java - Android 测试 Espresso 添加 jar 错误

Question

<小时/>

我尝试过不同的IDE和操作系统，但出现同样的错误。也许我做错了什么？

Intellij Idea Ultimate 中的步骤:

1. Create new Android application project.
2. Copy espresso-1.1-bundled.jar in libs folder.
3. Add as library.
4. Build project.

结果:

Answer 1

    Make sure you have installed the latest Android Support Repository under Extras (see instructions).
    Open your app’s build.gradle file. This is usually not the top-level build.gradle file but app/build.gradle.
    Add the following lines inside dependencies:

androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test:runner:0.5
