Android衝突與依賴appcompat

Question

我想添加espresso-contrib庫到我的項目。這裏是我的build.gradle文件：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "example.com.littlebox_hari" 
     minSdkVersion 19 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
    /*configurations.all { 
     resolutionStrategy { 
      force 'com.android.support:appcompat-v7:23.4.0' 
     } 
    }*/ 
} 


dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.4.0' 
    compile 'com.squareup.retrofit2:retrofit:2.0.0' 
    compile 'com.squareup.retrofit2:converter-gson:2.0.0' 
    androidTestCompile 'com.android.support.test:runner:0.4' 
    androidTestCompile 'com.android.support.test:rules:0.4' 
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1' 
    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2' 
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1' 
    androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2' 
    androidTestCompile 'com.android.support.test.espresso:espresso-idling-resource:2.2.2' 
    compile 'com.android.support:support-annotations:23.4.0' 
    testCompile 'com.android.support:support-annotations:23.4.0' 
    androidTestCompile 'com.android.support:support-annotations:23.4.0' 
} 

我得到這個錯誤：

Error:Conflict with dependency 'com.android.support:appcompat-v7'. Resolved versions for app (23.4.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details. 

如果我取消我的build.gradle文件中的行，我得到：

Error:(72) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Display1'. 
Error:(75) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Caption'. 
Error:(79) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Caption'. 
Error:(76) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Caption'. 
Error:(82) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Caption'. 
Error:(89) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Button'. 
D:\Littlebox-Hari\app\build\intermediates\exploded-aar\com.android.support\design\23.1.1\res\values\values.xml 
Error:(97, 5) No resource found that matches the given name: attr 'textAllCaps'. 
Error:(102, 5) No resource found that matches the given name: attr 'elevation'. 
Error:(113, 5) No resource found that matches the given name: attr 'backgroundTint'. 
Error:(113, 5) No resource found that matches the given name: attr 'elevation'. 
Error:(122, 5) No resource found that matches the given name: attr 'elevation'. 
Error:(131, 5) No resource found that matches the given name: attr 'elevation'. 

編輯：我將以下行添加到了我的build.gradle文件中：

testCompile 'com.android.support:appcompat-v7:23.4.0' 
androidTestCompile 'com.android.support:appcompat-v7:23.4.0' 

我仍然得到相同的錯誤。

Answer 1

我今天也遇到過這個問題。

首先，將依賴項更新爲最新版本（0.5和2.2.2）。

請參見：https://google.github.io/android-testing-support-library/downloads/

// Android JUnit Runner 
androidTestCompile 'com.android.support.test:runner:0.5' 

// JUnit4 Rules 
androidTestCompile 'com.android.support.test:rules:0.5' 

// Espresso core 
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2' 

// Espresso-contrib for DatePicker, RecyclerView, Drawer actions, Accessibility checks, CountingIdlingResource 
androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2' 

// Espresso-web for WebView support 
androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.2' 

// Espresso-idling-resource for synchronization with background jobs 
androidTestCompile 'com.android.support.test.espresso:espresso-idling-resource:2.2.2' 

然後，你會面臨着同樣的錯誤，因爲最新的版本是不是還採用了最新版本的支持庫，截至目前（23.4.0）。有一個在bug跟蹤系統已經打開的問題：https://code.google.com/p/android/issues/detail?id=211490

這爲我工作：

dependencies { 
    ext { 
     supportLibVersion = '23.4.0' 
     espressoVersion = '2.2.2' 
    } 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    androidTestCompile 'com.android.support.test:runner:0.5' 
    androidTestCompile 'com.android.support.test:rules:0.5' 
    androidTestCompile "com.android.support.test.espresso:espresso-core:$espressoVersion" 
    androidTestCompile ("com.android.support.test.espresso:espresso-contrib:$espressoVersion") { 
     exclude module: 'recyclerview-v7' 
     exclude module: 'design' 
    } 
    androidTestCompile "com.android.support.test.espresso:espresso-web:$espressoVersion" 
    androidTestCompile "com.android.support.test.espresso:espresso-idling-resource:$espressoVersion" 
    androidTestCompile "com.android.support:support-annotations:$supportLibVersion" 
    compile "com.android.support:appcompat-v7:$supportLibVersion" 
    compile "com.android.support:design:$supportLibVersion" 
    compile "com.android.support:appcompat-v7:$supportLibVersion" 
    compile "com.android.support:recyclerview-v7:$supportLibVersion" 
} 

