Cucumber 测试用例未通过 Spring 启动 Jar 运行

Question

When I am running my Spring boot Application via Eclipse I am able to execute my cucumber test(Main.run(requestParamter, contextClassLoader)) case but when I am running via Spring boot Jar I'm getting below exception.

测试用例无法成功执行，异常是：

 io.cucumber.core.exception.CucumberException: The resource
 jar:file:/C:/386619/iplus-qeas-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/validation-api-2.0.1.Final.jar!/
 is located in a nested jar.\n\nThis typically happens when trying to
 run Cucumber inside a Spring Boot Executable Jar.\nCucumber currently
 doesn't support classpath scanning in nested jars.\nFeel free to send
 a pull request to make this possible!\n\nYou can avoid this error by
 unpacking your application before executing.

您正在从可执行 jar 文件中运行 Cucumber。 这意味着如果您打开 jar 文件，您将看到如下内容：

https://docs.spring.io/spring-boot/docs/current/reference/html/appendix-executable-jar-format.html

example.jar
 |
 +-META-INF
 |  +-MANIFEST.MF
 +-org
 |  +-springframework
 |     +-boot
 |        +-loader
 |           +-<spring boot loader classes>
 +-BOOT-INF
    +-classes
    |  +-mycompany
    |     +-project
    |        +-YourClasses.class
    +-lib
       +-dependency1.jar
       +-dependency2.jar

现在 cucumber 正在扫描整个 class 路径以查找胶水和特征文件。 这包括您在BOOT-INF/lib中的依赖项。 但是 Cucumber 无法打开这些。 然而，Cucumber 可以读取BOOT-INF/classes的内容，因为这很像普通的 jar 文件。

所以尝试通过--glue mycompany.project --features:classpath:mycompany/project 。 这样 Cucumber 只会扫描BOOT-INF/classes的内容。
