Eclipse on Mac 10.8 - Installed 1.7.0 JRE / JDK, but Eclipse won't launch

Question

• Installed Java SE 1.7.0u10 from Oracle w/ their installer package

• Downloaded and unpacked Eclipse Juno (4.2.1)

• Double click Eclipse

Answer 1

1. Install latest JDK from Sun, it installs into /Library/Java/JavaVirtualMachines/, e.g. /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk

2. sudo mkdir /System/Library/Java/JavaVirtualMachines

3. sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/ /System/Library/Java/JavaVirtualMachines/1.6.0.jdk

========= this trick used to work on Mountain Lion, but not on Maverick 10.9 somehow ============

Tried this again on Maverick, it does not work anymore. I also tried to change eclipse app plist and eclipse.ini (by adding -vm or ), does not work either.

Some people suggested that this is caused by Eclipse binary prepared using Apple 1.6 appbundler instead of Oracle java7 appbundler: Application is using Java 6 from Apple instead of Java 7 from Oracle on Mac OS X?

For now, please just type the eclipse from command line, which works fine with JAVA_HOME set to Java 7 (/usr/libexec/java_home command will tell you)
