java - 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，而使用 maven 和 jacoco 来测试测试用例。

Sonarqube 版本是 5.4Maven 版本是 3.3.9Jacoco 版本 0.7

这是我的 pom.xml

我也在关注这个link here但对于我在这里使用的文件 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

构建成功返回，但没有生成代码覆盖率我还通过转到 sonarqube localhost:9000/进行了检查，它显示 0.00% 的代码覆盖率，但单元测试都显示为成功“成功”。

知道是什么导致了这个问题吗？而且我对这一切还是陌生的。

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，我猜想您也需要将其告知 Sonar 分析仪。

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

您可以简单地设置一个属性来指示 Sonar 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， Sonar 迟早会拾取它。
