java - 在 Android 构建上找不到 androidTestCompile

Question

继another question之后，已解决。

我正在关注Start Developing for Android Pluralsight 类(class)。我们即将添加测试。说明中表示将 androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2' 添加到 build.gradle 文件(位于app 模块)。

apply plugin: 'com.android.application'

android {
  compileSdkVersion 24
  buildToolsVersion '24.0.3'

  defaultConfig {
    applicationId 'com.sqisland.android.hello'
    minSdkVersion 1
    targetSdkVersion 24
    versionCode 1
    versionName '1.0.0'
  }

  dependencies {
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
  }
}

当我同步构建时，我可能会出现错误:

Error:Execution failed for task ':app:processDebugAndroidTestManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 8 declared in library [com.android.support.test.espresso:espresso-core:2.2.2] F:\BanksySan\Development\PluralSight\android-hello-world\app\build\intermediates\exploded-aar\com.android.support.test.espresso\espresso-core\2.2.2\AndroidManifest.xml
    Suggestion: use tools:overrideLibrary="android.support.test.espresso" to force usage

我应该使用建议的修复吗？目前我认为我更有可能在某个地方缺少一个图书馆。

根据安迪的建议

我已将 block 移到外面，错误是:

Error:Execution failed for task ':app:processDebugAndroidTestManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 1 cannot be smaller than version 8 declared in library [com.android.support.test.espresso:espresso-core:2.2.2] F:\BanksySan\Development\PluralSight\android-hello-world\app\build\intermediates\exploded-aar\com.android.support.test.espresso\espresso-core\2.2.2\AndroidManifest.xml
    Suggestion: use tools:overrideLibrary="android.support.test.espresso" to force usage

Answer 1

将 dependency block 移出 android block ，并将 minSdkVersion 提高到至少 8:

android {  
   minSdkVersion: 8  
   //... 
}

dependencies {   
   // .... 
}
