Nexus和Maven构建-Java 学习之路

我已经安装并配置了Nexus3 . 它位于代理后面，并且配置了HTTP部分 .

[第一评论后更新]

在我的settings.xml上

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <proxies/>
  <mirrors>
    <mirror>
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://nexus.company.it:8081/repository/maven-central/</url>
    </mirror>
  </mirrors> 
</settings>

当我尝试运行 mvn clean 时，我明白了

如果我浏览http://nexus.company.it:8081/repository/maven-central/

Nexus Repository Manager
 OSS 3.0.0-03    
 This maven2 proxy repository is not directly browseable at this URL.

如果我浏览http://nexus.company.it:8081/#browse/browse/components:maven-central，则存储库为空

有人可以帮我配置我的nexus作为maven中心的代理吗？

我找到了解决方案，即使“mvn clean -U”仍然无效 . 也许有人可以指出我正确的解决方案

1）插件不在中心位置 . 你应该maven-public将maven-central和maven-releases / snapshots分组

2）我在Nexus3中禁用了匿名登录 . 所以我需要创建一个用户来连接到Nexus3 . 这里有最终的settings.xml

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <profiles/>
  <proxies>
      <proxy>
        <active>true</active>
        <protocol>http</protocol>
        <host>XXX.XXX.XXX.XXX</host>
        <port>XXX</port>
        <nonProxyHosts>XXX.XXX.*|*localhost*|*.company.it*</nonProxyHosts>
      </proxy>
  </proxies>
  <servers>
     <server>
       <id>nexus</id>
       <username>XXXXXXXXXX</username>
       <password>XXXXXXXXXX</password>
     </server>
  </servers>
  <mirrors>
    <mirror>
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://nexus.company.it:8081/repository/maven-public/</url>
    </mirror>
  </mirrors> 
  <activeProfiles/>
</settings>

3）当您使用mvn时添加-U选项

里卡多
