更新

正在添加另一个maven日志。。。这是在测试用例运行之后

然后调用

mvn验证

同时检查maven的输出，它将提示您是否在测试中执行了jacoco。

我在应用程序中使用了powermock，但它与jacoco执行的在线检测不兼容。因此，使用离线插装并排除一些clousure类对我来说是有效的

我正在使用mvn clean verify install运行该作业，下面是我的pom的更改片段

运行

mvn测试

或

mvn验证

。您已经绑定了

jacoco:report

到测试阶段，它应该绑定到

verify

谢谢您的评论，但我有点困惑。。。请您详细说明一下。根据您的建议进行了更改，并从eclipse以干净的方式运行验证仍然存在相同的问题。我已经添加了maven日志供您参考。执行prepare-agent（预单元测试）。在测试执行之后，如果你发现了一些关于jacoco的信息，你能查看日志吗？添加了同一个maven运行的最后一部分。。。你能查一下吗
