問題描述

Gradle7下使用http私庫(kù)時(shí)，提示要使用 https, 可以使用 allowInsecureProtocol true 關(guān)閉。

Could not resolve all dependencies for configuration ':compileClasspath'.
Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven(http://127.0.0.1:8081/repository/maven-public/)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.1/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details. 

但是該屬性在舊版Gradle（例如5.6.2）中不存在，會(huì)提示錯(cuò)誤；

解決方式

init.gradle 文件位置： C:\Users\[用戶名]\.gradle

在init.gradle中，檢查 ArtifactRepository 對(duì)象中是否存在 allowInsecureProtocol屬性，如果存在才設(shè)置，否則忽略；最終 init.gradle 配置文件如下。

allprojects {
    def REPOSITORY_URL = 'http://127.0.0.1:8081/repository/maven-public/'
    repositories {
        mavenLocal()
        maven { ArtifactRepository repo ->
            // 判斷屬性是否存在，之后再設(shè)置
            if (repo.metaClass.hasProperty(repo, 'allowInsecureProtocol')) {
                allowInsecureProtocol true
            }
            url REPOSITORY_URL
        }
        mavenCentral()
    }

    buildscript {
        repositories {
            mavenLocal()
            maven { ArtifactRepository repo ->
                // 判斷屬性是否存在，之后再設(shè)置
                if (repo.metaClass.hasProperty(repo, 'allowInsecureProtocol')) {
                    allowInsecureProtocol true
                }
                url REPOSITORY_URL
            }
            mavenCentral()
        }
    }
}
