스프링 부트 공식 홈페이지에 가면 아래와 같이 스프링 부트 프로젝트를 편하게 만들어주는 start.spring.io를 소개하고 있다.

원하는 옵션을 설정하고 Generate 버튼을 누르면 압축된 zip 파일을 다운로드 받는데 이를 프로젝트 폴더에 넣으면 된다. 문제는 내 경우 아래와 같은 에러가 발생했다.

A problem occurred configuring root project 'demo'.
> Could not resolve all files for configuration ':classpath'.
   > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.0.2.
     Required by:
         project : > org.springframework.boot:org.springframework.boot.gradle.plugin:3.0.2
      > No matching variant of org.springframework.boot:spring-boot-gradle-plugin:3.0.2 was found. The consumer was configured to find a runtime of a library compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '7.6' but:
          - Variant 'apiElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.0.2 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component compatible with Java 17 and the consumer needed a runtime of a component compatible with Java 8
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '7.6')
          - Variant 'javadocElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.0.2 declares a runtime of a component, and its dependencies declared externally:
              - Incompatible because this component declares documentation and the consumer needed a library
              - Other compatible attributes:
                  - Doesn't say anything about its target Java version (required compatibility with Java 8)
                  - Doesn't say anything about its elements (required them packaged as a jar)
                  - Doesn't say anything about org.gradle.plugin.api-version (required '7.6')

아래는 전체 에러의 일부를 캡쳐한 화면이다.
