When i import my Gradle Java project with Intellij Idea i get error
Intellij Idea
The project uses Gradle 2.12 which is incompatible with IDEA running on Java 10
In case if you didn't find switch boot JDK option in IDEA you can use "choose runtime" plugin.

if you want it in action, try Ctrl + shift + A then type choose runtime , in the dialog choose run time select the runtime you want.
