spring-cloud-contract - 为什么使用 Spring Cloud Contract 在 Gradle、Kotlin、Spring Boot 应用程序中compileTestGroovy 失败

Question

Spring Cloud Contract Gradle 插件 (2.0.2.RELEASE)

我的 Kotlin 项目，一个 Spring Boot 2.0.5.RELEASE 应用程序，在 src/test/下有一个 Groovy 合约文件resources/contracts 和 Base 测试类 com.mycompany.practice.base. Producer.PracticeMessagingBase 成功生成了 ContractVerifierTest 并且打开该文件表明 IntelliJ 很高兴使用该文件，但在 compileTestGroovy

上运行 ./gradlew clean build 失败

:compileTestGroovy (Thread[Task worker for ':',5,main]) completed. Took 1.807 secs.

我可能做错了什么吗？

如果您查看失败的任务 - 它是 compileTestGroovy。由于 Groovy 可以编译 java，因此它会尝试编译基类。然而，它无法真正编译基类，因为它无法访问 Kotlin 的基类。只需在 build.gradle 中设置 compileTestGroovy.enabled = false ，一切都会正常工作
