Android版本24.0.0和Espresso 2.0的gradle异常

Question

我试图在我的应用程序中使用Espresso 2.0，以测试UI元素。然而，gradle不允许这样做。它给了我这个信息

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.

这是我的gradle文件

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'
}

我应该更新测试运行程序吗?这真让我头疼。

谢谢,

西奥。

Espresso的传递依赖会导致这些问题。您可以从androidTest依赖项中排除对com.android.support组的所有依赖项:

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

你应该用Espresso 2.2.2 !完整示例:

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'
    }
}
