Unresolved reference for synthetic view when layout is in library module

Question

using Kotlin 1.20.20 (not that it matters, older versions behaves the same)

When layout is in separate library module Android Studio has no problem finding and refer

Answer 1

I solved my issue with copy both androidExtension and buildscript from project build.gradle to module that uses the library.

buildscript {

    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:$gradle_version"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

androidExtensions {
    experimental = true
}

Note: I use the following version of kotlin and gradle:

buildscript {
    ext.kotlin_version = '1.3.0'
    ext.gradle_version = '3.0.1'