編輯： 根據這個代碼路徑guide，好像這是正確的方式：

ext { 
    supportLibVersion = '24.1.1' 
    espressoVersion = '2.2.2' 
    junitVersion = '4.12' 
    mockitoVersion = '1.10.19' 
    hamcrestVersion = '1.3' 
    powerMockitoVersion = '1.6.5' 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile "com.android.support:appcompat-v7:$supportLibVersion" 
    compile "com.android.support:design:$supportLibVersion" 
    compile "com.android.support:recyclerview-v7:$supportLibVersion" 

    // Testing dependencies 
    testCompile "junit:junit:$junitVersion" 
    testCompile "org.mockito:mockito-all:$mockitoVersion" 
    testCompile "org.hamcrest:hamcrest-all:$hamcrestVersion" 
    testCompile "org.powermock:powermock-module-junit4:$powerMockitoVersion" 
    testCompile "org.powermock:powermock-api-mockito:$powerMockitoVersion" 
    androidTestCompile 'com.android.support.test:runner:0.5' 
    androidTestCompile 'com.android.support.test:rules:0.5' 
    androidTestCompile "com.android.support.test.espresso:espresso-core:$espressoVersion" 
    androidTestCompile "com.android.support.test.espresso:espresso-contrib:$espressoVersion" 
    androidTestCompile "com.android.support.test.espresso:espresso-web:$espressoVersion" 
    androidTestCompile "com.android.support.test.espresso:espresso-idling-resource:$espressoVersion" 
} 

configurations.all { 
    resolutionStrategy.force "com.android.support:support-annotations:$supportLibVersion" 
} 

configurations.compile.dependencies.each { compileDependency -> 
    println "Excluding compile dependency: ${compileDependency.getName()}" 
    configurations.androidTestCompile.dependencies.each { androidTestCompileDependency -> 
    configurations.androidTestCompile.exclude module: "${compileDependency.getName()}" 
}

這兩個配置爲我工作後，噸與其他build.gradle文件（閱讀太多的安卓書籍gradle設置有因爲坦率地說Gradle和它的構建系統很糟糕（完全不如CMake/Rake/Scons/Make），所以我們改變了，與來自countles swebsites的黑客Gradle文件合併，並與Gradle文件合併，這些Gradle文件仍然是過時的谷歌自己推薦的gradle文件。

/*主* buid.gradle/

// Top-level build file where you can add configuration options common to all sub-projects/modules. 

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.1.2' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

plugins { 
    id 'java' 
    id "com.github.tkruse.groovysh" version "1.0.8" // optional 
} 


allprojects { 
    repositories { 
     jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

// Define versions in a single place 
ext { 
    // Sdk and tools 
    minSdkVersion = 10 
    targetSdkVersion = 22 
    compileSdkVersion = 23 
    buildToolsVersion = '23.0.3' 

    // App dependencies 
    supportLibraryVersion = '23.4.0' 
    guavaVersion = '18.0' 
    glideVersion = '3.6.1' 
    junitVersion = '4.12' 
    mockitoVersion = '1.10.19' 
    powerMockito = '1.6.2' 
    hamcrestVersion = '1.3' 
    runnerVersion = '0.5' 
    rulesVersion = '0.5' 
    espressoVersion = '2.2.2' 
} 

和

應用/的build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion rootProject.ext.compileSdkVersion 
    buildToolsVersion rootProject.ext.buildToolsVersion 

    defaultConfig { 
     applicationId "com.example.android.testing.notes" 
     minSdkVersion rootProject.ext.minSdkVersion 
     targetSdkVersion rootProject.ext.targetSdkVersion 
     versionCode 1 
     versionName "1.0" 

     testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner' 
    } 
    buildTypes { 
     debug { 
      // Run code coverage reports by default on debug builds. 
      testCoverageEnabled = true 
     } 
    } 

    // If you need to add more flavors, consider using flavor dimensions. 
    productFlavors { 
     mock { 
      applicationIdSuffix = ".mock" 
     } 
     prod { 

     } 
    } 

    // Remove mockRelease as it's not needed. 
    android.variantFilter { variant -> 
     if(variant.buildType.name.equals('release') 
       && variant.getFlavors().get(0).name.equals('mock')) { 
      variant.setIgnore(true); 
     } 
    } 

    // Always show the result of every unit test, even if it passes. 
    testOptions.unitTests.all { 
     testLogging { 
      events 'passed', 'skipped', 'failed', 'standardOut', 'standardError' 
     } 
    } 

}
