Cant find 'com.android.support:design:22.2.0'

I want to use FloatingActionButton

, but for this I need a library:

compile 'com.android.support:design:22.2.0'

      

        
        
        
      

    

But when I add it to my gradle I get the message:

A problem occurred configuring project ':myModule'.
Could not resolve all dependencies for configuration ':myModule:_debugCompile'.
   Could not find com.android.support:design:22.2.0.

I tried updating my Android SDK, but everything is updated:

So why can't it be allowed com.android.support:design:22.2.0

?

This is my gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "de.bla.myProject"
        minSdkVersion 19
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

    buildTypes {
        debug {
            debuggable true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

    compile project(':androidcircularcrop_lib')
