完整报错：

A problem occurred configuring root project '项目名'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Using insecure protocols with repositories, without explicit opt-in, is unsupported. 
　　　　　Switch Maven repository 'maven(http://maven.aliyun.com/nexus/content/groups/public/)' 
　　　　　to redirect to a secure protocol (like HTTPS) or allow insecure protocols. 
　　　　　See https://docs.gradle.org/7.2/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details. 

* Try:

原因：在下载gradle的时候使用不安全的http代理导致。

解决方案：修改你的build.gradle文件中的repositories中的maven，在maven中添加allowInsecureProtocol = true，如：

maven{
  url 'http://maven.aliyun.com/nexus/content/groups/public/'
  allowInsecureProtocol = true
}

或者你可以直接把http改成https试一试。

注：allowInsecureProtocol即允许不安全协议。

OK，Try Agian。
