为什么SonarQube无法处理问题？

目前我们正在运行SonarQube 5.2，一些项目的代码分析失败。分析的日志文件以结尾

有人知道这里出了什么问题吗？

看看这篇文章。作为一种解决方法，或者如果您不想自己编译SonarQu，您可以执行以下更新（根据您的数据库修改语法）

---

我在使用Sonarqube6.0和安装了C#5.11插件的C#sources时遇到了同样的问题。修复程序解决了问题。如果您使用Oracle作为数据库，请使用

EMPTY\u CLOB（）

而不是

chr（10）

update FILE_SOURCES
set LINE_HASHES = chr(10)
where DATA_TYPE = 'SOURCE'
and LINE_HASHES is null
