Приложение с WebView на Android

Здарова ребята. Мой первый раз.

При компиляции приложения в event log:

  17:47 Executing tasks: [assemble]
17:47   Gradle build finished with 1 error(s) in 640ms
17:47   Gradle sync started
17:47   Gradle sync failed: Cause: peer not authenticated
            Consult IDE log for more details (Help | Show Log)

и

Error:Cause: peer not authenticated

В build.gradle :

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'
        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
    }
    buildscript {
        System.properties['com.android.build.gradle.overrideVersionCheck'] = 'true'
    }
}
allprojects {
    repositories {
        jcenter()
    }
}
android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'
}
dependencies {
}

в gradle-wrapper.properties:

#Wed Aug 12 03:05:00 CEST 2015
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-all.zip

Ребят, кто поможет, спасибо.
