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()
}

Answer 2

compileSdkVersion 17
targetSdkVersion 17

change the compile version from 18 to 17

compile "com.android.support:support-v4:17.0.+"
compile "com.android.support:appcompat-v7:17.0.+"

Answer 3

Add this to your gradle:

allprojects {
    buildscript {
        repositories {
            maven {
                url "https://dl.bintray.com/android/android-tools"
            }
        }
    }
...
}

Answer 4

I had this message in Android Studio 2.1.1 in the Gradle Build tab. I installed a lot of files from the SDK Manager but it did not help.

I needed to click the next tab "Gradle Sync". There was a link "Install Repository and sync project" which installed the "Android Support Repository".

Answer 5

Try to turn off your firewall, it works for me. It seems that android studio wants to download some dependencies and our firewall prevents it from downloading it, just be aware that turning your firewall off may lower the security of your computer. If you have more time you can manually allow your android studio to bypass your firewall, this way you can turn on your firewall while allowing android studio to download anything that it wants.
