gradle - How to add Android Support Repository to Android Studio?

Question

I'm using Android Studio with an external Android SDK. I have installed the support library and the support repository. The support repository is in:

~/Development/Tools/android/sdk/extras/android/m2repository

When I add a dependency to the support library in the build.gradle file, like:

...

repositories {
    mavenCentral()
}

...

dependencies {
   compile "com.android.support:support-v4:18.0.+"
}

Android Studio cannot find the support libraries (cannot resolve symbol etc) and Gradle also cannot find the libraries:

Gradle: A problem occurred configuring project ':TestAndroidStudio'.
> Failed to notify project evaluation listener.
   > Could not resolve all dependencies for configuration ':TestAndroidStudio:_DebugCompile'.
      > Could not find any version that matches com.android.support:support-v4:18.0.+.

How do I specify in Android Studio and/or the build.gradle file the location of the Android support repository?

You are probably hit by this bug which prevents the Android Gradle Plugin from automatically adding the "Android Support Repository" to the list of Gradle repositories. The work-around, as mentioned in the bug report, is to explicitly add the m2repository directory as a local Maven directory in the top-level build.gradle file as follows:

allprojects {
    repositories {
        // Work around https://code.google.com/p/android/issues/detail?id=69270.
        def androidHome = System.getenv("ANDROID_HOME")
        maven {
            url "$androidHome/extras/android/m2repository/"
        }
    }
}
