Jacoco 插件丢失了 JUnit 测试，报告总是 0% 但测试存在。我认为问题出在我的 pom.xml 上。帮我找出错误。
也许它与checkstyle 插件有冲突？
部分 Jacoco 设置:

最佳答案
没有执行测试，所以没有覆盖。
在build log你有
[INFO] Tests are skipped.
这可能是由于您的 .github/workflows/build.yml 中的 -DskipTests
run: mvn -B clean package -DskipTests
执行mvn test产生
[INFO] --- maven-surefire-plugin:2.22.2:test (default-test) @ bridge ---
[INFO]
[INFO] -------------------------------------------------------
[INFO] T E S T S
[INFO] -------------------------------------------------------
[INFO]
[INFO] Results:
[INFO]
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0
因为你在依赖项中有 junit-jupiter，
但是没有junit-vintage-engine(见mvn dependency:tree的输出)，
而您的测试是使用 JUnit 4 编写的。
在以下删除 junit-vintage-engine 排除之后
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
+ <!--
<exclusions>
<exclusion>
<groupId>org.junit.vintage</groupId>
<artifactId>junit-vintage-engine</artifactId>
</exclusion>
</exclusions>
+ -->
执行mvn test产生
[INFO] Tests run: 47, Failures: 0, Errors: 0, Skipped: 0

关于java - Jacoco 输掉了测试。覆盖率始终为 0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64590837/
