推荐答案

在发布时，jCenter在处理某些工件时存在/正在出现问题. 此gradle问题跟踪修复过程以及bintray的

At the time of posting, jCenter is/was having an issue serving certain artifacts. This gradle issue tracks progress on the fix, and bintray's status page has an entry for March 17, 2018 detailing the problem.

一个临时的解决方法是使用mavenCentral而不是jCenter(或至少首先使用它).

A temporary workaround is to use mavenCentral instead of jCenter (or at least use it first).

这可以通过更改存储库gradle的使用来完成.由于这是一个android项目，因此约定似乎按如下方式使用allprojects:

This can be done by changing the repositories gradle uses. Since this is an android project the convention seems to be using allprojects as follows:

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()
    }
}
