android- Gradle: An issue occurred configuring root project android studio

Question

I migrated from eclipse to android studio. I've create a new project and I want to run it on genymotion. When I press run icon, it begins to compile and give me this error :

Error:Gradle: A problem occurred configuring root project 'Khabar'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:1.1.0.

This is some parts of my build.gradle :

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "example.ir.khabar"
        minSdkVersion 8
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

build.gradle in root :

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "example.ir.khabar"
        minSdkVersion 8
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:20.0.0'
    compile files('libs/universal-image-loader-1.8.4-with-sources.jar')
}

Could you help me? my gradle version is gradle-2.2.1-all

Answer 1

For me, the solution was to add the http url for jcenter, instead of https:

buildscript {
    repositories {
        jcenter {
            url "http://jcenter.bintray.com/"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

In addition to Al's answer, I also had to put the url inside allprojects:

allprojects {
    repositories {
        jcenter {
            url "http://jcenter.bintray.com/"
        }
    }
}
