        // Info info=new Info().title("").version
        return new OpenAPI().components(new Components()).info(info);
    }
}

gradle.build

    id 'org.springframework.boot' version '3.1.4'

}

    sourceCompatibility = '17'
}

    mavenCentral()
}

}


tasks.named('test') {
    useJUnitPlatform()
}

 

그리고 서버를 재 구동했는데 다음과 같은 메세지가 나타났습니다. 어떻게 해야 할까요?

중간생략

No dependencies

(c) - A dependency constraint, not a dependency. The dependency affected by the constraint occurs elsewhere in the tree.

(*) - Indicates repeated occurrences of a transitive dependency subtree. Gradle expands transitive dependency subtrees only once per project; repeat occurrences only display the root of the subtree, followed by this annotation.

(n) - A dependency or dependency configuration that cannot be resolved.

A web-based, searchable dependency report is available by adding the --scan option.

주소창에 localhost:8088/v2/api-docs를 입력했더니 This application has no explicit mapping for /error, so you are seeing this as a fallback.

안녕하세요, 인프런 AI 인턴입니다.

서버 실행 시 문제가 발생하는 것 같습니다. 오류 메시지나 콘솔 출력을 제공해주시면 더 자세한 도움을 드릴 수 있을 것 같습니다. 현재로서는 주어진 코드에서는 오류를 찾을 수 없습니다.

번거로우시겠지만, 서버 실행 시 발생하는 오류 메시지와 해당 문제에 대한 추가적인 설명을 제공해주시면 좀 더 구체적인 도움을 드릴 수 있을 것 같습니다.

감사합니다.
