与依赖'com.android.support：support-annotations'冲突。 应用程序（23.1.0）和testing应用程序（23.0.1）的已解决版本不同
build设时，我得到以下错误：
Conflict with dependency 'com.android.support:support-annotations'. Resolved versions for app (23.1.0) and test app (23.0.1) differ. 这些是我的gradle依赖关系

我怎样才能解决这个问题？
您可以使用以下命令在您的testing中强制注记库：
androidTestCompile 'com.android.support:support-annotations:23.1.0'
像这样的东西：
// Force usage of support annotations in the test app, since it is internally used by the runner module. androidTestCompile 'com.android.support:support-annotations:23.1.0' androidTestCompile 'com.android.support.test:runner:0.4.1' androidTestCompile 'com.android.support.test:rules:0.4.1' androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1' androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1' androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'
另一个解决scheme是在顶层文件中使用它：
configurations.all { resolutionStrategy.force 'com.android.support:support-annotations:23.1.0' }
来源： CodePath – 用Espresso进行UItesting
- 最后，我们需要拉入Espresso依赖关系，并在我们的应用程序build.gradle中设置testing运行器：
// build.gradle ... android { ... defaultConfig { ... testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } } dependencies { ... androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') { // Necessary if your app targets Marshmallow (since Espresso // hasn't moved to Marshmallow yet) exclude group: 'com.android.support', module: 'support-annotations' } androidTestCompile('com.android.support.test:runner:0.5') { // Necessary if your app targets Marshmallow (since the test runner // hasn't moved to Marshmallow yet) exclude group: 'com.android.support', module: 'support-annotations' } }
我已经添加到我的gradle文件，警告消失了。
另外，如果你得到了任何其他的依赖列表，如支持注释，请尝试从androidTestCompile依赖关系中排除它。
你可以尝试使用
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' })
代替
androidTestCompile 'com.android.support.test:runner:0.4.1' androidTestCompile 'com.android.support.test:rules:0.4.1' androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1' androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'
