如何将Android库的maven-publish与signing插件从Groovy DSL迁移至Kotlin DSL？

以下是你提供的Groovy DSL代码对应的Kotlin DSL版本，适配maven-publish和signing插件：

plugins {
    `maven-publish`
    signing
}

android {
    publishing {
        singleVariant("release") {
            withJavadocJar()
            withSourcesJar()
        }
    }
}

publishing {
    publications {
        create<MavenPublication>("release") {
            afterEvaluate {
                from(components["release"])
            }

            groupId = project.property("groupId") as String
            artifactId = project.property("artifactId") as String
            version = project.property("version") as String
        }
    }

    repositories {
        maven {
            url = uri("https://s01.oss.sonatype.org/service/local/staging/deploy/maven2/")
            credentials {
                username = project.property("sonatypeUsername") as String
                password = project.property("sonatypePassword") as String
            }
        }
    }
}

signing {
    sign(publishing.publications["release"])
}

关键转换点说明： #

• 插件声明：Kotlin DSL中，带连字符的maven-publish需要用反引号包裹，signing可直接使用
• 组件引用：Kotlin里访问组件需通过索引方式components["release"]，替代Groovy的直接属性调用
• 属性获取：必须明确调用project.property()，并将返回的Any类型强转为String，符合Kotlin类型安全要求
• 仓库URL配置：Kotlin DSL需用uri()包裹URL字符串，替代Groovy的直接赋值
• 签名配置：通过索引publishing.publications["release"]获取发布配置，传递给sign()方法
