如何在Maven .xml中定义存储库?

How can we define a repository in the pom.xml?

如何在pom.xml中定义存储库?

For example if dependency is not found in the repository defined in settings.xml then search for the dependency in the repository defined in pom.xml.

例如，如果没有在设置中定义的存储库中找到依赖项。然后，在pom.xml中定义的存储库中搜索依赖项。

An example on how this can be achieved would be great.

一个关于如何实现这一点的例子将是伟大的。

I am aware that placing repositories in the pom.xml is not a good option, but circumstances are pushing for this.

我知道在pom中放置储存库。xml不是一个好的选择，但是环境正在推动这一点。
