Java 杰科科考试失败了。覆盖率始终为0

Jacoco插件丢失JUnit测试，报告始终为0%，但测试存在。我认为问题在于我的

pom.xml

。帮我找出错误

也许它与

checkstyle

插件冲突

使用Jacoco设置的部件：

没有执行测试，因此没有覆盖范围

你有

这可能是由于您的

执行

mvn测试

因为依赖项中有

junitjupiter

， 但是没有

junit-vintage引擎

（请参见

mvn-dependency:tree

）的输出， 而您的测试是使用JUnit4编写的

在以下删除了junit vintage engine的排除后

本地测试的结果相同。我被困在本地测试配置步骤中。我删除了
