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.

Test cases could not execute successfully and exception is:

 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.

Answer 1

You are running Cucumber from inside an executable jar file. This means that if you open the jar file you'll see something like this:

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

Right now cucumber is scanning the entire class path for glue and feature files. This includes your dependencies in BOOT-INF/lib . However Cucumber can't open these. Cucumber can however read the contents of BOOT-INF/classes because that is mostly like a normal jar file.

So try passing --glue mycompany.project --features:classpath:mycompany/project . This way Cucumber will only scan the contents of BOOT-INF/classes .
