Gradle 빌드 에러

Java 개발 프로젝트 세팅 중에 아래와 같은 에러가 발생했다.

A problem occurred configuring root project 'my_project'.
> Could not resolve all files for configuration ':classpath'.
   > Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.1.5.
     Required by:
         project : > org.springframework.boot:org.springframework.boot.gradle.plugin:3.1.5
      > No matching variant of org.springframework.boot:spring-boot-gradle-plugin:3.1.5 was found. The consumer was configured to find a library for use during runtime, compatible with Java 11, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.4' but:
          - Variant 'apiElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.1.5 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component for use during compile-time, compatible with Java 17 and the consumer needed a component for use during runtime, compatible with Java 11
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '8.4')
          - Variant 'javadocElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.1.5 declares a component for use during runtime, 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 11)
                  - Doesn't say anything about its elements (required them packaged as a jar)
                  - Doesn't say anything about org.gradle.plugin.api-version (required '8.4')
          - Variant 'mavenOptionalApiElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.1.5 declares a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component for use during compile-time, compatible with Java 17 and the consumer needed a component for use during runtime, compatible with Java 11
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '8.4')
          - Variant 'mavenOptionalRuntimeElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.1.5 declares a library for use during runtime, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component, compatible with Java 17 and the consumer needed a component, compatible with Java 11
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '8.4')
          - Variant 'runtimeElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.1.5 declares a library for use during runtime, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component, compatible with Java 17 and the consumer needed a component, compatible with Java 11
              - Other compatible attribute:
                  - Doesn't say anything about org.gradle.plugin.api-version (required '8.4')

해결

프로젝트에 사용된 Java 버전과 Gradle의 자바 버전이 달라서 발생한 에러로, IntelliJ의 경우 아래 경로에서 Gradle 버전을 프로젝트에 맞게 변경해주면 해결된다.

• File -> Settings -> Build -> Build Tool -> Gradle -> Gradle JVM
