SonarQube扫描仪可以'；无法连接到服务器

我遇到了sonar scanner cli无法连接到SonarQube服务器的问题。扫描从docker容器中运行。Docker通过代理连接到SonarQube服务器，所以我认为这是问题所在，但我尝试设置代理环境变量，并将代理参数传递给扫描仪。那没用。此外，其他二进制文件（如yum或gradle）也可以从同一容器连接到外部repo，而不会出现问题

SonarQube服务器版本：6.7.0.33306

我认为你应该验证你的防火墙。在大多数系统中，端口9000未打开，这是常见的故障源。

检查settings.xml和pom.xml中是否正确配置了sonar服务器
