apply plugin: 'kotlin-android-extensions'

android {
 compileSdkVersion 25
 buildToolsVersion "25.0.2"
 defaultConfig {

   minSdkVersion 15
   targetSdkVersion 25
   versionCode 1
   versionName "1.0"
   testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
 }
 buildTypes {
   release {
     minifyEnabled false
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
   }
 }
}

dependencies {
 compile fileTree(dir: 'libs', include: ['*.jar'])
 androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
   exclude group: 'com.android.support', module: 'support-annotations'
 })
 compile 'com.android.support:appcompat-v7:25.3.1'
 compile 'com.android.support.constraint:constraint-layout:1.0.2'
 testCompile 'junit:junit:4.12'<br>
 compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
 compile "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
}

repositories {
 maven {url 'http://maven.aliyun.com/nexus/content/groups/public/'}
}

Project的build.gradle

buildscript {
 ext.kotlin_version = '1.1.2-4'
 repositories {
   maven {url 'http://maven.aliyun.com/nexus/content/groups/public/'}
 }
 dependencies {
   classpath 'com.android.tools.build:gradle:2.3.2'
   classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

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

allprojects {
 repositories {
   maven {url 'http://maven.aliyun.com/nexus/content/groups/public/'}
 }
}

task clean(type: Delete) {
