build.gradle

왜 apply false인가? 루트는 이런 플러그인이 있다고 선언만 하는 곳입니다.

실제 적용은 각 모듈 (app/build.gradle)에서 합니다.

// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    alias(libs.plugins.android.application) apply false
    alias(libs.plugins.compose.compiler) apply false
}
