IntelliJ IDEA Gradle error - Could not determine java version from '9.0.1'.

I recently saw this error when I was trying to set up a Java project in IntelliJ IDEA. The error appeared every time I tried to 'run' my gradle file. The project built fine outside of IntelliJ IDEA for example by running Gradle directly. The error was:

FAILURE: Build failed with an exception.
* What went wrong:
Could not determine java version from '9.0.1'.

In order to solve this I pointed IntelliJ to my own gradle installation, instead of using the built in distribution. I did this by going to "File > Settings... > Build, Execution, Deployment > Gradle". Then I pointed IntelliJ to the location of Gradle on my PC. This of course requires you to have a Gradle installation on your machine.

java version from 9.0.1 gradle error in IntelliJ Idea

After this my project was built without any issues, if you have another (better?) solution to this, let me know in the comments!
