"Package Does Not Exist" Build Failure for React Native build

Help/Discuss
1

I’m trying to build the Android side of my RN project. I’m not sure what causes this kind of “package <…> does not exist” build error. I want to confirm whether this issue is stemming from my use of Gradle, rather than React Native or the package.

terminal output of ./gradlew clean assemble

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/8.7/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Here is my build.gradle

buildscript {
    ext {
        buildToolsVersion = "34.0.0"
        minSdkVersion = 21
        compileSdkVersion = 34
        targetSdkVersion = 34

        google()

        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin")
    }
}
apply plugin: "com.facebook.react.rootproject"

here’s the settings.gradle

rootProject.name = 'myProject'
apply from: file("../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesSettingsGradle(settings)
include ':app'

If that is your whole build script, you do not declare any dependency so how do you expect the input to be resolved? It is there some RN magic that should apply?
