专家雅各插件不生成覆盖率报告

Question

我使用sonarqube作为测试结果的输出，而maven和Jacoco用于测试测试用例。

Sonarqube版本是5.4 Maven版本是3.3.9 Jacoco版本0.7

这是我的pom.xml

我也在这里跟踪这个链接，但是对于我正在使用的文件，请在这里输入链接描述。

这就是我构建测试项目的方式

mvn clean test
mvn clean verify
mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent install
mvn sonar:sonar

buiild返回成功，但没有生成代码覆盖率我还通过去sonarqube检查了这一点localhost:9000/它显示0.00%的代码覆盖率，但单元测试都显示为成功“成功”。

你知道是什么导致了这个问题吗？而且，我对这一切还是新手。

从我的角度来看，设置看起来不错。

您已更改报告文件的默认名称。因此，我猜你也需要告诉声纳分析仪。

jacoco单元测试的默认名称是:< code > $ { project . build . directory }/jacoco . exec ，这也是sonar将尝试选取的名称。

您可以简单地设置一个属性来指示声纳分析器的位置:

<properties
    <sonar.jacoco.reportPath>${project.build.directory}/coverage-reports/jacoco-ut.exec</sonar.jacoco.reportPath>
    ...

请验证您的jacco文件是否存在并且不为空 - 如果sosonor迟会在正确配置位置后拾取它。
