Android版本24.0.0和Espresso 2.0 gradle异常 [英] Android version 24.0.0 and Espresso 2.0 gradle exception

问题描述

我试图在我的应用中使用Espresso 2.0，以测试UI元素。然而，Gradle不会这么做。它给了我这个信息

 错误：与依赖'com.android.support:support-annotations'冲突。应用程序（24.0.0）和测试应用程序（23.1.1）的已解决版本不同。有关详细信息，请参阅http://g.co/androidstudio/app-test-app-conflict。 
  

这是我的 gradle文件

  apply plugin：'com.android.application'
 
 android {
 compileSdkVersion 24 
 buildToolsVersion24.0.0 
 
 defaultConfig {
 applicationIdtheo.testing.espressotutorial
 minSdkVersion 14 
 targetSdkVersion 24 
 versionCode 1 
 versionName1.0

} 
} 
 
 packagingOptions {
 exclude'LICENSE.txt'
} 
} 
 
依赖关系{
编译fileTree（dir：'libs'，include：['* .jar']）
 testCompile'junit：junit：4.12'
 compile'c​​om.android.support： appcompat-v7：24.0.0'
 
 androidTestCompile'c​​om.android.support.test.espresso：espresso-core：2.0'
 
 // Android JUnit Runner 
 androidTestCompile'c​​om.android.support.test：runner：0.5'
 // JUnit4 Rules 
 androidTestCompile'c​​om.android.support.test：rules：0.5'
 } 
  

我应该更新测试跑步者吗？这让我很头疼。

谢谢，

解决方案

Espresso具有导致这些问题的传递依赖关系。您可以从 androidTest 依赖关系中将所有依赖关系排除到组 com.android.support 之外：

  //将Espresso的传递依赖关系排除在组com.android.support中的所有包上
 configurations.androidTestCompile.dependencies.each {androidTestCompileDependency  - > ; 
 androidTestCompileDependency.exclude group：'com.android.support'
} 
  

你应该使用Espresso 2.2.2 ！一个完整的例子：

 依赖项{
 
 def espressoVersion ='2.2.2'
 def testRunnerVersion ='0.5'
 
 androidTestCompilecom.android.support.test：runner：$ {testRunnerVersion}
 androidTestCompilecom.android.support.test：rules：$ {testRunnerVersion }
 androidTestCompilecom.android.support.test.espresso：espresso-core：$ {espressoVersion}
 androidTestCompilecom.android.support.test.espresso：espresso-contrib：$ {espressoVersion }
 androidTestCompilecom.android.support.test.espresso：espresso-intents：$ {espressoVersion}
 
 configurations.androidTestCompile.dependencies.each {androidTestCompileDependency  - > 
 androidTestCompileDependency.exclude group：'com.android.support'
} 
} 
  

I am trying to use Espresso 2.0 in my app,in order to test the UI elements. However the gradle doesn't let do it. It gives me this message

Error:Conflict with dependency 'com.android.support:support-annotations'. Resolved versions for app (24.0.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

This is my gradle file

apply plugin: 'com.android.application'

android {
compileSdkVersion 24
buildToolsVersion "24.0.0"

defaultConfig {
    applicationId "theo.testing.espressotutorial"
    minSdkVersion 14
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"


}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

packagingOptions{
    exclude 'LICENSE.txt'
  }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.0.0'

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.0'

// Android JUnit Runner
androidTestCompile 'com.android.support.test:runner:0.5'
// JUnit4 Rules
androidTestCompile 'com.android.support.test:rules:0.5'
}

Should I updater the test runners? This is giving me a headache.

Thanks,

Theo.

解决方案

Espresso has transitive dependencies that cause those problems. You can just exclude all dependencies to the group com.android.support from your androidTest dependencies:

// Exclude Espresso's transitive dependencies to all packages in group com.android.support
configurations.androidTestCompile.dependencies.each { androidTestCompileDependency ->
    androidTestCompileDependency.exclude group: 'com.android.support'
}

You should use Espresso 2.2.2! A complete example:

dependencies {

    def espressoVersion = '2.2.2'
    def testRunnerVersion = '0.5'

    androidTestCompile "com.android.support.test:runner:${testRunnerVersion}"
    androidTestCompile "com.android.support.test:rules:${testRunnerVersion}"
    androidTestCompile "com.android.support.test.espresso:espresso-core:${espressoVersion}"
    androidTestCompile "com.android.support.test.espresso:espresso-contrib:${espressoVersion}"
    androidTestCompile "com.android.support.test.espresso:espresso-intents:${espressoVersion}"

    configurations.androidTestCompile.dependencies.each { androidTestCompileDependency ->
        androidTestCompileDependency.exclude group: 'com.android.support'
    }
}
