今天在升级Android项目的gradle时，遇到如下的一个错误：
官方的解释是：
代码语言：javascript复制Specifies whether it is acceptable to communicate with a repository over an insecure HTTP connection.
For security purposes this intentionally requires a user to opt-in to using insecure protocols on case by case basis.
Gradle intentionally does not offer a global system/gradle property that allows a universal disable of this check.
*Allowing communication over insecure protocols allows for a man-in-the-middle to impersonate the intended server, and gives an attacker the ability to [serve malicious executable code onto the system.](https://max.computer/blog/how-to-take-over-the-computer-of-any-java-or-clojure-or-scala-developer/)*大概意思是为了安全，需要要升级成Https，修改的方式有两种。一种是将maven的http修改成为https，另一种是忽略警告，在maven中添加allowInsecureProtocol，比如：
maven {
allowInsecureProtocol = true
url 'http://developer.huawei.com/repo/'
}
