Gradle Could not resolve all dependencies

Question

I am trying one simple thing: To import some of Google's libraries in order to use the Gmail API. I am aware that some of these jars do not exist on mavenCentral. I therefore updated my Google Repositories from the sdk manager and instructed gradle to look in the sdk. I also removed the version numbers in the end of the dependencies and replaced them with a + which did not resolve my problem and therefore fall back to the original build.gradle file.

My build.gradle file looks like this:

buildscript {
    repositories {
        mavenCentral()


        def androidHome = System.getenv("ANDROID_HOME")
        maven {
            url "$androidHome/extras/android/m2repository/"
        }
    }


    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.0'
    }
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.hellobusiness.hotels"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                'proguard-rules.pro'
        }
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.google.api-client:google-api-client:1.20.0'
    compile 'com.google.api-client:google-api-client-android:1.20.0'
    compile 'com.google.api-client:google-api-client-gson:1.20.0'
    compile 'com.google.apis:google-api-services-gmail:v1-rev29-1.20.0'
}

The error I get:

FAILURE: Build failed with an exception.

I use eclipse with adt plugin and I use gradle from the command line

Answer 1

You have to add this part in your build.gradle

repositories {
    mavenCentral()
}

These libraries are in Central Maven:

com.google.api-client:google-api-client:1.20.0.
com.google.api-client:google-api-client-android:1.20.0
com.google.api-client:google-api-client-gson:1.20.0

About this library, I don't know where is.

com.google.apis:google-api-services-gmail:v1-rev29-1.20.0

Also I suggest you using the version of:

• Android Studio 1.2.x
• classpath 'com.android.tools.build:gradle:1.2.3'
• gradle 2.4
