react-native: Android build fails in 0.71.0-rc.0 with "Could not find com.facebook.react:react-native:0.71.0-rc.0"

One last thing about libraries, when I add react-native libraries that have the line

implementation 'com.facebook.react:react-native:+'

in their build.gradle (like https://github.com/DataDog/dd-sdk-reactnative I’m working on), I get the following error when building for Android:

Could not determine the dependencies of task ':datadog_mobile-react-native:compileDebugAidl'.
> Could not resolve all task dependencies for configuration ':datadog_mobile-react-native:debugCompileClasspath'.
   > Could not find any matches for com.facebook.react:react-native:+ as no versions of com.facebook.react:react-native are available.
     Required by:
         project :datadog_mobile-react-native

Is it something due to the use of the maven-local or is it supposed to be fixed in a next 0.71 RC?

Tell me if you think this needs a new issue, I can open it 😃

Hey Guys,

i think im experiencing and error that is also related to this, but on RN 0.65.3 - so the latest patch for 0.65

Could not find any matches for com.facebook.react:hermes-engine:0.65.+ as no versions of com.facebook.react:hermes-engine are available.

It seems like there is no hermes version vailabel for this RN Version from my perspective? Would be super happy if someone could help out with that

Hi @cipolleschi @kelset, thanks for your quick help!

I think you need to update the links to maven-local.zip in both release and discussion - it links to https://github.com/facebook/react-native/blob/v0.71.0-rc.0 which shows a 404 to me. However there is a link at the bottom of the release (https://github.com/facebook/react-native/releases/download/v0.71.0-rc.0/maven-local.zip) which works 😉

After that I was able to start my app with the steps you provided 😃

Feel free to close this issue once the links are updated

Hi there! I am trying to update my RNative version to 0.70.6 and I am facing a similar issue to the one described in this thread. I have tried downgrading the version to 0.70.5 but I still have the same error:

Could not determine the dependencies of task ':app:processDebugResources'.
> Could not resolve all task dependencies for configuration ':app:debugRuntimeClasspath'.
   > Could not find any matches for com.facebook.react:react-android:+ as no versions of com.facebook.react:react-android are available.
     Searched in the following locations:
       - https://dl.google.com/dl/android/maven2/com/facebook/react/react-android/maven-metadata.xml
       - https://maven.google.com/com/facebook/react/react-android/maven-metadata.xml
       - https://www.jitpack.io/com/facebook/react/react-android/maven-metadata.xml

         project :app > project :react-native-mmkv

In my android/build.gradle I have the following:

allprojects {
  repositories {
    maven {
      // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
      url("$rootDir/../node_modules/react-native/android")
    }
    maven {
      // Android JSC is installed from npm
      url("$rootDir/../node_modules/jsc-android/dist")
    }
    mavenCentral {
      // We don't want to fetch react-native from Maven Central as there are
      // older versions over there.
      content {
        excludeGroup "com.facebook.react"
      }
    }

    google()
    maven { url "https://maven.google.com" }
    maven { url 'https://www.jitpack.io' }
  }
}

and under dependencies in android/app/build.gradle: implementation "com.facebook.react:react-native:+" I also tried updating the react-native-mmkv version to 2.6.1 but the error still arises… Does anyone know what the error could be here? Any help would be really appreciated!

The mmkv2.6+ version needs to rely on react-native71 or above, so it is still necessary to control the mmkv version to 2.5

A few hours after I posted a question here I found this useful thread (react-native-mmkv/issues/500) where I understood that the solution was downgrading mmkv library to version 2.5 because 2.6+ works for react native version 0.71+

Thanks anyway for your help fencer!

Thanks for flagging this @varemenos. As @kelset mentioned, we’re looking into those kind of issues right now. They’ll be fixed in RC3

@varemenos libraries will need to adapt to some of the changes coming with 0.71, we’re having direct conversations with some key maintainers to setup a migration story for everyone to use, we hope to have it ready ~RC3

I just upgraded to RC1 and tried to run an android app I’m developing locally. One of the dependencies it has is the community async storage (@react-native-async-storage/async-storage), does the library need to adapt to the new changes or was RC1 supposed to fix the issue for the libs too?

Could not determine the dependencies of task ':react-native-async-storage_async-storage:compileDebugAidl'.
> Could not resolve all task dependencies for configuration ':react-native-async-storage_async-storage:debugCompileClasspath'.

I assume this is related because it can’t match com.facebook.react:react-native:+ but I’m not 100% sure.

Just a heads up that we released 0.71.0-rc1 which should work fine, without having to specify any workaround or download any artifacts manually

yeah it’s expected because you’ll have to move away from that dep; read more of the state of libraries here: https://github.com/reactwg/react-native-releases/discussions/41

Once Nicola is back we’ll figure out the migration path for libraries

yeah so the reason is that we got SonarType to remove (less than 24hrs ago) the 0.71 artifacts from Maven Central, to avoid any further issues and bring back the situation as it was before for the ecosystem. We are writing up now how to test Android for 0.71 RC0 now that the maven artifacts for it don’t exist anymore on maven central, we’ll post those instructions both in the https://github.com/reactwg/react-native-releases/discussions/41 and in the release notes https://github.com/facebook/react-native/releases/tag/v0.71.0-rc.0
