我自己回答问题:

将 maven { url 'https://maven.google.com' } 添加到:

allprojects {
    repositories {
        ...
        maven { url 'https://maven.google.com' }//this line is added
        mavenCentral()
        jcenter()
    }
}

对我有用，因为我的 gradle 版本是 3.x.我认为@shizhen 的答案也是正确的，但gradle 版本应该更改为4.x+.

worked for me because my gradle version was 3.x. I think the answer of @shizhen is also correct but the gradle version should be changed to 4.x+.

更多信息参考google() 和 maven { url 'https://maven.google.com' }
