Gradle Spring Cloud Stream project does not build because of test dependency

Question

When I try to build a Gradle Spring Boot project with Spring Cloud Stream I receive the following error:

Execution failed for task ':compileTestJava'.
> Could not resolve all files for configuration ':testCompileClasspath'.
   > Could not find org.springframework.cloud:spring-cloud-stream:test-binder.
     Required by:
         project :
   > Could not find org.springframework.cloud:spring-cloud-stream:test-binder.
     Required by:
         project :
   > Could not find org.springframework.cloud:spring-cloud-stream:test-binder.
     Required by:
         project : > org.springframework.cloud:spring-cloud-stream-binder-kafka-streams:3.0.9.RELEASE > org.springframework.cloud:spring-cloud-stream-binder-kafka-core:3.0.9.RELEASE

The project works fine if I remove the following dependency:

testImplementation 'org.springframework.cloud:spring-cloud-stream:test-binder@test-jar'

The project was generated using Spring initilizr with this configuration.

What can I change so the project builds successfully?

Answer 1

Change

testImplementation 'org.springframework.cloud:spring-cloud-stream:test-binder@test-jar'

to

testImplementation("org.springframework.cloud:spring-cloud-stream") {
        artifact {
            name = "spring-cloud-stream"
            extension = "jar"
            type ="test-jar"
            classifier = "test-binder"
        }
}

Currently, Spring Initializr generates Gradle projects with this error and the problem is documented in #1159 and #591.
