针对我的 SonarQube 4.1 实例在 sonar-example 项目上运行sonar-runner失败。在堆栈跟踪中，我注意到它给出了以下错误：
引起：java.sql.SQLException：用户'sonar'@'172.23.48.129'的访问被拒绝
该ip是我的本地机器IP。我的 SonarQube 服务器在另一个盒子上。
我的 sonar-runner.properties 和 sonar-project.properties 文件在任何地方都没有将 jdbc 设置为该 IP（或解析为该 IP 的主机名）。甚至下面的 INFO 级别日志也可以证明这一点。
奇怪的是，我可以在同一个示例项目上运行 sonar-runner，同时指向 SonarQube 4.5 的测试实例，并且分析成功运行。
它出错并给出以下输出：
