Pay attention to the “Project SDK” field, and make sure it shows a valid JDK version. It could be 1.7, 1.8, 1.9, …,  which are all fine, and your setup is now complete.

If it displays a message to the effect that no SDK is found, then you need to manually download and install JDK, please follow the instructions below for step 4.

Step 4. Download and install JDK

  • Visit (We will download JDK 8)
  • Under the table ” Java SE Development Kit 8u172″, select “Accept License Agreement”, and choose the correct file based on the operating system of your computer. For macbook, choose “Mac OS X x64”; For windows, choose “Windows x86” or “Windows x64”, depending on what OS you are running.
  • After downloading the correct JDK file, open it and follow the instructions to install. Write down which directory the JDK is installed into.
  • After the installation is completed, go back to IntelliJ. In the screen shot window above, click on the “New” button near the upper right corner. You will see a drop down select list as shown below:
