Intellij Idea 14.1.4 Mac OS X Yosemite 10.10.3 and later.
From the IDE:
Import Project ->

Import project from exter
Just to add completness to the above selected answer, one can also go the 'Project Setting' windows (if not on the Welcome screen) in IntelliJ IDEA by clicking:
File > Project Structure (Ctrl + Alt + Shift + S)
And can define Project SDK there!
Make sure you have a jdk setup. To do this, create a new project and then go to file -> project structure. From there you can add a new jdk. Once that is setup, go back to your gradle project and you should have a jdk to select in the 'Gradle JVM' field.
For MacOS this worked for me without the need to hardcode a particular Java version:
launchctl setenv JAVA_HOME "$(jenv javahome)"
Try starting IntelliJ from terminal. You can find application file under: /Applications/IntelliJ\ IDEA\ 14.app/Contents/MacOS
If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:
launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"
As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.
For Windows Platform:
try Running the 64 Bit exe version of IntelliJ from a path similar to following.
note that it is available beside the default idea.exe
"C:\Program Files (x86)\JetBrains\IntelliJ IDEA 15.0\bin\idea64.exe"
