在远程服务器之前选择本地文件系统的链式Maven存储库

Question

我正在尝试链接maven，以便在远程服务器中查找依赖项之前从本地文件系统中获取它们。

settings.xml

<repository>
  <snapshots>
    <enabled>true</enabled>
  </snapshots>
  <releases>
    <enabled>true</enabled>
  </releases>
  <id>local</id>
  <name>libs-local-release</name>
  <url>file:///E:/project-folder/jars</url>
</repository>
<repository>
  <snapshots>
    <enabled>false</enabled>
  </snapshots>
  <id>central</id>
  <name>libs-release</name>
  <url>https://www.repositoryURL.com/libs-release</url>
</repository>

控制台用于mvn验证-U的结果

如您所见，Maven从我的文件系统和服务器下载依赖项，但是localRepository (%USERPROFILE%\.m2\repository)似乎被更新为服务器中的依赖项，而不是我的文件系统。

如何配置它，使本地jar文件(来自文件系统回购)比远程jar文件更受欢迎？

Answer 1

我不完全确定你想要实现什么，但我尽力了：

Maven有一个专用的本地存储库(您提到的那个存储库，C:\%USERPROFILE%\.m2\repository)。它总是先看那里。不需要为此配置任何东西。

快照依赖关系是一个例外，因为它们可以更改，因此Maven也会在远程存储库中查找它们(定期)。

从远程存储库下载的所有内容都存储在本地存储库中，因此在下一次尝试时，Maven不需要再次下载它。

如果您有您需要的jars，但是没有Maven存储库，那么根据jars的数量、用户的数量等等，您有几种处理这种情况的方法。
