jacoco-ut.exec文件是在target / coverage-reports / jacoco-ut.exec中创建的，但没有可见的站点/目录。
以下是Jacoco配置：

更新：我运行了以下命令：mvn jacoco：report -X 它说了一些有趣的事情：

当我创建一个jacoco-ut.exec文件时，它正在查找jacoco.exec文件。
自文件创建以来，这有点令人惊讶：
$ ll target/coverage-reports/jacoco-ut.exec
-rw-rw-r-- 1 stephane 2.9M Mar 29 09:47 target/coverage-reports/jacoco-ut.exec
我想我需要在某处的报告配置中指定该文件名。
更新：在Jacoco配置中移动上面的destFile和dataFile配置后，问题得以解决，报告在站点/目录中生成。

虽然插件是在plugins元素中定义的，而不是在pluginManagement元素中，但为了获取报告，我仍然需要执行命令：
mvn jacoco:report
我希望在运行命令时生成报告：
mvn clean install
答案 0 :(得分：0)
使用此配置，您在使用mvn clean install生成网站时不会遇到任何问题。
在站点文件夹中，将有两个不同的文件夹：jacoco包含单元测试的报告，jacoco-it包含集成测试的报告。
JaCoco配置
配置Jacoco公开配置变量以集成单元测试（jacoco.argLine）和集成测试（jacoco.it.argLine），并生成包含集成测试报告的文件夹（jacoco-it）：< / p>

看看<argLine>${jacoco.it.argLine}</argLine>。此占位符将替换为JaCoco插件指定的所有参数。它将包含将JaCoco与集成测试集成所需的配置变量。

再次，看看<argLine>${jacoco.argLine}</argLine>。它将包含将JaCoco与单元测试集成所需的配置变量。
