Error:Conflict with dependency 'com.android.support:support-v4' in project ':app'. Resolved versions for app (25.3.1) and test app (23.1.1) differ

Question

每次我尝试通过以下依赖项添加 Esspreso UI 测试库的依赖项以在开发 UI 测试 RecyclerView 以获取 RecyclerViewActions 时使用它时，我都会收到此错误。

 androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2'

在删除之前的依赖项时 gradle 正在完美构建谁能帮我解决这个问题？？来自我的 gradle 的样本：

 dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
       compile 'com.android.support:appcompat-v7:25.3.1'
        compile 'com.android.support.constraint:constraint-layout:1.0.2'
        compile 'com.android.support:recyclerview-v7:25.3.1'
        compile 'com.android.support:cardview-v7:25.3.1'
        compile 'com.squareup.okhttp3:okhttp:3.6.0'
        compile 'com.github.bumptech.glide:glide:4.0.0-RC0'
        testCompile 'junit:junit:4.12'

        compile 'com.jakewharton:butterknife:8.6.0'
        annotationProcessor 'com.jakewharton:butterknife-compiler:8.6.0'
        annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0-RC0'

        compile 'com.google.android.exoplayer:exoplayer:r2.2.0'

        androidTestCompile( 'com.android.support.test.espresso:espresso-intents:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        androidTestCompile( 'com.android.support.test:rules:0.5', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        androidTestCompile ('com.android.support.test:runner:0.5', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        androidTestCompile ('com.android.support.test.espresso:espresso-web:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        androidTestCompile( 'com.android.support.test.espresso:espresso-contrib:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })

    }

Update

After googling for an hour I found the solution within Vogella by setting this dependency as following:

androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2') {
        exclude group: 'com.android.support', module: 'appcompat'
        exclude group: 'com.android.support', module: 'support-v4'
        exclude group: 'com.android.support', module: 'support-annotations'
        exclude module: 'recyclerview-v7'
    }

Answer 1

这将解决您的问题：

androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2.2') {
    exclude group: 'com.google.code.findbugs'
    exclude group: 'com.android.support', module: 'appcompat-v7'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude group: 'com.android.support', module: 'design'
    exclude module: 'recyclerview-v7'
}

您只需排除已在 build.gradle

中提供的每个库
