Question

I have installed the JDK on Mac nbsp OS nbsp X nbsp v10 8  Mountain Lion   When I upgraded it to Mac nbsp OS nbsp X nbsp v10 9  Mavericks  and ran java -version in the terminal  it showed      No Java runtime present  requesting install    Then I manually installed the JDK  1 7  on my Mac  It seems that the installation worked fine  When the installation was done  I opened the terminal and typed java -version as well  It also showed the same error      No Java runtime present  requesting install    How can I solve this problem

The new Mavericks  10 9  showed me the  Requesting install   but nothing happened    The solution was to manually download and install the official Java package for OS nbsp X  which is in Java for OS X 2013-005   Update  As mentioned in the comments below  there is a newer version of this same package   Java for OS X 2014-001  Java for OS X 2014-001  Correcting dead line above      Java for OS X 2014-001 includes installation improvements  and supersedes all previous versions of Java for OS X  This package installs the same version of Java 6 included in Java for OS X 2013-005

The OP implied that Java 7 was the need  And Java 6 is in fact no longer being  supported  so 7 is the version you should be installing at this point unless you have legacy app concerns   You can get it here  http   java com en download mac download jsp locale en

This error happens because the plist file of IntelliJ IDEA requires Java version 1 6   To solve this problem  replace the 1 6  with 1 8     lt key gt JVMOptions lt  key gt   lt dict gt       lt key gt ClassPath lt  key gt                  lt key gt JVMVersion lt  key gt       lt string gt 1 8  lt  string gt        lt key gt MainClass lt  key gt       lt string gt com intellij idea Main lt  string gt       lt key gt Properties lt  key gt   lt dict gt

There isn t any need to install the JDK  which is the developer kit  just the JRE which is the runtime environment

If you only want to install the latest official JRE from Oracle  you can get it there  install it  and export the new JAVA HOME in the terminal    Open your Terminal java -version gives you an error and a popup Get the JRE dmg on http   www oracle com technetwork java javase downloads index html Install it In your terminal  type  export JAVA HOME   Library Internet Plug-Ins JavaAppletPlugin plugin Contents Home  java -version now gives you java version  1 7 0 45    That s the cleanest way I found to install the latest JRE   You can add the export JAVA HOME line in your  bashrc to have java permanently in your Terminal   echo export JAVA HOME    Library Internet Plug-Ins JavaAppletPlugin plugin Contents Home    gt  gt     bashrc

I downloaded and installed the JDK 1 7 from Oracle  In the console   in Terminal Java 7 works fine    When I start a Java program  like Eclipse  via the GUI  I get      To open  Eclipse app  you need a Java SE 6 runtime  Would you like to   install one now    Because I did not want to install old Java version  I used the following workaround   sudo ln -nsf  Library Java JavaVirtualMachines jdk1 7 0 45 jdk Contents  System Library Frameworks JavaVM framework Versions CurrentJDK  Credits to monkehWorks

The right place to download the JDK for Java 7 is Java SE Downloads   All the other links provided above  as far as I can tell  either provide the JRE or Java 6 downloads  incidentally  if you want to run Eclipse or other IDEs  like IntelliJ IDEA  you will need the JDK  not the JRE    Regarding IntelliJ IDEA - that will still ask you to install Java 6 as it apparently needs an older class loader or something  just follow the instructions when the dialog pop-up appears and it will install the JDK 6 in the right place   Afterwards  you will need to do the sudo ln -snf mentioned in the answer above   sudo ln -nsf  Library Java JavaVirtualMachines jdk1 7 0 45 jdk Contents        System Library Frameworks JavaVM framework Versions CurrentJDK    copied here as it was mentioned that  above  may eventually not make sense as answers are re-sorted    I also set my JAVA HOME to point to where jdk 1 7 0 xx jdk was installed   export JAVA HOME   Library Java JavaVirtualMachines jdk1 7 0 45 jdk Contents Home    Then add that to your PATH   export PATH  JAVA HOME bin  PATH   The alternative is to fuzz around with Apple s insane maze of hyperlinks  but honestly life is too short to bother
