sonar-maven-plugin:3.1.1:sonar 升级到 SonarQube 6.0 后分析错误

Question

我们刚升级到SQ 6.0，现在一些项目用maven分析时出现如下错误：

跟踪的最后部分是

当我们使用 org.codehaus.mojo:sonar-maven-plugin:2.7.1:sonar 时也会发生这种情况，并且似乎是特定于项目的，有些项目有效，有些则无效。

谁能提示这里出了什么问题？

Answer 1

感谢@teryk-sonarsource-team，只是将其作为答案：

1. 删除 SonarQube 安装中的目录 data/es。
2. 重新启动 SonarQube。

它将重新计算所有 ES 索引。

这解决了我在 SonarQube 5.6.3 中的问题。
