have installed java 1.8 then you have to set path variable to the newer version of java.

To do that do add the line:

export JAVA_HOME=/path/to/java/jdk1.x

to ~/.bash_profile (same as /Users/username/.bash_profile)

Then do this from the terminal to set the new variable

source ~/.bash_profile

Also what's your eclipse.ini set to ?

-Dosgi.requiredJavaVersion=1.7

EDIT:

Please open up terminal and type

 find / -name "java" // This should find all folder named java on your file system.

Also how did you install java in the first place ?
