Could not find com.android.tools.build:gradle: when executing ./gradlew generateCodegenArtifactsFromSchema

[silencer07]

Hi!

I am trying to follow this tutorial and the https://github.com/reactwg/react-native-new-architecture/blob/main/docs/turbo-modules.md but current I am stuck with this error:

A problem occurred configuring project ':rtn-splash-screen'.
Could not determine the dependencies of null.
Could not resolve all task dependencies for configuration ':rtn-splash-screen:classpath'.
> Could not find com.android.tools.build:gradle:.
> Required by:
> project :rtn-splash-screen

I have tried google and chatgpt and my efforts are in vain. This is the build.gradle of the turbo module

buildscript {
ext.safeExtGet = {prop, fallback ->
rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
}
repositories {
mavenCentral()
google()
}
dependencies {
classpath("com.android.tools.build:gradle")
classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${safeExtGet('kotlinVersion', '1.9.22')}")
}
}

apply plugin: 'com.android.library'
apply plugin: 'com.facebook.react'
apply plugin: "org.jetbrains.kotlin.android:${safeExtGet('kotlinVersion', '1.9.22')}"

android {
compileSdkVersion safeExtGet('compileSdkVersion', 34)
namespace "com.meccabrands.SplashScreen"
}

repositories {
mavenCentral()
google()
}

dependencies {
classpath("com.android.tools.build:gradle")
implementation 'com.facebook.react:react-native'
}

this is the android folder build.gradle

buildscript {
ext {
buildToolsVersion = "34.0.0"
minSdkVersion = 30
compileSdkVersion = 34
targetSdkVersion = 34
ndkVersion = "26.1.10909125"
kotlinVersion = "1.9.22"
}
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:$kotlinVersion")
}
}

subprojects {
afterEvaluate { project ->
if (project.hasProperty("android")) {
project.android.defaultConfig.minSdkVersion = 30
}
}
}

apply plugin: "com.facebook.react.rootproject"

can someone point me out what it is I am doing wrong? Thanks

Please use this template https://github.com/react-native-community/reproducer-react-native to create a reproducer of your failure, and I can then point you in the right direction 👍

Hi @cortinico ,

Thank you very much for extending a helping hand. As requested this is the reproducer repo:

https://github.com/silencer07/codgen-error-reproducer-react-native/tree/main/ReproducerApp

Note: I put the npx react-native info output on the said repo as well

Hi @cortinico,

Just wanna bump the discussion. Any insights how to fix this?

Thanks

Hey @silencer07 my apologies for the late reply but I missed this post.

The problem you have are in the Gradle file of your project:
https://github.com/silencer07/codgen-error-reproducer-react-native/blob/main/ReproducerApp/modules/RTNSplashScreen/android/build.gradle

If you're looking into publishing a library, please update the file with the following content:

buildscript {
  ext.safeExtGet = {prop, fallback ->
    rootProject.ext.has(prop) ? rootProject.ext.get(prop) : fallback
  }
  repositories {
    google()
    gradlePluginPortal()
  }
  dependencies {
    classpath("com.android.tools.build:gradle:7.3.1")
  }
}

apply plugin: 'com.android.library'
apply plugin: 'com.facebook.react'
apply plugin: 'org.jetbrains.kotlin.android'

android {
  compileSdkVersion safeExtGet('compileSdkVersion', 34)
  namespace "com.meccabrands.SplashScreen"
}

repositories {
  mavenCentral()
  google()
}

dependencies {
  implementation 'com.facebook.react:react-native'
}

I'm on JDK 17:

java -version
openjdk version "17.0.9" 2023-10-17 LTS
OpenJDK Runtime Environment Zulu17.46+19-CA (build 17.0.9+8-LTS)
OpenJDK 64-Bit Server VM Zulu17.46+19-CA (build 17.0.9+8-LTS, mixed mode, sharing)

Anyway Java version shouldn't make a difference here. There is something going on with your environment setup

[silencer07]

that's weird. I mean I am already building react native apps in my current macos laptop.

can you check if there is something amiss in the npx react-native info output here

https://github.com/silencer07/codgen-error-reproducer-react-native/tree/main/ReproducerApp#readme

[cortinico]

Info looks fine to me.
What I can suggest is to enable GitHub Actions on your reproducer. The CI is already configured and will build the app automatically, so you can tell if there is something going on with your setup

[silencer07]

Hi @cortinico,

I enabled github actions in my repo. It complained about lock file that will be updated. I run yarn install and for some reason this error went away.

What a relief! I think the error messsage should be improved (i.e. point out the problematic yarn lock file instead of the error in this thread)

Thank you very much. you are such a big help!
