Question

我正在尝试将maven链接到从本地文件系统获取依赖项，然后才能在远程服务器中查找它们。

的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>

mvn verify -U的控制台结果

正如您所看到的，Maven从我的文件系统和服务器下载依赖项，但localRepository (%USERPROFILE%\.m2\repository)似乎是使用服务器中的依赖项而不是我的文件系统进行更新。

如何配置它以使本地jar文件（来自filesystem repo）优先于远程jar文件？

Answer 1

我不完全确定你想要达到什么目标，但我尽我所能：

Maven有一个专用的本地存储库（你提到的那个，C:\%USERPROFILE%\.m2\repository）。它总是首先看起来。无需为此配置任何内容。

SNAPSHOT依赖项是一个例外，因为它们可以更改，因此Maven也可以（定期）在远程存储库中查找它们。

从远程存储库下载的所有内容都存储在本地存储库中，以便在下次尝试时，Maven不需要再次下载。

如果您有需要的罐子，但是没有Maven存储库，您可以通过多种方式处理这种情况，具体取决于罐子数量，用户数量等。
