Answer 1

It seems it is a problem with different Ktlin verion as explained in Building Kotlin projects with Gradle sometimes fails with NoClassDefFoundError

Answer 2

Yes, as many before have said, the problem is probably that you have a kotlin version mis-match. But how do you know what version of kotlin is installed?

To find out your version of kotlin: Settings -> Language & Frameworks -> Kotlin

Make sure that you change your kotlin version (in both build.gradle files!) to this exact number. In my case (above) it's 1.4.10

Good luck!

Answer 3

update your Version in your gradle.properties file. eg) kotlinVersion=1.3.72

Answer 4

Simplest solution:

Go to file -> project structure (ctrl+shift+alt+s) -> suggestions -> accept all the suggestions.

To answer the OP's quetion, you just need to accept the one with the kotlin version
