Nexus代理repo.maven.apache.org无法正常工作

Question

我在Nexus中为Apache库创建一个新闻代理Maven 2：

然后我将pom.xml更改如下：

<repositories>
    <repository>
        <id>maven-public</id>
        <url>http://nexus.unc.nc/repository/maven-public/</url>
    </repository>
    <repository>
        <id>maven-releases</id>
        <url>http://nexus.unc.nc/repository/maven-releases/</url>
    </repository>
    <repository>
        <id>maven-apache</id>
        <url>http://nexus.unc.nc/repository/maven-apache/</url>
    </repository>
</repositories>

但是它仍然从互联网上下载apache lib：

[INFO] --- maven-install-plugin:2.5.2:install (default-install) @ importparcoursup ---
Downloading from central: https://repo.maven.apache.org/maven2/junit/junit/3.8.1/junit-3.8.1.pom
Downloaded from central: https://repo.maven.apache.org/maven2/junit/junit/3.8.1/junit-3.8.1.pom (998 B at 2.0 kB/s)

而其他lib则来自关联：

Downloading from maven-public: http://nexus.unc.nc/repository/maven-public/org/springframework/boot/spring-boot-starter-mail/2.0.6.RELEASE/spring-boot-starter-mail-2.0.6.RELEASE.pom

有人可以在这里帮助我吗？

Answer 1

这是因为central存储库的配置是从super POM继承的。您可以尝试覆盖它，如下所示：

<repository>
    <id>central</id>
    <url>http://nexus.unc.nc/repository/maven-apache/</url>
</repository>

或者-这是推荐的解决方案-在settings.xml中放入mirror definition：

<settings>
  ...
  <mirrors>
    <mirror>
      <id>company-central</id>
      <name>Company Central</name>
      <url>http://nexus.unc.nc/repository/maven-apache/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>
  ...
</settings>
