Android 中使用 Google API 的依赖 apache HTTP 客户端

我一直在使用 Google Play 服务库，仅通过 Google+ 登录，效果很好，但现在我想将日历 API 包含到我的应用程序中。我正在关注本教程 https://developers.google.com/google-apps/calendar/quickstart/android

问题是与本教程的新指令的依赖关系导致 Gradle 构建中出现警告。

这是我的 gradle 应用程序文件：

apply plugin: 'com.android.application'

android {
    signingConfigs {
        config {
            keyAlias 'androiddebugkey'
            keyPassword 'android'
            storeFile file('C:/Users/Julio/.android/debug.keystore')
            storePassword 'android'
        }
    }
    compileSdkVersion 22
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.example.julio.competicionpartido"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"

        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            signingConfig signingConfigs.config
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.google.android.gms:play-services:7.5.0'
    compile ('com.google.api-client:google-api-client:1.20.0'){
        exclude module: 'httpclient' 
        exclude group: 'org.apache.httpcomponents'
        exclude group: 'org.apache.httpcomponents', module: 'httpclient' 
    }
    compile 'com.google.api-client:google-api-client-android:1.20.0'
    compile 'com.google.api-client:google-api-client-gson:1.20.0'
    compile 'com.google.apis:google-api-services-calendar:v3-rev125-1.20.0'
}

我已经寻找了很长时间并且尝试了一切。有人可以帮助我吗？

为了将该类排除在外all配置：

configurations.all() {
    exclude group: "org.apache.httpcomponents", module: "httpclient"
}

dependencies {
    ...
}
