您好我想使用maven生成emma报告。当我尝试构建报告时，它会出现此错误。

这就是我向maven添加插件的方式。我只是为我的测试用例生成代码覆盖率报告。有没有人得到这个错误？

        <plugins>

Answer 1

您不应该使用emma插件，因为它集成了Emma which hasn't been updated in nearly a decade。即使它没有更新，它仍然继续工作多年。

最终，it was succeeded by EclEmma最终重新定位于JaCoCo（Java Code Coverage）。

现在，您需要jacoco plugin，它已经更新以跟上Java Generics的步伐，并且需要新的功能接口。
