我是 SonarQube 的新手，并且遇到连接超时错误，阻止 sonar-runner 将小型应用程序发布到 sonarqube。
版本：
- SonarQube 亚军 2.4
- Java 1.7.0_45 甲骨文公司（64 位）
- Linux 3.5.0-42-通用 amd64
令人困惑的部分是，在托管 sonarqube 的 Windows 机器上执行 sonar-runner 时，这可以正常工作。我已将端口默认端口从 9000 更改为并测试了两个连接的有效性。这并没有解决问题。
仅当尝试从存储源代码的虚拟机上的命令行手动运行 sonar-runner 时才会发生错误。我还通过 sonar-runner.bat 文件中的 SONAR_RUNNER_OPTS 增加了堆大小中允许的内存。
请告知或让我知道需要哪些其他信息。
