maven jacoco 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 版本为 5.4 Maven 版本是 3.3.9 Jacoco 版本 0.7

这是我的pom.xml

我也在关注这个link here but for the files I am using the ones here enter link description here。

这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

构建 returns 成功但没有生成代码覆盖率我也通过声纳 localhost:9000/ 它显示 0.00% 代码覆盖率但单元测试都显示为成功"it is successful".

知道是什么导致了这个问题吗？而且我对这一切还很陌生。

从我的角度来看，设置看起来不错。

您已经更改了报告文件的默认名称。因此，我想您也需要将其告知声纳分析仪。

单元测试的 jacoco 默认值是：${project.build.directory}/jacoco.exec 这也是声纳将尝试获取的名称。

您可以简单地设置一个属性来指示声纳分析仪的位置：

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

请验证您的 jacco 文件是否存在且非空 - 如果是这样，一旦位置配置正确，声纳迟早会拾取它。
