Android Studio Gradle Sync Unable to find the library

So I’m working on a project in AndroidStudio 0.8.1 beta, and I want to use the library I found on github (https://github.com/derekbrameyer/android-betterpickers). I’m in Add dependencies in README.md, but when I try to synchronize the project with the gradle file, it says:

Failed to find: com.doomonafireball .betterpickers:library:1.5.2

This is my build.gradle file:

apply plugin:'com.android. application'
buildscript {
 repositories {
 maven {url'http://repo1.maven.org/maven2' }
 }
}
< br />repositories {
 mavenCentral()
}

android {
 compileSdkVersion 19
 buildToolsVersion '19.1.0'
 defaultConfig {< br /> applicationId'gtsarandum.syncc'
 minSdkVersion 14
 targetSdkVersion 19
 versionCode 1
 versionName '1.0'
 }
 buildTypes {
 release {
 runProguard false
 proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
 }
 }
 productFlavors {
 }
 }

dependencies {
 compile fileTree(dir:'libs', include: ['*.jar'])
 compile'com.android.support:support-v4: 19.+'
 compile project(':extendedCalendarView')
 compile project(':src')
 compile'com.github.gabrielemariotti.cards:library:1.7.3'
 compile'com.github.gabrielemariotti.cards:library-extra:1.7.3'
 compile'com.doomonafireball.betterpickers:library:1.5.2'
}

Last time I encountered the problem of gabriellemariotti.cards: libraryd: 1.7.3 I added maven {url’http://repo1.maven.org/maven2′}.

I Is there anything else I need to add? If not, how can I solve this problem?

Thanks in advance!

Try to use the include statement to change ‘gradle.settings’, the path/lib cannot be found.
