Android studio ERROR: Failed to resolve: com.android.support.test.espresso:espresso-core:2.2.2

ERROR: Failed to resolve: com.android.support.test.espresso:espresso-core:2.2.2

ERROR: Failed to resolve: com.android.support:appcompat-v7:25.3.1

Android studio跑別人的項目，經常會出現這種不匹配的情況。
解決方法：
1.

2.添加

maven {
    url "https://maven.google.com"
}

 

結果：

allprojects {
    repositories {
        jcenter()
        maven { url "https://maven.google.com" }
    }
}
