Gradle error

[metes]

Gradle did not work as well as readme. It works by adding it like this.

compile 'com.github.orangegangsters:library:1.3.4@aar'   //CircularBarPager    
//this line returns error -> compile 'com.viewpagerindicator:library:2.4.1@aar'
compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'   // new line for PageIndicator
//Animations and progress value easing
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.daimajia.easing:library:1.0.1@aar'`

have you added these lines?

allprojects {
    repositories {
        maven { url 'http://dl.bintray.com/populov/maven/' }
        jcenter()
    }
}

although I added maven and jcenter repositories I have the same problem.
