在 `gradle dependencies` 的输出中,我在哪里可以找到 `(*)` 和 `1.7.6 -> 1.7.7` 的文档

Where can I find the document for `(*)` and `1.7.6 -> 1.7.7` in the output of `gradle dependencies`

对于具有简单 build.gradle 文件的 gradle 项目:

apply plugin: 'java'

repositories.jcenter()

dependencies {
    compile "org.springframework.boot:spring-boot-starter-web:1.1.5.RELEASE"
    compile 'org.slf4j:slf4j-api:1.7.1'
}

当我运行gradle dependencies时,会显示:

:dependencies

------------------------------------------------------------
Root project
------------------------------------------------------------

archives - Configuration for archive artifacts.
No dependencies

compile - Compile classpath for source set 'main'.

有两件事我不太确定,虽然我已经阅读了一些文章:

  1. (*) 表示此依赖项已经存在并在前面的步骤中下载
  2. 1.7.1 -> 1.7.7这个依赖声明为1.7.1,但是gradle决定在冲突解决后使用1.7.7

不知道我的理解对不对,请问如何找官方文档解释一下?我搜索了 gradle 网站,但还没有找到

虽然不是官方文档,但我在 gradle dependency-resolution-reporting.md design-doc 中找到了以下内容:

  • avoid regression of current features:
    • subtree is omitted (*)

但是请注意,此设计文档已于 4 月 2 日更改(请参阅更改 here)作为 v2.5 发布工作的一部分,此评论已从此文档中删除。
