I recently added spring cloud contract to our spring project following the instructions on their tutorial site here (https://cloud.spring.io/spring-cloud-contract/#quick-start).
I managed to write contracts, generate stubs and everything works as expected, but I have a problem when working with a clean project after pulling it off our repository. When I let mvn test run I get compilation errors in the generated test-class because it seems like the project itself didn't build before so the base-class for the contract tests on the producer site doesn't seem to exist yet.
[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:

But when I build the module by hand and run mvn test afterwords everything works as expected. Is there something wrong with the declaration of my POM?
For some reason your project can't see your base test class. It's not on the classpath. Are you sure you placed it in a proper folder? You'd have to show your folder structure. Also you can check out https://github.com/spring-cloud-samples/spring-cloud-contract-samples and do sth similar. BTW src/main/test looks really bad so most likely your project setup is wrong. I'd suggest keeping the contracts and the base classes under src/test/resources and src/test/java respectively
