After setting up the Java 8 SDK, you need to install IntelliJ IDEA. This is the Java development environment that HappyBrackets integrates with via its plugin.
Download and install IntelliJ V 2018.3 IntelliJ IDEA. There is currently an issue with Versions 2019 and later with respect to the version of Java being used. When you get to the download page, select the Free Community version

Alternatively, you can make desktop file so you can just run from the mouse. Point the target in your desktop file to the idea.sh in the IntelliJ bin folder
The IntelliJ package needs to be configured before you can develop on it. This involves two steps. First, you need to configure IntelliJ to work with the Java Development Kit. Second, you need to install the HappyBrackets Plugin.
We need to configure Intellij so it will know where to load the Java 8 SDK.
Start IntelliJ and close any projects if you had opened or created one.
From the Configure dropdown, select Project Defaults and then Project Structure.
See if the JDK has been automatically detected by Intellij. Click SDK's under the Platform Settings section and check that you have 1.8 installed, as shown in the image below. If it is not, we will need to configure this.
If 1.8 was not displayed, click on the + (Add New SDK) button.
Select JDK option
Navigate to the path where the SDK is installed.
on a windows machine, it may look like this.
on a Linux machine, point it to where you downloaded the JDK
After selecting the folder, click the Apply button, followed by OK.
