错误关联：Failed to resolve: 、 repository ‘Google’ was added by build file 'build.gradle

首先我导入一个库后编译项目遇到这样的问题：

出现Failed to resolve: com.github.chrisbanes:PhotoView的问题，
你们的工程可能报各种库的问题，但开头都是Failed to resolve:com.github.xxxx.xxxx
则应在项目的 build.gradle 添加如下：

 maven {url"https://jitpack.io"} 

在小狐狸版本之前，只要我们在全局的build.gradle添加即可，例如：

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

注意，下载最新版本的AS，如果在项目的build.gradle中添加项目编译需要的依赖，
然后，报错，编译不过。

problem occurred evaluating root project 'My Application'.
Build was configured to prefer settings repositories over project repositories but repository 'Google' 
was added by build file 'build.gradle

gradle_29">注意： Google最新的项目编译依赖配置改到settings.gradle中了，解决如下：

In settings.gradle you can add the repositories you want to add to the project

dependencyResolutionManagement {
   repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
   repositories {
      google()
      mavenCentral()
      jcenter()
      maven { url 'https://jitpack.io' }
    }
}
