无法在sonarqube中获得测试覆盖率

Question

[在这里输入图像描述][1][在这里输入图像描述][2]我知道很多人都有类似的问题。我展示了很多答案，尝试了在声纳网站上给出的示例代码。那个样品工作得很好。我还显示以下链接

maven 3.0.5

请帮我解决这个问题。

我真的觉得这是jacoco或Sonarqube的bug。可能它不兼容Java8之类的东西。我几乎什么都试过了。sonar java插件2.5.1不推荐使用许多东西。请帮帮我，我迫切需要解决方案

Answer 1

刚刚试了一下，示例项目工作得很完美。请确保您做到以下几点：

git clone https://github.com/SonarSource/sonar-examples.git
cd projects/languages/java/code-coverage/combined ut-it/combined-ut-it-multimodule-maven-jacoco
mvn clean package
mvn sonar:sonar

另外--不确定这是否相关，但您使用的是SQ Java插件的一个非常旧的版本(2.5.1)。我只能建议你把它更新到最新版本。
