在Maven中使用多个存储库 [英] Using multiple repositories in Maven

问题描述

我有一个使用内部存储库和中央存储库的项目.有没有一种方法可以配置settings.xml，以便我可以同时使用两者而不是一个?当我添加

I have a project that uses an internal repository and the central repository. Is there a way I can configure the settings.xml such that I can use both instead of just one? When I added

<mirrors>
    <mirror>
        <id>MY ID</id>
        <url>MY URL</url>
        <mirrorOf>*</mirrorOf>
    </mirror>
</mirrors>

在settings.xml中，我可以查看自己的内部存储库，但它会覆盖中央存储库.

in settings.xml, I can look into my own internal repository but it overrides the central repository.

我确定这是Maven新手经常遇到的问题.

I am sure this is a commonly encountered problem for people new to Maven.

推荐答案

有几种方法可以做到这一点.

There are a few of ways to do this.

最好的IMO是让本地存储库服务器充当Maven Central的代理. Nexus和Artifactory均可立即使用.如果您使用的是Apache或其他Web服务器，则应进行切换.

The best, IMO, is to have your local repository server act as a proxy for Maven Central. Both Nexus and Artifactory do this out of the box. If you're using Apache or another web server, you should switch.

您还可以更新设置，从镜像中排除目标服务器:

You can also update your settings exclude the target server from your mirror:

<mirrorOf>*,!MyOtherRepository</mirrorOf>

如果您有多个本地存储库服务器，则可以使用此方法，但是我认为您不能以这种方式排除 central :默认情况下，Maven在中央查找工件，并且您的服务器充当支架-为此.

This works if you have multiple local repository servers, but I don't think you can exclude central this way: by default, Maven looks for artifacts in central, and your server acts as a stand-in for it.

这将在您的POMS中保留显式存储库条目，这些条目引用了本地存储库.如果您的本地存储库只是为您的工件服务，那么这可能是第二件事(特别是如果您使用包含存储库规范的父POM).

Which leaves explicit repository entries in your POMS, which reference the local repository. If your local repository just serves your artifacts, this might be the second-simplest thing to do (especially if you use a parent POM that holds the repository specification).
