Eclipse (Android) and Mountain Lion – Problem with Java version

November 23, 2012

Eclipse stopped working after upgrade to Mountain Lion.  My initial guess was that it could be due to Java not being available.  I installed Oracle Java 7.

Even then, eclipse wasn’t starting up.   I tried changing eclipse.ini to set the VM.   No avail.

Finally,  I realised it could be due to the new security settings in Mountain Lion. To resolve this, go to System Preferences > Security & Privacy > General, and choose the check-box for “Anywhere.”  (You may need to unlock the settings before you can make this change)

Finally, Eclipse started working.

 

Other useful information I came across during my search:

[Thread from StackOverflow]

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 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.

[Edit eclipse.ini to specify a Java version]
