如何从 gradle 中的另一个源集中发布第二个库？

Question

我有这个tlib源集

sourceSets {
    val main by getting
    val tlib by creating {
        compileClasspath += main.output
        runtimeClasspath += main.output
    }
    val test by getting {
        compileClasspath += tlib.output
        runtimeClasspath += tlib.output
    }
}

configurations {
    val tlibCompile by getting {
        extendsFrom(configurations["implementation"])
    }
}

我正在想象这样的事情，但这还不完整

publishing {
    publications {
        val tlibSourcesJar by tasks.registering(Jar::class) {
            classifier = "sources"
            from(sourceSets["tlib"].allSource)
        }

        register("mavenTLib", MavenPublication::class) {
            from(components["tlib"])
            artifact(tlibSourcesJar.get())
        }
    }
}

但我明白了

Could not create domain object 'mavenTLib' (MavenPublication)
> SoftwareComponentInternal with name 'tlib' not found.

如何将测试库与主库分开发布？

Answer 1

我这里有一个例子，不幸的是它是用 Groovy 写的，我还不熟悉 Kotlin 的实现方式。
也许它仍然有帮助： https://github.com/thokari/gradle-workshop/blob/master/examples/09-multiple-artifacts/build.gradle
最相关的部分可能是：

outputArchives.each { outputArchive ->
    String logicalName = outputArchive.camelCase()

    // Add archiving tasks.
    // These could be anything with type AbstractArchiveTask (e.g. War, Zip).
    task("${logicalName}Jar", type: Jar) { from configurations."${logicalName}Compile" }
    task("${logicalName}SourceJar", type: Jar) { from sourceSets."${logicalName}".java }

    // Configure the publishing extension added by the 'maven-publish' plugin.
    // For every combination of publication and repository, a task with name
    // publish<publicationName>PublicationTo<repositoryName>Repository is created.
    // The task 'publish' is a shortcut, depending on each one of them.
    publishing {
        publications {

            // Create a publication by calling its name and type.
            "${logicalName}"(MavenPublication) {

                // Override the artifact id, which defaults to the project name.
                artifactId = outputArchive.dashSeparated()

                // Publish the artifacts created by the archiving tasks.
                artifact tasks."${logicalName}Jar"
                artifact(tasks."${logicalName}SourceJar") { classifier 'source' }
            }
        }
    }
}

我也一直想不出如何利用这个 SoftwareComponent 概念。我通过在我创建的归档任务上调用 artifact 方法解决了这个问题，而不是使用 from(component)，我认为这也可以在 Kotlin 中完成。

这在一定程度上可行，但可能不是最好的方法

sourceSets {
    val main by getting
    val tlib by creating {
        compileClasspath += main.output
        runtimeClasspath += main.output
    }
    val test by getting {
        compileClasspath += tlib.output
        runtimeClasspath += tlib.output
    }
}

configurations {
    val tlibCompile by getting {
        extendsFrom(configurations["implementation"])
    }
}

publishing {
    publications {
        val tlibJar by tasks.registering(Jar::class) {
            from(sourceSets["tlib"].output)
        }

        val tlibSourcesJar by tasks.registering(Jar::class) {
            archiveClassifier.set("sources")
            from(sourceSets["tlib"].allSource)
        }

        register("mavenTLib", MavenPublication::class) {
            artifactId = "phg-entity-tlib"
            artifact(tlibJar.get())
            artifact(tlibSourcesJar.get())
        }
    }
}

如何从 gradle 中的另一个源集中发布第二个库？
