根因分析

Maven 配置为使用需要认证的代理，但凭据缺失或不正确。

English

Maven is configured to use a proxy that requires authentication, but the credentials are missing or incorrect.

generic

解决方案

  1. 95% 成功率 Configure the proxy with correct credentials in settings.xml 
    <proxies><proxy><id>myproxy</id><username>user</username><password>pass</password><host>proxy.company.com</host><port>8080</port></proxy></proxies>
  2. 90% 成功率 Use environment variables for proxy authentication 
    export MAVEN_OPTS='-Dhttp.proxyHost=proxy.company.com -Dhttp.proxyPort=8080 -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass'

无效尝试

常见但无效的做法:

  1. Disabling the proxy in settings.xml 80% 失败

    If the network requires a proxy, disabling it will cause connection timeouts.

  2. Using incorrect credentials in settings.xml 90% 失败

    The proxy will reject the authentication, and the build will fail.
