Question

我正在尝试一件简单的事情：导入一些Google的库以使用Gmail API。我知道mavenCentral中不存在这些罐子中的一些。因此，我从sdk管理器更新了我的Google存储库，并指示gradle查看sdk。我还删除了依赖项末尾的版本号，并将其替换为无法解决我的问题的+，因此回退到original build.gradle文件。

我的build.gradle文件如下所示：

buildscript {
    repositories {
        mavenCentral()


        def androidHome = System.getenv("ANDROID_HOME")
        maven {
            url "$androidHome/extras/android/m2repository/"
        }
    }


    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.0'
    }
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.hellobusiness.hotels"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                'proguard-rules.pro'
        }
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.google.api-client:google-api-client:1.20.0'
    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-gmail:v1-rev29-1.20.0'
}

我得到的错误：

FAILURE: Build failed with an exception.

我将eclipse与adt插件一起使用，并且我从命令行使用gradle

Answer 1

您必须在build.gradle

中添加此部分

repositories {
    mavenCentral()
}

这些库位于Central Maven：

com.google.api-client:google-api-client:1.20.0.
com.google.api-client:google-api-client-android:1.20.0
com.google.api-client:google-api-client-gson:1.20.0

关于这个图书馆，我不知道在哪里。

com.google.apis:google-api-services-gmail:v1-rev29-1.20.0

另外，我建议您使用以下版本：

Android Studio 1.2.x
classpath 'com.android.tools.build:gradle:1.2.3'
gradle 2.4

Gradle无法解析所有依赖项
