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 variabl

Answer 1

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 << EOF > ~/Library/LaunchAgents/setenv.JAVA_HOME.plist
  
  
    
    
      Label
      setenv.JAVA_HOME
      ProgramArguments
      
        /bin/launchctl
        setenv
        JAVA_HOME
        $(/usr/libexec/java_home)
      
      RunAtLoad
      
      ServiceIPC
      
    
  
  EOF
  

  Note that this also affects the Terminal process, so there is no need to put anything in your ~/.bash_profile.
