[Spring] Could not resolve all files for configuration ':classpath'. 에러

 

Spring initializr의 도움을 받아 인텔리제이에서 프로젝트 설정을 하다 

빌드 도중 아래와 같은 에러가 났다.

A problem occurred configuring root project 'order-service'.
> Could not resolve all files for configuration ':classpath'.
   > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.0.5.
     Required by:

확인해보니 Springboot 3.x 버전부터는 Gradle JVM이 17 이상이어야 했다.

필자는 springboot 3.0.5 버전을 받았는데, Gralde JVM 설정을 11로 설정해두어서 생긴 문제였다.

 

방법은 두가지

1. Springboot 버전을 다운그레이드 한다.

2. Gradle JVM 버전을 17이상으로 맞춰준다. 

 

나는 2번을 선택했다.

설정 방법은 Intelij 기준으로 

오른쪽 상단 File > Settings > Build, Execution, Deployment > Gradle > Gradle projects 에서

Gradle JVM을 17로 변경

 

재빌드 시 성공한 것을 확인할 수 있다.
