我遵循here给出的有关如何将SonarQube与基于Ant的项目集成的说明。但是当我到达必须调用ant sonar的点时，它就会失败。
在达到这一点之前，我已经确认Sonar已启动并正在运行，并且可以访问以下网址并显示默认的“欢迎使用SonarQube信息中心”页面：
http://localhost:9000
通过做tail -f logs/sonar.log我在某个时刻看到以下内容似乎与问题重合：
$ tail -f sonarqube-4.5.4/logs/sonar.log

这是根本原因（取自你的堆栈跟踪）：
Caused by: org.sonar.api.utils.HttpDownloader$HttpException: Fail to download [http://localhost:9000/api/server]. Response code: 500
HTTP 500代码表示您的Sonar服务器出现问题。它是否按预期在以下URL上运行？
http://localhost:9000
如果是这样，我建议接下来检查服务器端日志文件以获取错误消息。
