1) 문제점
💡 문제점
- 해당 문제가 발생하는 환경은 Spring Boot 3.2.1 버전을 최초 생성하여 서버를 빌드하는 과정에서 Gradle에서 발생하는 문제로 아래와 같은 문제점이 발생하였습니다.
- 해당 문제점을 확인해보면 프로젝트의 구성이 java 8로 구성이 되어 있어서 java 17로 변경을 하는것을 권장한다는 문제였습니다.

The consumer was configured to find a library for use during runtime, compatible with Java 8, packaged as a jar, and its dependencies declared externally, as well as attribute 'org.gradle.plugin.api-version' with value '8.5' but:
- Variant 'apiElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.2.1 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 8
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '8.5')
- Variant 'javadocElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.2.1 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 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 '8.5')
- Variant 'mavenOptionalApiElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.2.1 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 8
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '8.5')
- Variant 'mavenOptionalRuntimeElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.2.1 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 8
- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '8.5')
- Variant 'runtimeElements' capability org.springframework.boot:spring-boot-gradle-plugin:3.2.1 declares a library for use during runtime, packaged as a jar, and its dependencies declared externally:

- Other compatible attribute:
- Doesn't say anything about org.gradle.plugin.api-version (required '8.5')

- 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 '8.5')
💡 실제로 공식사이트를 확인해 보면 Spring Boot 3.2.1 버전의 경우 최소 Java 버전을 17로 요구되고 있습니다.
