如何使Maven单元测试代码覆盖工作

Question

在Eclipse中，我使用EcLEmma来查看单元测试代码的覆盖范围。哪个工作正常。因此，我尝试使用Maven的JaCoCo插件来查看与Maven构建的Surefire相同的报告，甚至更好，具有特定的配置文件，或在站点周期中。没有成功。这里所有建议的解决方案都不适用于我。

获得单元测试代码覆盖率报告的最佳方法是什么（使用surefire）？

[编辑]更具体地说为什么jacoco对我失败了......因为我总是因为缺少执行数据而执行跳过JaCoCo

来自物业中的pom

    <jacoco.it.execution.data.file>${project.build.directory}/coverage-reports/jacoco-it.exec</jacoco.it.execution.data.file>
    <jacoco.ut.execution.data.file>${project.build.directory}/coverage-reports/jacoco-ut.exec</jacoco.ut.execution.data.file>

是我的最后一次尝试，但是pom变得越来越大，没有任何结果
