Android Gradle Plugin - what should I use in place of incubating abstractions, such as defaultConfig?

Question

I am new to Gradle, and I'm trying to port my android groovy build script to kts.

I have a working build, however Android studio is complaining (all over the place) about my syntax.

For example:

defaultConfig: 'defaultConfig(kotlin.jvm.functions.Function1<? super com.android.build.api.dsl.ApplicationDefaultConfig,kotlin.Unit>)' is marked unstable with @Incubating

'setApplicationId(java.lang.String)' is declared in unstable 'com.android.build.api.dsl.ApplicationBaseFlavor' marked with @Incubating

this goes on & on. When I look at the documentation, I can see that it is incubating, but it doesn't say what to replace with it, etc.

android {
    compileSdk = 31
    defaultConfig {
        applicationId = "myappId"
        minSdk = 21
        targetSdk = 31
        versionCode = 1
        versionName = "1.0"
        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    }

Should I just ignore these warnings? If so why are they warnings?

---

I just opened the project, on another machine and do not see the warning. The machine is running the exact same version of Android Studio:

• JVM
• Kotlin
• Gradle

When i click on something like the defaultConfig and navigate to the source, i see that it comes from exact same module. And it is marked as @Incubating.

I also checked the settings>Editor>Inspections and they both have the same settings.

This warning is nothing to do with Android Studio or compiler. It's from Gradle build system: link

The meaning of the warning is following:

...the feature is currently a work-in-progress and may change at any time.

For my pet-projects I do @Suppress("UnstableApiUsage") to dismiss it. But I would strongly recommend you not doing this for commercial/production projects. Better approach is to wait till the feature is stabilized by Gradle developers if you are using latest stable version. Or update to latest stable if possible.
