Migrate kotlinOptions to compilerOptions

[l2hyunwoo]

🎯 Goal

• Migrate kotlinOptions to compilerOptions function due to kotlinOptions is deprecated.

🛠 Implementation details

• I'd apply compilerOptions, but it is registered on KotlinAndroidProjectExtension, not BaseExtension. So I've to separate this code block to configureKotlinAndroid. So the result of migration is below.

// KotlinAndroid.kt

/*
* ETC
*/

// Newly added configuration function for `KotlinAndroidProjectExtension`
internal fun Project.configureKotlinAndroid(
  extension: KotlinAndroidProjectExtension,
) {
  extension.apply {
    compilerOptions {
      // Treat all Kotlin warnings as errors (disabled by default)
      allWarningsAsErrors.set(
        properties["warningsAsErrors"] as? Boolean ?: false
      )

      freeCompilerArgs.set(
        freeCompilerArgs.getOrElse(emptyList()) + listOf(
          "-Xcontext-receivers",
          "-Xopt-in=kotlin.RequiresOptIn",
          // Enable experimental coroutines APIs, including Flow
          "-Xopt-in=kotlinx.coroutines.ExperimentalCoroutinesApi",
          // Enable experimental compose APIs
          "-Xopt-in=androidx.compose.material3.ExperimentalMaterial3Api",
          "-Xopt-in=androidx.lifecycle.compose.ExperimentalLifecycleComposeApi",
          "-Xopt-in=androidx.compose.animation.ExperimentalSharedTransitionApi",
        )
      )

      // Set JVM target to 17
      jvmTarget.set(JvmTarget.JVM_17)
    }
  }
}

// AndroidApplicationConventionPlugin
class AndroidApplicationConventionPlugin : Plugin<Project> {
  override fun apply(target: Project) {
    with(target) {
      // ...etc

      // Newly Added
      extensions.getByType<KotlinAndroidProjectExtension>().apply {
        configureKotlinAndroid(this)
      }
    }
  }
}

// Also same as Library, Feature convention plugin
