Jenkins jacoco 插件空报告

Question

我有一个项目，我使用 Jacoco 来计算代码覆盖率。我在这里使用 Maven 配置：

http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/

对于 Jenkins，我运行 "mvn clean install test"。它在 /target/site/jacoco-ut/ 文件夹中生成报告。如果我打开 index.html 文件，我会看到：

但是当我在 jenkins 作业中打开 JaCoCo 覆盖率报告时，我看到了这个：

它说每个测试都覆盖了 0% 的代码。我不明白为什么我没有得到与 html 报告中相同的结果。

Answer 1

尝试在 Jenkins 插件中使用：

exec 文件的路径 = /.exec

我使用这个 pom :

<jacoco.it.execution.data.file>${project.build.directory}/coverage-reports/jacoco-it.exec</jacoco.it.execution.data.file>
    <jacoco.ut.execution.data.file>${project.build.directory}/coverage-reports/jacoco-ut.exec</jacoco.ut.execution.data.file>
    
    <plugin>
                    <groupId>org.jacoco</groupId>
                    <artifactId>jacoco-maven-plugin</artifactId>
                    <executions>
                        <execution>

Answer 2

我发现了一个与我的问题类似的 jenkins 问题：

https://issues.jenkins-ci.org/browse/JENKINS-28652

错误是jacoco版本问题。版本 0.7.5.201505241946 存在漏洞。我切换到版本 0.7.4.201502262128，现在可以使用了。

Answer 3

我有类似的问题，只需将 "jacoco-maven-plugin" 版本更新为 0.7.7.201606060606 并将 "maven-surefire-plugin" 版本更新为 2.19.1

即可解决

我希望这对你有用。
