java - Maven 构建因 Spring-cloud-contract-verifier 而失败

Question

我在使用以下 pom.xml 构建 spring-cloud-contract-verifier 时遇到问题:

<parent>

我尝试全新安装 项目，以便让spring-cloud-contract 生成我的测试类。 BaseClass 如下:

    @RunWith(SpringRunner.class)
    @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.MOCK, classes = PricingServiceApplication.class)
    @DirtiesContext
    public class BaseClass {

    @Autowired
    private RateChartController rateChartController;

    @Before
    public void setup() {
        StandaloneMockMvcBuilder standaloneMockMvcBuilder = MockMvcBuilders
            .standaloneSetup(rateChartController);
        RestAssuredMockMvc.standaloneSetup(standaloneMockMvcBuilder);
    }
}

我偶然发现的异常如下:

如果您能帮我解决这个问题，我将不胜感激。

看起来您在默认路径 (src/test/resources/contracts) 下没有契约(Contract)，这导致不复制然后到目标导致异常。
