我的build.gradle项目文件如下：

buildscript {
    repositories {
        jcenter()
        google()
        maven { url 'https://maven.google.com' }
        maven { url 'https://jitpack.io' }
        mavenCentral()
        maven { url "http://nexus.trifork.com/content/repositories/releases" }
        maven { url "http://dl.bintray.com/riteshakya037/maven" }
    }

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

allprojects {
