gradle - 从复制任务发布工件

Question

我的 gradle 构建副本文件。我想使用复制任务的输出作为 maven 工件发布的输入

例子 :

task example(type: Copy) {
    from "build.gradle" // use as example
    into "build/distributions"
}

publishing {
    publications {
        mavenJava(MavenPublication) {
            artifact example
        }
    }
}

但 gradle 不喜欢它:

 * What went wrong:
 A problem occurred configuring project ':myproject'.
 > Exception thrown while executing model rule: PublishingPlugin.Rules#publishing(ExtensionContainer)
     > Cannot convert the provided notation to an object of type MavenArtifact: task ':myproject:example'.
       The following types/formats are supported:
       - Instances of MavenArtifact.
       - Instances of AbstractArchiveTask, for example jar.
       - Instances of PublishArtifact
       - Maps containing a 'source' entry, for example [source: '/path/to/file', extension: 'zip'].
       - Anything that can be converted to a file, as per Project.file()

为什么 ？

据我了解，任务示例的输出应该由 Copy 任务设置。我假设它可以转换为某些文件。所以它应该用作发布任务的输入，作为文件。但是错误消息告诉我我错了。

我该如何解决？

谢谢

Gradle 不知道如何转换 Copy任务到 MavenArtifact , AbstractArchiveTask , PublishArtifact , .... 哪位解释一下错误信息。

但是 它确实知道如何转换 String作为 File ，正如在错误消息的最后一行中所解释的那样。

问题是如何强制 Gradle 在发布之前构建我的任务。 MavenArtifact有一个 builtBy方法就是在这里!

task example(type: Copy) {
    from "build.gradle" // use as example
    into "build/distributions"
}

publishing {
    publications {
        mavenJava(MavenPublication) {
           // file to be transformed as an artifact
           artifact("build/distributions/build.gradle") {
               builtBy example // will call example task to build the above file
           }
        }
    }
}
