kotlinlang

I'm trying to upgrade a maven project to kotlin 1.4, but it depends on a lib using kotlin 1.3 and I'm getting complaints about `Runtime JAR files in the classpath should have the same version`.  Is it possible to depend on a 1.3 lib in a 1.4 project?  Should I be setting the kotlin-stdlib dependencies in the 1.3 project to `compile` scope or something?

My main problem here ended up being not 'overriding' the dependency runtimes (lib had `kotlin-stdlib-jdk8` and my project just had `kotlin-stdlib`), but I'm still curious if there's anything I should to do ensure compatibility here.
