Removing Java 8 JDK from Mac

Question

So I installed the beta of JDK 8 a while ago to look at some of the examples  I thought for sure by now  it s easy to change between versions    Doing some Play development with IntelliJ  For some reason  IntelliJ is compiling with 8 even though    I have the compiler set in Preferences to use 1 6 Supposedly it s using SBT through external build  but sbt from the command line works JAVA HOME is pointing to JDK 6    If I go to the Java Preferences page  it does show 8 installed  but there is no option to uninstall it and it doesn t see any of the other versions   When I do which java  it tells me  usr bin java and I do  usr bin java -version and it returns 1 6   Note  with a  little fiddling  you can use IntelliJ and JDK7  see here

Managing Java versions on Mac OSX is a nightmare   I recently switched over to using JDK 1 7  deleting JDK 6 from my MacBook entirely  I also had traces of JDK 5 - this laptop has been updated a few times    Here s what I did to move to JDK 7   1  download the latest from Oracle  http   www oracle com technetwork java javase downloads index html  and install it   2  Remove  using rm - if you ve got backups  you can revert if you make a mistake  all the JDK6 and JRE6 files   At this stage  you should see     ls  Library Java JavaVirtualMachines  jdk1 7 0 nn jdk    and nothing else   3  In the folder  Library Java Extensions   you ll need to remove all the old jar files  the ones that correspond to other releases of Java   If you don t  you ll get the infamous message about the wrong version of tools jar  see Builds failing after upgrading to Java7  Missing Tools jar and bad class versions    It is not enough to rename the jar files  because Java will open every jar in that folder - I moved mine into a sub-directory   It s safe to remove them once you know everything else works   I haven t found I need to set JAVA HOME for simple things   Note  I just tried running IntelliJ and it will not start unless you have Apple s JDK 6 installed  see http   youtrack jetbrains com issue IDEA-93710    Same is true for Eclipse  Netbeans works fine
