Question

Using Spring Cloud Contract 2.1.3.RELEASE with spring-boot 2.1.1.RELEASE, I have added the dependency and plugin per explained in the guide:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-contract-verifier</artifactId>
<version>${spring-cloud-contract.version}</version>
<scope>test</scope>
</dependency>
and
<plugin>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-contract-maven-plugin</artifactId>
<version>${spring-cloud-contract.version}</version>
<extensions>true</extensions>
</plugin>
I have also added under: $rootDir/src/test/resources/contracts:
Groovy file:
package contracts
import org.springframework.cloud.contract.spec.Contract
Contract.make {
name("contract_updateNodeV4")
request {
method 'PUT'
url '/v4/nodes'
headers {
header 'Content-Type': 'application/vnd.org.springframework.cloud.contract.verifier.twitter-places-analyzer.v1+json'
}
body(file("updateNodeV4_request.json"))
}
response {
status OK()
body(file("updateNodeV4_response.json"))
}
}
And corresponding updateNodeV4_request.json and updateNodeV4_response.json (omitting their contents since these are large) valid JSON files.
When running mvn clean install I expected generated tests to be created (and fail for now) per the guide.
Instead I am getting the following error:
[ERROR] Failed to execute goal org.springframework.cloud:spring-cloud-contract-maven-plugin:1.0.0.RELEASE:generateStubs (default-generateStubs) on project xxx: Stubs could not be found: [C:\Users\xxx\git\xxx\target\stubs] .

Answer 1

Most likely your contacts are not under the module's src/test/resources/contracts but under the root module's folder. If that's the case you need to tell the plugin that by seeing the contracts dir plugin property

Answer 2

I solved it by moving the plugin:
<plugin>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-contract-maven-plugin</artifactId>
<version>${spring-cloud-contract.version}</version>
<extensions>true</extensions>
</plugin>
From the root pom.xml to the specific module's pom.xml in which I have created the contracts in. Now it works as expected.
