gradle：secure protocol | like HTTPS or allow insecure protocols

最近在编译cruise-control-2.5.92，gradle提示

Using insecure protocols with repositories, without explicit opt-in, has been deprecated. This is scheduled to be removed in Gradle 7.0. Switch Maven repository 'maven(http://maven.aliyun.com/nexus/content/groups/public/)' to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/6.8.3/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.Configuration on demand is an incubating feature.

解决方法：

repositories {    ...            maven {        allowInsecureProtocol = true        ...    }}
