android - 找不到support-annotations.jar

Question

我正在尝试按照android测试步骤7中的说明进行操作
https://codelabs.developers.google.com/codelabs/android-testing/#6

克隆了仓库:git clone https://github.com/googlecodelabs/android-testing.git -b step-7
即使删除了对支持注释的所有引用，gradle也会出现相同的错误并停止:

Error:A problem occurred configuring project ':app'.
> Could not find support-annotations.jar (com.android.support:support-annotations:23.1.1).
  Searched in the following locations:      file:/C:/Users/UserName/Documents/android_studio/sdk/extras/android/m2repository/com/android/support/support-annotations/23.1.1/support-annotations-23.1.1.jar

尝试安装依赖项:

echo y | android update sdk --no-ui --all --filter extra-google-google_play_services,extra-google-m2repository

gradle dependencies
