what's the difference of the kotlin version between gradle setting and IDE? I'm wondering of the difference of the kotlin version between gradle setting and ide. I can see the kotlin version of IDE(Tools -> Kotlin -> Configure Kotlin). And there is another kotlin version defined in build.gradle. I want to know the difference. I think that the version in buidl.gradle affects to real project and some dependencies. And the version in IDE affects when we wrtie the code. Is my guess is right?
