upload - 为什么 uploadArchives 会从其他配置上传 Artifact ？

Question

我很困惑为什么 Gradle 的 uploadArchive 会从其他配置上传 Artifact 。我的理解是，当您声明配置时，它将为您获取上传任务，并且在调用时它将上传分配给其配置的 Artifact 。

这不是我看到的行为:

apply plugin: 'base'

configurations {
  foo
}

task fooIt(type: Zip) {
  from 'blah.txt'
  baseName 'foo'
}

task barIt(type: Zip) {
  from 'blah.txt'
  baseName 'bar'
}

artifacts {
  foo fooIt
}

repositories {
  flatDir {
    name 'local'
    dirs 'repo'
  }
}

uploadArchives {
  repositories {
    add project.repositories.local
  }
}

uploadFoo {
  repositories {
    add project.repositories.local
  }
}

在此示例中，没有为 archives 配置分配任何 Artifact ，但当我调用 gradle uploadArchives 时，它将上传 foo 的 Artifact 。

$ gradle -i uploadArchives
All projects evaluated.
Selected primary task 'uploadArchives' from project :
Tasks to be executed: [task ':fooIt', task ':uploadArchives']
:fooIt (Thread[Daemon Thread 17,5,main]) started.
:fooIt
Skipping task ':fooIt' as it is up-to-date (took 0.008 secs).
:fooIt UP-TO-DATE
:fooIt (Thread[Daemon Thread 17,5,main]) completed. Took 0.017 secs.
:uploadArchives (Thread[Daemon Thread 17,5,main]) started.
:uploadArchives
Executing task ':uploadArchives' (up-to-date check took 0.0 secs) due to:
  Task has not declared any outputs.
Publishing configuration: configuration ':archives'
Publishing to Repository 'local'
Published :gradle:unspecified:foo.zip to file:/private/tmp/gradle/repo/foo-unspecified.zip
Published :gradle:unspecified:ivy.xml to file:/private/tmp/gradle/repo/ivy-unspecified.xml
:uploadArchives (Thread[Daemon Thread 17,5,main]) completed. Took 0.017 secs.

BUILD SUCCESSFUL

由此产生的两个问题:

1. 为什么 fooIt 被执行？
2. 为什么 uploadArchives 上传 foo 的 Artifact ？

谢谢

Answer 1

archives配置包含所有配置的所有 Artifact 。我相信这种困惑来自于这样一个事实:您还可以将 Artifact 直接添加到 archives 中。如果你想要配置。既然如此，uploadArchives任务将始终上传所有声明的 Artifact 。如果您想上传 Artifact 的子集，那么您应该调用 upload<<ConfigurationName>>任务。
