Breaks when upgrading Gradle to 4.x

I've been using kotlinconf-app as a reference for how to get a Kotlin React application to work with a Kotlin Multiplatform dependency. Super cool stuff!

I noticed that the Gradle wrapper in this project is set to v3.3 and the setup here only works with v3.x. When I try to upgrade to a more recent v4.x Gradle version I get these Webpack errors:

I'd like to get this working with Gradle v4.x because I'm trying to integrate this approach into an existing Gradle multi-project application that has a Spring Boot application. The org.springframework.boot Gradle plugin requires Gradle 4.0 or later (spring-projects/spring-boot#9516).

Any ideas of how to get a Gradle setup like the one here in kotlinconf-app to play nice with Gradle v4.x or even just what's going wrong when I try it?

@lnhrdt Thank you for raising this. Gradle plugin has been updated to 4.9-rc-1 with #14.
