可以看到在【ERROR】最后一行有报错：

Unknown host repo.maven.apache.org: 未知的名称或服务 ->

说明maven访问不到 repo.maven.apoache.org

原因分析：

机器的网络访问方式为，环境中的虚拟机通过代理访问安全PC，安全PC再通过huawei.proxy访问外网。此过程中存在访问失败。

解决方法：

沿着访问路径，可以通过curl或者浏览器逐一尝试访问maven的目的地址。发现各个机器均能够访问到目的地址，说明是maven自身的问题。

查询发现，maven自身也需要设置代理，代理设置位置为/maven/conf/settings.xml，在其中添加以下设置项即可：

<proxy>
      <active>true</active>
      <protocol>https</protocol>
      <host>192.144.3.79</host>
      <port>808</port>
      <nonProxyHosts>maven</nonProxyHosts>
    </proxy>

2、没有有效证书

可以看到最长一行[ERROR]里面有提示：

unable to find valid certification path to requested target

即没有有效证书来访问目标路径

解决方法：

解决方法一共有三种，第一种为生成并添加证书，第二种为改访问使用HTTP 的镜像，第三种为强行跳过检验

1.通过浏览器生成证书，并作为参数传给maven

Chrome 访问 https://repo.maven.apache.org/
F12 后在 Security -> View certificate -> 详细信息 -> 复制到文件(C)... 导出证书，格式选择 Base 64 编码 X.509 (.CER)
执行 keytool -import -file C:\mavenCert.cer -keystore C:\mavenKeystore
后续再执行 mvn 命令时需要带个参数 -Djavax.net.ssl.trustStore=C:\mavenKeystore，比如这样 mvn install -Djavax.net.ssl.trustStore=C:\mavenKeystore

2.更改中心库配置为HTTP协议能够访问的镜像

在settings.xml文件中添加中心库的配置。

<mirrors>
    <mirror> 
        <id>Central</id>   
        <url>http://repo1.maven.org/maven2</url>   
        <mirrorOf>central</mirrorOf>
    </mirror>    
</mirrors>

3. 强行跳过检验

可以依次尝试在命令后添加以下参数来取消验证

-Dmaven.wagon.http.ssl.insecure=true - enable use of relaxed SSL check for user generated certificates.
-Dmaven.wagon.http.ssl.allowall=true - enable match of the server's X.509 certificate with hostname. If disabled, a browser like check will be used.
-Dmaven.wagon.http.ssl.ignore.validity.dates=true - ignore issues with certificate dates.
