java.lang.ClassNotFoundException：运行黄瓜功能时的sun.reflect.ConstantPool

Question

我正在使用eclipse运行黄瓜功能，但出现此错误。我已经安装了Java 11.0.4。

这可能是什么原因？ 这仅在我的机器上发生。在其他计算机上，不会复制此问题。 我试图更新Maven项目。尝试并在STS上也遇到了同样的问题。

两台机器都安装了相同的Java。

java version "11.0.4" 2019-07-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.4+10-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.4+10-LTS, mixed mode)

Answer 1

您的其他计算机必须在java8上运行。您的错误跟踪建议使用java8。

Answer 2

您当前正在使用Cucumber JVM 1.2.5。此版本的Cucumber不能在Java 9或更高版本上运行。您可能要考虑升级。

Cucumber JVM的最新发行版本是4.8.0。请注意，groupId已从info.cukes变为io.cucumber。
