这篇文章memo一下sonar-scanner和SonarQube版本不一致时导致的问题。

现象

使用sonar-scanner进行angular的typescript代码的质量扫描，执行时间非常之长，而且非常容易使得SonarQube服务挂掉。在等待的时间会提示如下的信息

...
WARN: [JOURNAL_FLUSHER] WARNING Journal flush operation took...
WARN: [JOURNAL_FLUSHER] WARNING Journal flush operation took...
...

再现环境

使用如下环境：

• Sonar-Scanner： 4.2 （使用JDK 8，不实用sonar-scanner内嵌的JRE）
• SonarQube： LTS 6.7.1

原因与对应方法

使用JDK 8 + Sonar-Scanner 3.2版本，连接SonarQube LTS 6.7.1多次试验，发现不会出现任何问题。基本上应该是版本兼容性问题。

注：此问题为并不是百分之百再现，另外，使用Sonar-Scanner 3.2 连接SonarQube LTS 6.7.1版本和SonarQube LTS 7.9.1版本并没有发现会使得SonarQube服务异常中断的问题。
