Question or issue on macOS:
I want to use the JRE 1.7 that I downloaded from Oracle website.
Installing Java 8 and Eclipse on Mac OS X. This page tells you how to download and install Java 8 and Eclipse on Mac OS X, and how to configure Eclipse. Installing Java 8. Go to the Oracle website. You'll see something like this. Oracle strongly suggests to now use the term JDK to refer to the Java SE Development Kit. The Java EE SDK is available with or without the JDK, by which they specifically mean the Java SE 7 JDK. Follow below steps to install JDK on Mac OS High Sierra 10: Open your browser; go to Oracle JDK Download URL; Click on Download Image. Accept the licence. Eclipse download free for mac os its used by Via a Java plugin system, it enables programmers in different languages for example Java, C, C, Perl, Python, PHP to collaborate using the a minimum of difficulty.Eclipse designed entirely in Java but goes far beyond Java.It doesn’t matter what language the consumer chooses, the editor provides free, universal toolset. Appear as a link below 'Download eclipse-SDK-3.7.1-macosx-cocoa.tar.gz from:' If so, click that link to start downloading. Otherwise, you can use any of the mirror sites listed on the page.
So I correctly install the .pkg file, and when I try /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version in the terminal I get this :
But in Eclipse I can’t use anything else than JRE 1.6. When I go in Properties > Java Build Path > Add Library > JRE System Library, I can’t find the 1.7 (there is only option for it : JavaSE-1.7 (unbound) with this issue :
What should I do ? Thanks
How to solve this problem?
Solution no. 1:
The download from java.com which installs in /Library/Internet Plug-Ins is only the JRE, for development you probably want to download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_<something>.jdk/Contents/Home which you can then add to Eclipse via Preferences -> Java -> Installed JREs.
Solution no. 2:
Try editing your eclipse.ini file and add the following at the top
Of course the path may be slightly different, looks like I have an older version…
I’m not sure if it will add itself automatically. If not go into
Preferences –> Java –> Installed JREs
Click Add and follow the instructions there to add it
Solution no. 3:
You need to tell Eclipse which JDK/JRE’s you have installed and where they are located.
This is somewhat burried in the Eclipse preferences: In the Window-Menu select “Preferences”. In the Preferences Tree, open the Node “Java” and select “Installed JRE’s”. Then click on the “Add”-Button in the Panel and select “Standard VM”, “Next” and for “JRE Home” click on the “Directory”-Button and select the top level folder of the JDK you want to add.
Its easier than the description may make it look.
Hope this helps!
