如何将Android Library各Flavor发布到对应独立Maven仓库？

你当前的配置会让两个发布变体推送到所有仓库，这是因为maven-publish默认会为每个发布项和仓库的组合生成发布任务。要实现internalRelease只推送到internal仓库、externalRelease只推送到external仓库，只需添加任务过滤逻辑即可：

修改后的完整配置如下：

flavorDimensions += "version"
productFlavors {
    create("external") {
        dimension = "version"
    }
    create("internal") {
        dimension = "version"
    }
}

publishing {
    singleVariant("externalRelease")
    singleVariant("internalRelease")
}

afterEvaluate {
    val releaseVersion = "1.0.10"
    publishing {
        publications {
            register<MavenPublication>("internalRelease") {
                groupId = "com.company"
                artifactId = "internal"
                version = releaseVersion

                afterEvaluate {
                    from(components["internalRelease"])
                }
            }
            register<MavenPublication>("externalRelease") {
                groupId = "com.company"
                artifactId = "external"
                version = releaseVersion

                afterEvaluate {
                    from(components["externalRelease"])
                }
            }
        }
        repositories {
            maven {
                name = "internal"
                url = uri("https://urltomyinternal")
                authentication {
                    create<BasicAuthentication>("basic")
                }
                credentials {
                    username = project.properties["mavenUsername"].toString()
                    password = project.properties["mavenPassword"].toString()
                }
            }
            maven {
                name = "external"
                url = uri("https://urltomyexternal")
                authentication {
                    create<BasicAuthentication>("basic")
                }
                credentials {
                    username = project.properties["mavenUsername"].toString()
                    password = project.properties["mavenPassword"].toString()
                }
            }
        }
    }

    // 过滤发布任务，只允许对应发布项推送到匹配的仓库
    tasks.withType<PublishToMavenRepository>().configureEach {
        when (publication.name) {
            "internalRelease" -> onlyIf { repository.name == "internal" }
            "externalRelease" -> onlyIf { repository.name == "external" }
        }
    }
}

代码说明： #

• tasks.withType<PublishToMavenRepository>().configureEach：遍历所有Maven发布任务
• 通过publication.name和repository.name的匹配关系，用onlyIf控制任务是否执行：
  • 当发布项是internalRelease时，仅允许推送到名称为internal的仓库
  • 当发布项是externalRelease时，仅允许推送到名称为external的仓库

这样执行发布时，internalRelease只会推送到内部仓库，externalRelease只会推送到外部仓库，不会出现交叉发布的情况。
