maven - 使用单个存储库和单个镜像的区别

Question

Maven 文档说:

http://maven.apache.org/guides/mini/guide-mirror-settings.html

Using A Single Repository. You can force Maven to use a single repository by having it mirror all repository requests. The repository must contain all of the desired artifacts, or be able to proxy the requests to other repositories. This setting is most useful when using an internal company repository with the Maven Repository Manager to proxy external requests.

To achieve this, set mirrorOf to *.

<settings>
  ...
  <mirrors>
    <mirror>
      <id>internal-repository</id>
      <name>Maven Repository Manager running on repo.mycompany.com</name>
      <url>http://repo.mycompany.com/proxy</url>
      <mirrorOf>*</mirrorOf>
    </mirror>
  </mirrors>
  ...
</settings>

我不明白这一段。

不应该是这样的吗？

       <mirrorOf>*</mirrorOf>
     </mirror>
   </mirrors>
   ...
 </settings>

我的误会在哪里？

我的意思是， <mirror><id>internal-repository</id>...对我来说似乎是错误的。

镜像是指用作其他存储库的传递者/代理的存储库。
当使用像 Nexus、Artiafactory、Archiva 这样的存储库管理器时，你处理了一个本地企业存储库，它代表远程存储库。
所以不需要在你的 pom 或 setting.xml 中声明太多的仓库。仅使用一个将所有请求重定向到您拥有的存储库管理器的镜像就足够了。
这就是文档的含义。
