android - Gradle构建工具找不到play-services-tasks.aar？为什么？

Question

今天突然，当我尝试在Android Studio中运行我的应用程序时出现错误。

它是:

Error: Could not find play-services-tasks.aar (com.google.android.gms:play-services-tasks:15.0.1).
Searched in the following locations:
    https://jcenter.bintray.com/com/google/android/gms/play-services-tasks/15.0.1/play-services-tasks-15.0.1.aar

我没有更改gradle文件中的任何内容，但它突然出现了。我之前的构建在几分钟前成功执行。

为什么找不到com.google.android.gms:play-services-tasks:15.0.1的一部分play-services-tasks.aar
已采取的步骤:

我检查了我是否将所有存储库都包括在gradle文件中，并且到目前为止都正确。

为什么突然出现此错误？

我也将此链接https://jcenter.bintray.com/com/google/android/gms/play-services-tasks/15.0.1/play-services-tasks-15.0.1.aar复制到了浏览器中，但是工作正常，即出现了“文件下载”对话框。

执行以下更改后，错误消失了:

从应用程序build.gradle的存储库中删除了maven { url 'https://maven.google.com' }。

在所有项目/存储库中的顶层build中添加了maven { url 'https://maven.google.com' }作为的第一项。gradle

将所有播放服务和firebase依赖项更改为最新版本

将google-services插件的版本更改为classpath 'com.google.gms:google-services:4.0.1'
