Android Studio: Gradle Refresh Failed - Could not find com.android.tools.build:gradle:2.2.0-alpha6 -

i've pulled down android project git, , android studio giving me following error whenever attempt open it;

error:could not find com.android.tools.build:gradle:2.2.0-alpha6. searched in following locations:     https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.0-alpha6/gradle-2.2.0-alpha6.pom     https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.0-alpha6/gradle-2.2.0-alpha6.jar     https://maven.fabric.io/public/com/android/tools/build/gradle/2.2.0-alpha6/gradle-2.2.0-alpha6.pom     https://maven.fabric.io/public/com/android/tools/build/gradle/2.2.0-alpha6/gradle-2.2.0-alpha6.jar required by:     newapp_android:app:unspecified 

i've installed gradle locally, , set environment paths via system.

under project structure/project, following setup in use;

gradle version : 2.10 android plugin version : 2.2.0-alpha6 android plugin repository : jcenter default library repository : jcenter 

could point me in right direction on this?

this because build process unable find dependency in maven repository. add jcenter() along mavencentral() in project level build.gradle file.

buildscript {     repositories {         mavencentral()         jcenter()     }     dependencies {         classpath 'com.android.tools.build:gradle:2.2.0'     } }
