下面记录一下变动：

  1. repositories变动
    /project/build.gradle 内的 allprojects 节点移动到了 /project/settings.gradle，内容如下：

    dependencyResolutionManagement {
        repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
        repositories {
            google()
            mavenCentral()
            jcenter() // Warning: this repository is going to shut down soon
            flatDir {
                dirs 'libs'
            }
        }
    }
  2. libs目录变动
    从以上flatDir配置看到，’libs’ 就是当前目录下的 libs 目录
    libs目录默认由 /project/module/libs 改为 /project/libs 。
    不设置flatDir，项目构建时会提示错误。
