java - Gradle Play-Services AAR依赖项不起作用

Question

我正在编写一个Java jar 库。我只想为gradle的项目添加play-services依赖项。我的gradle构建脚本:

Properties local = new Properties()
local.load(project.file('local.properties').newDataInputStream())

ext {

    gdxVersion = '1.9.2';
    sdkPath = local.getProperty("sdk.dir")
}

repositories {

    maven { url "$sdkPath\\extras\\google\\m2repository\\" }
    maven { url "$sdkPath\\extras\\android\\m2repository\\" }

    maven { url "https://oss.sonatype.org/content/repositories/releases/" }

    mavenCentral()
}

apply plugin: 'java'
apply plugin: 'idea'

buildDir = 'gen'
libsDirName = '../bin'

sourceCompatibility = 1.8

sourceSets {

     main {

         java {

             srcDir 'src'
         }
     }
}

dependencies {

    compile "com.google.android.gms:play-services-ads:9.0.2";
    compile "com.google.android:android:4.1.1.4"
    compile "com.badlogicgames.gdx:gdx:$gdxVersion"
    compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
}

clean {

    delete fileTree(project.libsDir)
}

Gradle同步完成得很好，android studio告诉一切正常，但是当我尝试构建时:

error: package com.google.android.gms.ads does not exist

Google支持存储库和库已安装。

我的gradle版本2.13。
我也使用了最新的gradle版本候选。没有。

问题出在gradle脚本上。如果要构建和依赖关系，则需要使用gradle插件'com.android.library'。

buildscript {

    repositories {

        maven { url "https://oss.sonatype.org/content/repositories/releases/" }

        mavenCentral()
    }

    dependencies {

        classpath "com.android.tools.build:gradle:2.1.2"
    }
}

apply plugin: 'com.android.library'
