Eclipse 4.2, Mac OS X 10.8 (ML), and Java 6

I'm trying to run Eclipse 4.2 (latest from website: eclipse-SDK-4.2-macosx-cocoa-x86_64) on Mac OS X 10.8 (Mountain Lion).

I have Java 7 installed, but I keep getting prompted to install Java 6. When I choose to forgo the install by clicking "Not Now", Eclipse exits.

$ java -version
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

$ whereis java
/usr/bin/java

Any ideas on how to get Eclipse to work with the latest version of Java? README is lacking any useful information (and even claims Eclipse was tested with Java 7 on some platforms).

UPDATE: Running sudo /Applications/.Eclipse/Eclipse.app/Contents/MacOS/eclipse works fine. After running under sudo and then switching back to lowly me with /Applications/.Eclipse/Eclipse.app/Contents/MacOS/eclipse results in a lock file error (permission denied).

It appears I have two problems:

UPDATE: It appears to be more junk from Cupertino:

Here's the text that Apple wants to hide from the world:

I purchased a new Mac Book Pro. I immediately upgraded to Mountain Lion. I installed Java 7 from Sun [Oracle]:

$ java -version java version "1.7.0_05" Java(TM) SE Runtime Environment (build 1.7.0_05-b06) Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

$ whereis java /usr/bin/java

$ /usr/libexec/java_home /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

When I attempt to run the Java Preferences (in /Applications/Utilities) and Eclipse, I get prompted to install Java (see attachment).

This outdated article was no help (adding environment.plist): https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/EnvironmentVars.html. I thought the problem might be $JAVA_HOME was not set, but I was wrong.

I think I got more useful information from Stack Overflow rather than the vendor (Apple), but its still not solved. https://apple.stackexchange.com/questions/58203/mountain-lion-with-java-7-only and https://apple.stackexchange.com/questions/57986/multiple-java-versions-support-on-os-x-and-java-home-location.

Please fix this. I spends thousands on Apple hardware and hundreds on Apple software, and this sort of thing is not acceptable. I have personally wasted hours on this issue, as have others. How can the Apple QA department miss another gapping hole?

Can you imagine that? You have to install a JDK 1.6 to get eclipse ran properly, even if you already have jdk 1.7 installed, and set the JAVA_HOME properly.

To resolve your issue, you just need to download the jdk1.6 from http://support.apple.com/kb/DL1572?viewlocale=en_US, and install it, later you will be able to run eclipse, and you can set the JAVA_HOME to JDK1.7, and you will be able to find the JDK1.7 from eclipse "Preferences".

Installing this update from apple fixed it for me: http://support.apple.com/kb/DL1572

Note that's the update that's trying to install automatically.

I'm rather embarrassed but one of my students helped me solve this issue.

If you have Java 7 installed then you should be using the 64 bit version of Eclipse. I had downloaded the 32 bit version and it was asking me to install Java 6 when I had version 7 installed. Downloaded the 64bit version and it works like a dream. I run Mac os 10.8

The MAC OS offers the Java Preferences tool under Applications.

If you don't have this tool you can edit the eclipse.ini and manually specify the JVM that you want to use.

Of course remember that Java 7 is the only Java official release for MAC and is probably not the best for developing applications. I would go for the 1.6 release but you are forced with this one due to OS restrictions if you want to stick with the standard.

From here.

JDK 7 will be installed under /Library/Java/JavaVirtualMachines/1.7.0.jdk, JDK 6 under /System/Library/Java/JavaVirtualMachines.

To trick OS X to accept Java 7 instead of proposing to install Java 6 a simple symlink is enough:

    sudo mkdir /System/Library/Java/JavaVirtualMachines
    sudo su ln -s /Library/Java/JavaVirtualMachines/1.7.0.jdk /System/Library/Java/JavaVirtualMachines/1.6.0.jdk

Most Java Programms will run with this little hack without the need to install Java 6.

Note that the OP in the above question specifically talks about Eclipse not working with Java 7.

Also this might be worthwhile read.
