1.背景
编辑gitlab-ci流水线时，代码分析的job，maven使用sonar报错
- mvn clean verify sonar:sonar -Dsonar.login=30c55d3b8d3d2569431fb39f3c488c90643a6844
2.错误信息
[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.11.0.3922:sonar (default-cli) on project test: Unable to execute SonarScanner analysis: Fail to get bootstrap index from server: Host is unreachable (Host unreachable) -> [Help 1]

3.排查过程及解决
排查：
开始以为是scanner的版本问题，指定了scanner的版本，不行
后通过官方文档排查maven配置，发现sonar.host.url中的地址打错了
解决：修改setting.xml重新制作maven基础镜像，启动流水线运行成功
