Gradle無法解決所有依賴關係

Question

我在嘗試一件簡單的事情：導入一些Google的庫以便使用Gmail API。我知道mavenCentral上不存在這些罐中的一些。因此，我從sdk管理器更新了我的Google知識庫，並指示gradle查看sdk。我還刪除了依賴關係末尾的版本號，並用一個+替換了它們，這並不能解決我的問題，因此會回退到originalbuild.gradle文件。

我build.gradle文件看起來像這樣：

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' 
} 

的錯誤，我得到：

我與ADT插件使用Eclipse，我使用gradle這個命令行

Answer 1

你有將此零件添加到您的build.gradle

repositories { 
    mavenCentral() 
} 

個

這些庫在Maven中央：

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 

關於這個庫，我不知道在哪裏。

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

此外，我建議你使用的版本：

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