我试图升级cucumber以使用并行执行功能，结果导致报表门户出现问题。

在相容性矩阵中，它说：

cucumberjava和cucumberjUnit的版本- 4.0.0 - 4.2.6cucumber代理4.0.0的测试版本

我尝试了不同版本的Cucumber4.0。0, 4.2.3, 4.2.2, 4.2.6号cucumber制剂4.0。上面说

cucumber.runtime.CucumberExc0019：无法加载插件类：com.epam.reportportal.cucumber.Scenario记者。它不实现cucumber.api.插件

从cucumber 4和更高版本开始，定制插件需要实现cucumber中的一个。应用程序编程接口。事件或者cucumber。应用程序编程接口。事件ConcurrentEventListener接口。除此之外，还可以实现cucumber。应用程序编程接口。StepDefinitionReporter和/或Cumber。应用程序编程接口。摘要打印机。这些反过来又延伸了cucumber。应用程序编程接口。插件接口。

您正在使用的插件实现gherkin.formatter.For事和gherkin.formatter.记者界面

这方面已经存在一个问题：https://github.com/reportportal/agent-java-cucumber/issues/10以及在相同条件下给出的溶液-https://github.com/reportportal/agent-java-cucumber/issues/10#issuecomment-438434717.
