spock - DebuggingClassWriter 重写 final方法访问

Question

我有一个 grails 3 项目，我必须在其中编写一个常规的 Spring MVC @RestfulController(出于 block json 响应的原因)。无论如何，我尝试为简单的 Controller 操作编写一个简单的 Spock 单元测试。它们在 IDEA 中运行良好，但在命令行中它们失败，并出现与我所阅读的 asm/cglib 相关的奇怪错误。有人知道我该如何解决这个问题吗？

    def cleanup() {

        given:
        print "1"

        BasicSearchCommand basicSearchCommand = new BasicSearchCommand()
        PageRequest pageRequest = new PageRequest(0, 20)

        when: "The basic search action is executed with a BasicSearchCommand"

        Page page = searchController.basic(basicSearchCommand, pageRequest)

        then: "The correct search service was called with the appropriate arguments and returned expected results"

        1 * searchService.basic(basicSearchCommand, pageRequest) >> expectedPage
        page == expectedPage

    }

    def "Test the advanced search action returns a page of results"() {

        given:
        print "2"
        Page expectedPage = new PageImpl<CourseGuide>([new CourseGuide()])
        AdvancedSearchCommand advancedSearchCommand = new AdvancedSearchCommand()
        PageRequest pageRequest = new PageRequest(0, 20)

        Page page = searchController.advanced(advancedSearchCommand, pageRequest)

        then: "The correct search service was called with the appropriate arguments and returned expected results"

        1 * searchService.advanced(advancedSearchCommand, pageRequest) >> expectedPage
        page == expectedPage

    }

我刚刚遇到了类似的问题。

cglib:cglib-nodep:2.2.2 库似乎需要在编译时可用。它由 org.grails:grails-plugin-testing 插件引入。

我能够通过两种方式解决它；两者都涉及 build.gradle 中的 dependencies {...} block :

1) 添加compile 'cglib:cglib-nodep:2.2.2'

或者

2) 将 testCompile "org.grails:grails-plugin-testing" 更改为 compile "org.grails:grails-plugin-testing"

希望对您有所帮助。
