Hello, I'm using Kotlin 1.2.71-release-IJ2018.2-1, IntellJ 2018.2.4 #IC-182.4505.22, with a Javascript project without Gradle, and I always get an error with the serialization plugin for IntelliJ when trying to compile my project. The direct link to the Latest release (1.2.70) in the github readme.md "doesn't work" and I tried installing different versions, 6.2, 6.1... but all of them are failing.

Thanks for report, I’ve fixed the broken link. Can you try it now?

Thanks. I think that version was the first I tried. It doesn't work for me. I forgot to mention that my project is a kotlin-javascript without gradle.

Stacktrace looks like you probably use an outdated version of runtime library, is it 0.6.2 ?

I thought that the runtime library was only used when running the code, and as I had to update it manually, I still had an older version. Everything is working now. Thanks!
