我正在尝试将一个我不太熟悉的项目的一部分提取到自己的应用程序中，同时也将其从Spring更改为Spring Boot，而我现在正在努力的步骤是引入代码覆盖率。 Jacoco转储目标失败，因为它拒绝连接。我对Maven还是很陌生，不知道如何设置Jacoco目标，以便在Tomcat仍在进行集成测试时执行它们。
我尝试在exec-maven插件的某处添加其他执行，但是我真的不知道那是我应该做的。我主要从现有项目复制配置，因此在下面的XML中，某些注释可能不再适用。但是他们可能会阐明在非Boot项目中如何使用Cargo插件进行测试。
我尝试删除一些多余的配置，但这是我的属性：
<maven.jacoco.plugin.version>0.8.2</maven.jacoco.plugin.version>
<jacoco.functional.test.exec.filename>${project.build.directory}/jacoco-it.exec</jacoco.functional.test.exec.filename>
<jacoco.unit.test.instruction.coverage.min>75</jacoco.unit.test.instruction.coverage.min>
<jacoco.func.test.instruction.coverage.min>75</jacoco.func.test.instruction.coverage.min>
</properties>
Spring Boot依赖项包括spring-boot-starter-actuator，spring-boot-starter-web，spring-boot-devtools，spring-boot-starter-test和：

<!-- Setting <phase> to 'initialize' ensures the 'prepare-agent-integration' goal
is run before cargo is started. The <phase> really should be the default phase
(pre-integration-test) not 'initialize', to run right before integration-test starts
and not at the beginning of the build. The problem is that Cargo is being started before
this plugin even though this plugin is declared first. It's because maven does not follow
