I'm having trouble setting up

kotlinOptions

in a multiplatform lib project. As per the docs I added this to the

kotlin

section in the lib's `build.gradle`:

targets.all {
        compilations.all {
            kotlinOptions {
                suppressWarnings = true // just to see if it's applied
            }
        }
    }

But it does not work (warnings are still displayed in the IDE). Anybody else having issues with these compiler options? I'm using IntelliJ Idea 2019.1.2 and gradle 5.1.1

You're doing everything correctly. The reason warnings are not being disabled in IDE is because of this bug: https://youtrack.jetbrains.com/issue/KT-23101. The warnings should be properly disabled in the Gradle build.

Oooh, ok. Thanks for the update!
