If you started IntelliJ through "JetBrains Toolbox", then in order to reload the environment variables you need to close them both (IntelliJ & Toolbox), start the toolbox, and then start IntelliJ via the toolbox.

Refreshing environment variables – IDEs Support (IntelliJ Platform) | JetBrains
April 25, 2012 - Normally, environment variables should be reloaded after the IDE restart. Do you have Toolbox application installed? Try to restart not only IntelliJ process but Toolbox application as well · Hi Egor Klepikov I don't have the Toolbox application installed. And I'm facing that issue: env. variables are not updated after IDEA restart/validate cache

Not possible. Once you start a process in Windows or in Unix, you can't read updated environment variables from outside. You can only change environment variables inside your process.
This IntelliJ plugin might not be completely restarting the app, but is i.e. using a different class loader instead.

May 6, 2025Probably a stupid question about JDK version in IntelliJ
There must have been a step missing in the course about downloading and going through the install steps for Java. That’s why the shell can’t find it, it’s not in the cmd path as others mentioned. But you know know the place where IntelliJ helpfully installed one for you. So use that long path, add \java -version to the end of it and execute that long command. You’ll have a command that looks like c:\……\bin\java -version More on reddit.com

July 31, 2021IntelliJ Idea installation (for java android programming) what does this checkbox means (add launchers dir to the path)
Any programs in a directory in your system %PATH% variable are accessible in the cmd console from any location. If you check that then you can open a command line console in any directory and enter the command "idea" to open IntelliJ IDEA. If you don't check it then to launch idea from the cmd console you would first have to navigate to the install directory. You can always add the directory to your PATH later if you don't do it now but you want to in the future (just search "Environment Variables" in Windows and edit PATH and add the intelliJ IDEA install directory to the list of directories there). I've never opened intelliJ this way, I just use a shortcut in my taskbar (or search in the windows search menu). My guess is you wouldn't need it, if you used the command line a lot you should be familiar with the PATH variable. It's just a convenience option for command line users so that they don't have to manually add the program to PATH. More on reddit.com

Environment variables not updated after IntelliJ update – IDEs Support (IntelliJ Platform) | JetBrains
January 30, 2019 - The path of the IntelliJ installation directory contains its version (i.e. C:\Users\<user>\AppData\Local\JetBrains\Toolbox\apps\IDEA-U\ch-0\183.5153.38\). Each time IntelliJ is updated to a new version, this path changes. However, the environment variable IDEA_JDK_64, which points to this path, is left unchanged.

Path Variables dialog has nothing to do with the environment variables.
Environment variables can be specified in your OS or customized in the Run configuration:
If you want to specify default environment variables for every new unit test configuration (as per this answer):

I could not get environment variables to work when IntelliJ Build and run property was using Gradle. I am not sure what the root cause is, but switching to IntelliJ IDEA solved the problem. Go to Preferences -> Build, Execution, Deployment -> Build Tools -> Gradle. Then change Build and run using: to IntelliJ IDEA.

r/IntelliJIDEA on Reddit: Environment Variable Manager Plugin
May 6, 2025 -
Hey everyone!
👋 I recently built a plugin called Environment Variable Manager to help manage environment variable sets directly within IntelliJ IDEA. I made it because I was constantly switching between different configs and got tired of copy-pasting env vars and manually updating into run configurations.
The plugin lets you:
-
Create/edit/clone multiple env var sets
-
Import/export from .env files
-
Easily switch the active set and inject it into your run configs with one click
-
Keep everything persistent across IDE restarts
It’s open source and still pretty new—if you want to give it a try or share feedback, I’d love that. Contributions are also very welcome!
