How to install two different versions of IntelliJ IDEA (Ultimate Ed.) using Homebrew to custom locations/file names?

Background/Situation [Optional]

A user wants to install two different versions of IntelliJ IDEA (Ultimate Edition) using Homebrew on macOS. The latest version is usually installed at /Applications/IntelliJ IDEA.app. However, the user wants to install an earlier version at a different location, specifically /Applications/IntelliJ_IDEA_2024.3.2.1.app.

Question

How can one install two different versions of IntelliJ IDEA (Ultimate Edition) using Homebrew to custom locations/file names?

Answer

To install both versions of IntelliJ IDEA, you need to add the version number to the brew install command so each version will keep a different name: brew install @.

Here is an example of how to do this:

brew install intellij-idea@2024.3.2.1

This command will install IntelliJ IDEA version 2024.3.2.1.

Please note, an easy way to maintain multiple versions side by side is installing JetBrains Toolbox App to handle several versions of the same IDE.
