前言：运行android项目报错：
A problem occurred configuring root project 'xxx'.
> 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.
解决方案：把maven中的http改为https即可。
