我尝试了不同的 IDE 和操作系统，但有相同的错误。也许我做错了什么？

Intellij Idea Ultimate 中的步骤：

  1. 创建新的 Android 应用程序项目。
  2. 将 espresso-1.1-bundled.jar 复制到 libs 文件夹中。
  3. 添加为库。
  4. 构建项目。

结果：

    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
