Android与依赖项appcompat的冲突

Question

我正在尝试将espresso-contrib库添加到我的项目中.这是我的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'
}

我收到此错误:

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.

如果我取消注释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:(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'.

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'.

编辑:我在build.gradle文件中添加了以下行:

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

我仍然得到同样的错误.

Answer 1

我今天也遇到了这个问题.

首先,将依赖项更新为其最新版本(0.5和2.2.2).

请参阅: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'

然后,您将面临同样的错误,因为最新版本目前尚未使用最新版本的支持库(23.4.0).已经在错误跟踪器上打开了一个问题:https://code.google.com/p/android/issues/detail？id = 211490

这对我有用:

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"
}

编辑: 根据此代码路径指南,似乎这是正确的方法:

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()}"
}
