错误：与项目'：app'中的依赖项'com.android.support:support-v4'发生冲突。 应用（25.3.1）和测试应用（23.1.1）的已解决版本不同

Question

每当我尝试通过以下依赖项添加Esspreso UI测试库的依赖项以在为RecyclerView开发UI测试以获取RecyclerViewActions时使用此依赖项时，都会出现此错误。

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

同时删除以前的依赖gradle完美构建时，谁能帮助我解决这个问题？ 从我的gradle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'
        })

    }

更新

搜寻了一个小时后，我通过如下设置此依赖项在Vogella中找到了解决方案：

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'
}

您只需要排除build.gradle已经提供的每个库build.gradle
