unit-testing - Jacoco 检查与 jacoco 报告中的不同覆盖率值

Question

我在我的项目中设置了 Jacoco 来执行 a) 检查代码覆盖率和 b) 生成覆盖率报告。生成的 HTML 报告显示了正确的覆盖率值，但 Jacoco 检查在构建过程结束时生成的警告消息显示了不同的错误值。我想知道我在这里做错了什么。

例如，我可以在生成的 HTML 报告中看到一个 util 类:

但是对于同一个类，我在构建完成时看到了这个:

这是我的 pom.xml 文件中的 jacoco-report 配置:

看起来您正在更改存储结果的位置:

<destFile>${sonar.jacoco.itReportPath}</destFile>

您还需要使用 <dataFile> 告诉检查插件在哪里可以找到数据文件。项目添加到您的规则配置中。
