Recently I have updated my Android Studio to latest version from Latest Android Studio Canary Build: 2.0 Preview
After updating to the new version, my current working directory stop working at all. Every single time when I am trying to clean and build a project they will give me an error like this
Blockquote 'Error:Could not find com.android.tools.build:gradle:2.0.0-alpha2. Searched in the following locations: file:/Applications/Android Studio.app/Contents/gradle/m2repository/com/android/tools/build/gradle/2.0.0-alpha2/gradle-2.0.0-alpha2.pom file:/Applications/Android Studio.app/Contents/gradle/m2repository/com/android/tools/build/gradle/2.0.0-alpha2/gradle-2.0.0-alpha2.jar https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.0.0-alpha2/gradle-2.0.0-alpha2.pom https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.0.0-alpha2/gradle-2.0.0-alpha2.jar Required by: :android 3:unspecified'
Anyone have an idea how to solve this problem. Thanks in advance.
UPDATE: I am using a Mac machine and installation directory look like

Apparently the build tools have been moved from maven to jcenter so you need to change the code from:
buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha2' } }
to this
buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha2' } }

In the main build.gradle file, add jcenter() as main repo, just like that :
buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.5.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() } }
Remove other repositories or make sure jcenter is the first one.

buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.3.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } repositories block should be in buildscript.

Check to see if gradle 2.0.0-alpha1 is available on your system. Look in your android/tools/build/gradle folder. In my case, despite the confusing message "This project is using a preview version of the Gradle plugin (2.0.0-alpha2) and a newer version is available (2.0.0-alpha2) You can update to 2.0.0-alpha2." the version in my folder was 2.0.0-alpha1, and changing my build.gradle to: classpath 'com.android.tools.build:gradle:2.0.0-alpha1' fixed my build problem.

I removed the newest folder gradle-4.1-all in C:\Users\YOUR_USER_NAME\ .gradle\wrapper\dists\ and then I created a new project in Android Studio and the following message disappeared:
"Gradle sync failed: Could not find com.android.tools.build: Gradle: 3.0.0-beta6. "

buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.3.3' classpath 'com.google.gms:google-services:3.0.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { maven { url "https://maven.google.com" } maven { url "https://jitpack.io" } jcenter() } } task clean(type: Delete) { delete rootProject.buildDir }
