FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':react-native-webview:lintDebug'.
> Lint found errors in the project; aborting build.
  
  Fix the issues identified by lint, or create a baseline to see only new errors.
  To create a baseline, run `gradlew updateLintBaseline` after adding the following to the module's build.gradle file:
  ```
  android {
      lint {
          baseline = file("lint-baseline.xml")
      }
  }
  ```

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.5/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

이런 에러가 빌드에서 떴다.

이 에러는 android/build.gradle 파일에서 minSdkVersion 의 값을 바꾸면 되는 일이었다.

buildscript {
    ext {
        buildToolsVersion = "34.0.0"
        minSdkVersion = 21 // 이 부분은 23으로 변경
        compileSdkVersion = 34
        targetSdkVersion = 34
        ndkVersion = "25.1.8937393"
        kotlinVersion = "1.8.0"
    }
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath("com.android.tools.build:gradle")
        classpath("com.facebook.react:react-native-gradle-plugin")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin")
    }
} 
apply plugin: "com.facebook.react.rootproject"

그럼 빌드가 성공한다!
