react-native: android : Failed to resolve

Moving the jcenter repository to the last position fixed the issue for me: in android/build.gradle

before:

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        google()
    }
}

And after the fix:

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        google()
        jcenter()
    }
}

Switching the order of jcenter() and google() didn’t work for me…

@filipef101 approach that works for me:

My root build.gradle file:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "27.0.3"
        minSdkVersion = 16
        compileSdkVersion = 27
        targetSdkVersion = 26
        supportLibVersion = "27.1.1"
    }
    repositories {
        maven { url "https://maven.google.com" }
        jcenter()
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        maven {
            url "https://maven.fabric.io/public"
        }
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:3.2.1'
        classpath 'de.undercouch:gradle-download-task:3.1.2'
    }
}

allprojects {
    repositories {
        mavenLocal()
        maven { url "https://maven.google.com" }
        jcenter()
        google()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}


task wrapper(type: Wrapper) {
    gradleVersion = '4.4'
    distributionUrl = distributionUrl.replace("bin", "all")
}

Looks like someone (again?) mistakenly uploaded an incomplete Android support package to jcenter. https://jcenter.bintray.com/com/android/support/support-vector-drawable/maven-metadata.xml there was an update on 23.Oct and only pom desc file but no aar package https://jcenter.bintray.com/com/android/support/support-vector-drawable/27.1.1/

I have the same problem at this morning.

@kmend Don’t close the issue. And make the title more obvious so that some core members could see this soon.

@YuriyNskiy - It may be one of your react-native libraries in your package.json that are failing when building the react-native application. I kept getting this error: A problem occurred configuring project ‘:react-native-camera’.

> Could not resolve all files for configuration ':react-native-camera:classpath'.
   > Could not find intellij-core.jar (com.android.tools.external.com-intellij:intellij-core:26.0.1).
     Searched in the following locations:
        https://jcenter.bintray.com/com/android/tools/external/com-intellij/intellij-core/26.0.1/intellij-core-26.0.1.jar

React-native-camera updated their build.gradle file and all I pulled the latest changes and voila… My react-native-camera module. Check to see if any of your external libraries have been updated. If you do get an error with your libraries you could update the library’s build.gradle file in node_modules/{libraryFolder}/android/buidle.gradle (not a solution btw, just a process of elimination to see if the error is coming form the libraries)

Thank you @nvelozsavino , moving jcenter() to last position fixed the issue.
