Gradle Build Android Project "Could not resolve all dependencies" error

Question

I'm trying to build my first project with Gradle and I think my gradle files and settings are correct.

I'm using only one module and Support V4 + AppCompatBar libraries.

Project - build.gradle

allprojects {     repositories {         mavenCentral()     } } 

Project - settings.gradle

include ':AssignmentTempos21' 

Main module - build.gradle

buildscript {     repositories {         mavenCentral()     }      dependencies {         classpath 'com.android.tools.build:gradle:0.5.+'     } }  apply plugin: 'android'  repositories {     mavenCentral() }  android {     compileSdkVersion 17     buildToolsVersion "17.0.0"      defaultConfig {         minSdkVersion 8         targetSdkVersion 17     } }  dependencies {     compile "com.android.support:support-v4:18.0.+"     compile "com.android.support:appcompat-v7:18.0.+" } 

Console output with -i flag:

Answer 1

As Peter says, they won't be in Maven Central

from the Android SDK Manager download the 'Android Support Repository' and a Maven repo of the support libraries will be downloaded to your Android SDK directory (see 'extras' folder)

to deploy the libraries to your local .m2 repository you can use maven-android-sdk-deployer

2017 edit:

you can now reference the Google online M2 repo

repositories { google() jcenter() }
