Intellij JAVA HOME variable

Question

I started using Gradle and Intellij but I am having problems to configure Gradle s JVM  When I start a new Gradle project I am not allowed to define JVM as my JAVA HOME variable  The following screenshots show what is happening     As you can see Intellij says that my JAVA HOME variable is not defined  however if I type echo  JAVA HOME I can get my Java directory  in my case   Library Java JavaVirtualMachines jdk1 8 0 45 jdk Contents Home  My    bash profile is configured as follow  export JAVA HOME    usr libexec java home   Someone can figure what is happening   Thank you

If you d like to have your JAVA HOME recognised by intellij  you can do one of these    Start your intellij from terminal  Applications IntelliJ IDEA 14 app Contents MacOS  this will pick your bash env variables  Add login env variable by executing  launchctl setenv JAVA HOME   Library Java JavaVirtualMachines jdk1 8 0 60 jdk Contents Home    To directly answer your question  you can add launchctl line in your    bash profile  As others have answered you can ignore JAVA HOME by setting up SDK in project structure

In my case I needed a lower JRE  so I had to tell IntelliJ to use a different one in  Platform Settings    Platform Settings   SDKs     8984      Click the   button to add a new SDK  or rename and load an existing one  Choose the  Contents Home directory from the appropriate SDK  i e   Library Java JavaVirtualMachines jdk1 8 0 45 jdk Contents Home

So far  nobody has answered the actual question      Someone can figure what is happening     The problem here is that while the value of your  JAVA HOME is correct  you defined it in the wrong place    When you open a terminal and launch a Bash session  it will read the    bash profile file  Thus  when you enter echo  JAVA HOME  it will return the value that has been set there  When you launch IntelliJ directly  it will not read    bash profile     why should it  So to IntelliJ  this variable is not set    There are two possible solutions to this    Launch IntelliJ from a Bash session  open a terminal and run   Applications IntelliJ IDEA app Contents MacOS idea   The idea process will inherit any environment variables of Bash that have been exported   Since you did export JAVA HOME      it works    or  the sophisticated way  Set global environment variables that apply to all programs  not only Bash sessions  This is more complicated than you might think  and is explained here and here  for example  What you should do is run   bin launchctl setenv JAVA HOME    usr libexec java home    However  this gets reset after a reboot  To make sure this gets run on every boot  execute  cat  lt  lt  EOF  gt    Library LaunchAgents setenv JAVA HOME plist  lt  xml version  1 0  encoding  UTF-8   gt   lt  DOCTYPE plist PUBLIC  -  Apple  DTD PLIST 1 0  EN       http   www apple com DTDs PropertyList-1 0 dtd  gt     lt plist version  1 0  gt     lt dict gt       lt key gt Label lt  key gt       lt string gt setenv JAVA HOME lt  string gt       lt key gt ProgramArguments lt  key gt       lt array gt         lt string gt  bin launchctl lt  string gt         lt string gt setenv lt  string gt         lt string gt JAVA HOME lt  string gt         lt string gt    usr libexec java home  lt  string gt       lt  array gt       lt key gt RunAtLoad lt  key gt       lt true  gt       lt key gt ServiceIPC lt  key gt       lt false  gt     lt  dict gt   lt  plist gt  EOF   Note that this also affects the Terminal process  so there is no need to put anything in your    bash profile

Bit counter-intuitive  but you must first setup a SDK for Java projects  On the bottom right of the IntelliJ welcome screen  select  Configure   Project Defaults   Project Structure    The Project tab on the left will show that you have no SDK selected   Therefore  you must click the  New     button on the right hand side of the dropdown and point it to your JDK  After that  you can go back to the import screen and it should be populated with your JAVA HOME variable  providing you have this set

The problem is your  Project SDK  is none  Add a  Project SDK  by clicking  New      and choose the path of JDK  And then it should be OK
