Vaadin 14 + JDK 14

General
1

I am using Kotlin with Gradle and tried Vaadin 14.1.27 with JDK 14. But in productionMode I get the following error

Starting a Gradle Daemon, 2 incompatible Daemons could not be reused, use --status for details
> Task :vaadinBuildFrontend FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':vaadinBuildFrontend'.
> Unsupported class file major version 58

This shows me that there’s an incompatibility with JDK 14 as of now. Or does somebody know of a solution to such problem?

Yes, but fortunatelly the problem has been fixed just recently, see

https://github.com/vaadin/flow/pull/8103

So it should come in some upcoming version soonish
