Maven部署至Azure DevOps Artifact遇连接重置失败求助

尝试通过安全连接将Maven项目部署至Azure DevOps Artifact时，出现BUILD FAILURE错误，核心报错为java.net.SocketException: Connection reset。完整mvn deploy日志如下：

已尝试配置Maven settings和pom文件，但问题仍未解决，请问该如何处理？

• 检查网络与代理配置

  1. 直接测试Azure DevOps Artifact仓库URL的连通性：执行curl -v https://.../_packaging/.../maven/v1查看是否能正常建立连接，排查是否存在代理拦截、防火墙阻断的情况。
  2. 确认Maven settings.xml中的代理配置：如果使用代理，确保代理地址、端口、认证信息正确，且代理允许访问Azure DevOps域名；若无需代理，直接删除settings.xml中的代理节点。

• 验证Azure DevOps认证信息

  1. 确认settings.xml中server节点的username和PAT令牌有效性：Azure DevOps需使用个人访问令牌（PAT）作为密码，令牌需具备**Packaging (Read & Write)**权限，且未过期。
  2. 检查server节点的id是否与pom.xml中distributionManagement里repository的id完全一致（大小写敏感）。

• 调整Maven传输配置

  1. 增加Maven超时时间：在pom.xml中为maven-deploy-plugin添加超时参数：

     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-deploy-plugin</artifactId>
       <version>3.1.1</version>
       <configuration>
         <timeout>60000</timeout> <!-- 设置60秒超时 -->
       </configuration>
     </plugin>
     

  2. 禁用HTTP/2协议：在环境变量中设置MAVEN_OPTS="-Dhttp.client.version=HTTP/1.1"，再重新执行mvn deploy。

• 检查Azure DevOps仓库状态
  登录Azure DevOps门户，确认目标Artifact仓库是否正常运行，是否设置了IP白名单限制，若有则将本地机器IP加入允许列表。

• 清理Maven本地缓存
  删除本地仓库中对应项目的元数据文件（路径一般为~/.m2/repository/demo/maven-demo/0.1-SNAPSHOT/maven-metadata*.xml），然后执行mvn clean deploy -U强制更新元数据。
