[java] Eclipse not recognizing JVM 1.8

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!

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!

Here are steps:

• download 1.8 JDK from this site
• install it
• copy the jre folder & paste it in "C:\Program Files (x86)\EclipseNeon\"
• rename the folder to "jre"
• start the eclipse again

It should work.

For some weird reason "Java SE Development Kit 8u151" gives this trouble. Just install, "Java SE Development Kit 8u152" from the following link-

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

It should work then.

Echoing the answer, above, a full install of the JDK (8u121 at this writing) from here - http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html - did the trick. Updating via the Mac OS Control Panel did not update the profile variable. Installing via the full installer, did. Then Eclipse was happy.

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 ?

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.
