I’m trying to add support for the 2018.3 beta to my plugin. When I switch to compiling against 183.2407.10, I get tons of errors along the lines of:

Class 'kotlin.jvm.Throws' is compiled by a pre-release version of Kotlin and cannot be loaded by this version of the compiler

You can add

-Xskip-metadata-version-check

compiler argument in

build.gradle

(and in IDE) to suppress the error.
