java - Sonarqube 6.2 错误 - 无法完成符号执行 : reached limit of 16000 steps

Question

我使用 Sonarqube 6.2 和版本 4.4.0.8066 的 sonar java 插件，并在使用 JDK 1.8 编译的项目上遇到此错误:

[DEBUG] 22:09:01.566 Could not complete symbolic execution:

在运行 maven 构建过程的 sonar:sonar 步骤时，我是否遗漏了一些东西 clean install sonar:sonar ？

请帮助我摆脱困境。提前致谢..

Answer 1

这与符号执行引入的负面测试有关。

对于两条规则(关于空指针异常的 S2259 和关于条件始终为真或假的 S2583)，执行此测试。

本质上，在该方法中存在一个点，即 null/始终为 true 或 false 的所有可能性的总数迭代超过 6000。

您可以禁用这两个规则，或者重构该方法以使其中没有那么多 if/case 逻辑。

这对于 ( https://jira.sonarsource.com/browse/SONARJAVA-1406 ) 来说应该是非侵入性的，并且只能在 Debug模式下渲染，但是我可以确认它仍然会停止使用 Maven 插件进行读取。
