使用maven时Spring Cloud Contract编译问题

Question

我最近按照他们的教程站点（ https://cloud.spring.io/spring-cloud-contract/#quick-start ）上的说明将 spring cloud contract 添加到我们的 spring 项目中。

我设法编写了合同，生成了存根，一切都按预期工作，但是在将一个干净的项目从我们的存储库中拉出来后，我在处理一个干净的项目时遇到了问题。 当我让mvn test运行时，我在生成的测试类中遇到编译错误，因为项目本身之前似乎没有构建，因此生产者站点上的合同测试的基类似乎还不存在。

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile (default-testCompile) on project kongo-shoppingcart-service: Compilation failure: Compilation failure: [ERROR] [...]/src/kongo-service-shoppingcart/kongo-shoppingcart-service/target/generated-test-sources/contracts/org/springframework/cloud/contract/verifier/tests/ContractVerifierTest.java:[7,64] package edu.hm.ba.kongo.shop.shoppingcart.service.test.contracts does not exist [ERROR] [...]/src/kongo-service-shoppingcart/kongo-shoppingcart-service/target/generated-test-sources/contracts/org/springframework/cloud/contract/verifier/tests/ContractVerifierTest.java:[14,43] cannot find symbol [ERROR] symbol: class ContractTestBase

我的项目 pom 看起来像这样：

但是当我手动构建模块并运行mvn test afterwords 时，一切都按预期工作。 我的 POM 的声明有什么问题吗？

Answer 1

出于某种原因，您的项目看不到您的基础测试类。 它不在类路径上。 你确定你把它放在正确的文件夹中吗？ 你必须显示你的文件夹结构。 你也可以查看https://github.com/spring-cloud-samples/spring-cloud-contract-samples并做类似的事情。 顺便说一句src/main/test看起来很糟糕，所以很可能你的项目设置是错误的。 我建议将合同和基类分别放在src/test/resources和src/test/java
