这篇博客详细记录了在使用Android Studio Arctic Fox和Gradle 7.0时遇到的问题及其解决方案。包括：1）如何配置允许使用不安全的http仓库；2）解决私有仓库组件依赖失败的问题，需要在settings.gradle中添加仓库配置；3）由于apply plugin: 'maven'不再支持，更新了使用maven-publish插件的发布脚本。作者提供了完整的配置代码示例，帮助开发者顺利进行项目构建和组件发布。

环境

Android Studio Arctic Fox | 2020.3.1 Patch 2
Build #AI-203.7717.56.2031.7678000, built on August 27, 2021
Runtime version: 11.0.10+0-b96-7249189 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
Linux 5.4.0-89-generic

问题1：http协议的仓库不安全

Gradle 7.0默认强制使用https的仓库地址，直接使用的话，会报错如下：

Could not resolve all dependencies for configuration ‘:classpath’.
Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository ‘maven(http://...:8081/repository/maven-public/)’ to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.0.2/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.

解决1：设置allowInsecureProtocol

通过设置 allowInsecureProtocol 为 true，来支持http的仓库地址。详情见官方说明：UrlArtifactRepository:allowInsecureProtocol

buildscript {
    repositories {
        maven {
            allowInsecureProtocol true
            url 'http://xxx.xx.xx.xx:8081/repository/maven-public/'
        }
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.31"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

问题2：私有仓库组件依赖不成功

远程进行依赖时，旧版本可以依赖成功的一个组件，报错：

Failed to resolve: com.xx.xx:utils:1.0.0

1，检查project 的 build.gradle，明明已经设置好了maven地址引用。

buildscript {
    repositories {
        maven {
            allowInsecureProtocol true
            url 'http://xxx.xx.xx.xx:8081/repository/maven-public/'
            credentials {
                username = NEXUS_USERNAME
                password = NEXUS_PASSWORD
            }
        }
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.31"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

发现个问题，旧版本一般都有的allprojects {}，不见了！！！，莫非是换了人间，经查询果然是！！！

2，找到“新人间”，根目录的settings.gradle

修改前

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }
}
rootProject.name = "xxx"
include ':demo'
include ':Library'

修改后

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        maven {
            allowInsecureProtocol true
            url 'http://xxx.xxx.xxx.xxx:8081/repository/maven-public/'
        }
        google()
        mavenCentral()
    }
}
rootProject.name = "xxx"
include ':demo'
include ':Library'

问题3：apply plugin: ‘maven’ 不再支持，原先的上传脚本废了。

原来的脚本

//打包发布

apply plugin: 'maven'

//打包main目录下代码和资源的 task
task androidSourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.srcDirs
}

uploadArchives {
    repositories.mavenDeployer {
        name = 'mavenCentralReleaseDeployer'
        repository(url: MAVEN_URL) {
            authentication(userName: NEXUS_USERNAME, password: NEXUS_PASSWORD)
        }
        snapshotRepository(url: MAVEN_SNAPSHOT_URL) {
            authentication(userName: NEXUS_USERNAME, password: NEXUS_PASSWORD)
        }
        pom.version = "1.1.2-SNAPSHOT"
        pom.artifactId = "xxx"
        pom.groupId = GROUP_ID
        pom.name = "xxx"
        pom.packaging = 'aar'

    }
}

artifacts {
    archives androidSourcesJar
}

新的Publish脚本，确实费了一番周折，参考了android官网： Use the Maven Publish plugin 和 gradle官网：Example 8. Publishing a Java library。

//打包发布

apply plugin: 'maven-publish'

//打包main目录下代码和资源的 task
task androidSourcesJar(type: Jar) {
    classifier = 'sources'
    from android.sourceSets.main.java.srcDirs
}

afterEvaluate {
    publishing {
        publications {
            // Creates a Maven publication called "release".
            release(MavenPublication) {
                // Applies the component for the release build variant. 
                from components.release

                // You can then customize attributes of the publication as shown below.
                groupId = GROUP_ID
                artifactId = 'xxxx'
                version = '1.0.0'
            }
            // Creates a Maven publication called “debug”.
            debug(MavenPublication) {
                // Applies the component for the debug build variant.
                from components.debug

                groupId = GROUP_ID
                artifactId = 'xxx'
                version = '1.0.0-SNAPSHOT'
            }
        }
        repositories {
            maven {
                name = "nexus"
                allowInsecureProtocol true
                url MAVEN_GROUP_URL
                //nexus3没有开启匿名用户访问的话，添加认证信息
                credentials {
                    username = NEXUS_USERNAME
                    password = NEXUS_PASSWORD
                }
                def releasesRepoUrl = MAVEN_URL
                def snapshotsRepoUrl = MAVEN_SNAPSHOT_URL
                url = version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl

            }
        }
    }
}
