In IntelliJ you can set the target Java version like this:

Unfortunately I don't see a place where I can do the same for Kotlin. This makes it not possible for me to use Quasar-Kotlin. I want to switch to M14 even though I have 1.0 beta installed. How can I change back?

After changing the build.gradle file back to M14 I am greeted with compilation errors in my project.

Go to Intellij Preferences -> Build, Execution, Deployment -> Kotlin Compiler. Update Language version and Api version to the one you wish.

(You can also use cmd + shift + A and type Kotlin Compiler to get to this preference)
