Where is JAVA HOME on macOS Mojave 10 14 to Lion 10 7

Question

Java is an optional package on the latest versions of macOS     Yet once installed it appears like the JAVA HOME environment variable is not set properly

User · Answer

Got the same issue after I upgrade my Mac OS and following worked for me:

cmd>vi ~/.bash_profile
Add/update the line for JAVA_HOME: export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.7.0_15.jdk/Contents/Home"
cmd>source ~/.bash_profile or open a new terminal

I think the jdk version might differ, so just use the version which you have under /Library/Java/JavaVirtualMachines/

If you are in need to have multiple versions of JDK under Mac OS X  Yosemite   it might be helpful to add some scripting for automated switching between them    What you do is to edit your    bash profile and add the following   function setjdk       if      -ne 0    then    removeFromPath   System Library Frameworks JavaVM framework Home bin     if   -n    JAVA HOME x      then     removeFromPath  JAVA HOME    fi    export JAVA HOME   usr libexec java home -v        export PATH  JAVA HOME bin  PATH   fi     function removeFromPath       export PATH   echo  PATH   sed -E -e  s   1    -e  s  1          setjdk 1 7   What the script does is to first remove other JDK versions in the PATH so that they won   t interfere with our new JDK version  Then it makes some clever use of  usr libexec java home which is a command that lists installed JDK versions  The -v argument tells java home to return the path of the JDK with the supplied version  for example 1 7  We also update the PATH to point to the bin directory of the newly found JAVA HOME directory  At the end we can simply execute the function using  setjdk 1 7   which selects the latest installed JDK version of the 1 7 branch  To select a specific version you can simply execute  setjdk 1 7 0 51   instead  Run  usr libexec java home -V to get more details on how to choose versions   P S  Do not forget to  source    bash profile after you save it

This answer is related to Mountain Lion and not Lion  I needed to do this for the AWS Command Line Tools  According to the AWS docs  running which java returns  usr bin java   So  I set JAVA HOME  usr in my  bashrc   Apparently   usr bin java is a symbolic link to  System Library Frameworks JavaVM framework Versions Current Commands java which makes it all work   Update  As mentioned in the comment below  this JAVA HOME value is not an ideal solution when the JAVA HOME environment variable is to be used by things other than the AWS Command Line Tools  It works fine for the AWS Command Line Tools  though  as given in their docs

usr libexec java home is not a directory but an executable  It outputs the currently configured JAVA HOME and doesn t actually change it  That s what the Java Preferences app is for  which in my case seems broken and doesn t actually change the JVM correctly  It does list the 1 7 JVM but I can toggle untoggle  amp  drag and drop all I want there without actually changing the output of  usr libexec java home   Even after installing 1 7 0 u6 from Oracle on Lion and setting it as the default in the preferences  it still returned the apple 1 6 java home  The only fix that actually works for me is setting JAVA HOME manually   export JAVA HOME  Library Java JavaVirtualMachines jdk1 7 0 06 jdk Contents Home    At least this way when run from the command line it will use 1 7   usr libexec java home still insists on 1 6   Update  Understanding Java From Command Line on OSX has a better explanation on how this works    export JAVA HOME   usr libexec java home -v 1 7     is the way to do it  Note  updating this to 1 8 works just fine
