我自己编写了一个简单的 spring boot 项目,使用 maven 打包后,用 jacoco 来统计覆盖率
java 版本:Java 18.0.1.1
jacoco 版本:0.8.8
执行了如下命令

java -javaagent:jacocoagent.jar=includes=*,output=tcpserver,port=6300,address=localhost,append=true -jar FirstDemo-0.0.1-SNAPSHOT.jar 

java -jar jacococli.jar dump --address localhost --port 6300 --destfile ./jacoco-demo.exec

java -jar jacococli.jar report ./jacoco-demo.exec 
--classfiles C:\Users\PC\IdeaProjects\FirstDemo\target\  
--sourcefiles C:\Users\PC\IdeaProjects\FirstDemo\src\main\java --html report --xml report.xml

前面两个都执行成功,最后一个命令执行报错

我的 maven 配置如下
