SonarQube覆盖范围始终为0

Question

我有一个项目，使用SonarQube来分析我的代码。正如标题所示，尽管我有多个JUnit测试，但在SQ报告（在我的服务器上）中覆盖率指标总是显示为0。我目前运行以下命令

清理包部署声纳：声纳-Dsonar.projectKey=某物名-Dmaven.test.skip=true

在詹金斯建立我的项目时（詹金斯·马文项目）。

我有类似的问题前一段时间在不同的项目。我设法通过这篇文章解决了它。然而，这一次却无济于事。搜索了一下，找到了第1条和第2条（还有一些想法类似的）。两人都提出了一些好建议，但不幸的是，没有任何建议奏效。

我注意到我每次也会得到以下警告（不知道是什么原因造成的）

Cobertura report not found at /var/lib/jenkins/jobs/SomeProjectName/workspace/SomeFolderName/target/site/cobertura/coverage.xml

起初，我试图添加cobertura插件（如本文所建议的），但这只是删除了警告（报告中的覆盖率仍然为0）。我目前的理解是，它覆盖了Jacoco，但我没有找到原因或解决方案。

Answer 1

有几件事必须正确设置，以使您的测试覆盖率显示在SonarQube中。其中一些设置可能有默认值，但我尽量避免神奇的默认值，以确保我的设置彼此一致。

Surefire和Jacoco必须具有彼此一致的设置，SonarQube必须知道在哪里可以找到覆盖数据文件。

我将建议一些属性值供您使用。

sonar.coverage.jacoco.xmlReportPaths: ${basedir}/target/jacoco_report/jacoco.xml
jacoco.path: ${basedir}/target/jacoco_report

下面是你的jacoco插件的摘录：

<!-- Prepares the property pointing to the JaCoCo runtime agent which 
    is passed as VM argument when Maven the Surefire plugin is executed. -->
<execution>
    <id>pre-unit-test</id>
    <goals>
        <goal>prepare-agent</goal>
    </goals>
    <configuration>
        <propertyName>surefireArgLine</propertyName>
    </configuration>
</execution>
<!-- Ensures that the code coverage report for unit tests is created 
    after unit tests have been run. -->
<execution>
    <id>post-unit-test</id>
    <phase>test</phase>
    <goals>
        <goal>report</goal>
    </goals>
    <configuration>
        <!-- Sets the output directory for the code coverage report. -->
        <outputDirectory>${jacoco.path}</outputDirectory>
    </configuration>
</execution>

最后，这是Surefire插件的配置块：

<!-- Sets the VM argument line used when unit tests are run. -->
<argLine>${surefireArgLine}</argLine>

然而，在你的情况下，你有一个非常严重的问题，这将导致零覆盖率，即使你已经正确地完成了所有这些设置。感谢@Ian W指出这一点。

当我看到你写“尽管我有多个JUnit测试”时，我相信你的话，你实际上是在执行单元测试。命令行上有“-Dmaven.test.skip=true”，这将导致它无法执行任何单元测试。去掉那个。
