Setting up and using environment variables in IntelliJ Idea
Intellij IdeaEnvironment VariablesIntellij Idea Problem Overview
I set up an environment variable (Under IDE Settings -> Path Variables)
APP_HOME = /path/to/app_home
One of my tests is failing however with
System.out.println("APP HOME: " + APP_HOME);
With
APP HOME: null/
It does not look like that env variable is being read. What am i missing?

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 the above answer + restarting the IDE didn't do, try restarting "Jetbrains Toolbox" if you use it, this did it for me
Solution 3 - Intellij Idea
It is possible to reference an intellij 'Path Variable' in an intellij 'Run Configuration'.
In 'Path Variables' create a variable for example ANALYTICS_VERSION.
In a 'Run Configuration' under 'Environment Variables' add for example the following:
ANALYTICS_LOAD_LOCATION=$MAVEN_REPOSITORY$\com\my\company\analytics\$ANALYTICS_VERSION$\bin
To answer the original question you would need to add an APP_HOME environment variable to your run configuration which references the path variable:
APP_HOME=$APP_HOME$

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.
