[2017-11-09] Configuring your clients and projects to use your Nexus repos_翻译within the open projects in your workspace, you -优快云博客

本文介绍如何在Maven项目中配置Nexus作为依赖下载源及发布仓库。首先需将认证信息添加到~/.m2/settings.xml文件中，并设置Nexus为中央仓库的镜像。接着，在pom.xml中配置仓库地址，以便从Nexus下载依赖，如需发布项目还需进一步配置发布仓库。

Put this in your ~/.m2/settings.xml file. This will configure the credentials to publish to your hosted repos, and will tell your mvn to use your repo as a mirror of central:

  <servers>
    <server>
      <id>nexus-snapshots</id>
      <username>admin</username>
      <password>admin123</password>
    </server>
    <server>
      <id>nexus-releases</id>
      <username>admin</username>
      <password>admin123</password>
    </server>
  </servers>

  <mirrors>
    <mirror>
      <id>central</id>
      <name>central</name>
      <url>http://your-host:8081/repository/maven-group/</url>
      <mirrorOf>*</mirrorOf>
    </mirror>
  </mirrors>

</settings>

And now configure your projects.

If you want only to download dependencies from Nexus, put this in the pom.xml:

<project ...>

  ...

  <repositories>
    <repository>
      <id>maven-group</id>
      <url>http://your-host:8081/repository/maven-group/</url>
    </repository>
  </repositories>
</project>

And if you want also to publish your project, add:

<project ...>

  ...

  <distributionManagement>
    <snapshotRepository>
      <id>nexus-snapshots</id>
      <url>http://your-host:8081/repository/maven-snapshots/</url>
    </snapshotRepository>
    <repository>
      <id>nexus-releases</id>
      <url>http://your-host:8081/repository/maven-releases/</url>
    </repository>
  </distributionManagement>
</project>
