我明白了 NoClassDefFoundError 在运行时（通过intellij或via运行测试 gradlew test )
这是我的简单测试（kotlin和kotest的新功能）

class AuthenticationValidatorServiceTest : StringSpec({
    val userRepository = mockk<UserRepository>()
    val userTypeRepository = mockk<UserTypeRepository>()
    val accessTokenRepository  = mockk<AccessTokenRepository>()
    lateinit var service: AuthenticationValidatorService

    beforeTest {
        service = AuthenticationValidatorService(userRepository, userTypeRepository, accessTokenRepository)
    }

    "Should throw ResourceNotFoundException" {
        shouldThrow<ResourceNotFoundException> {
            val userId = UUID.randomUUID()

            every { userRepository.findById(userId) } returns Optional.empty()
            service.validateUser(userId)
        }
    }
})

在我的gradle文件中是否有我错过的设置？我刚刚添加了这个

tasks.withType(Test) {
    useJUnitPlatform()
}

获取这些错误
