Spring Boot 3.0.1

 

오류 메세지

A problem occurred configuring root project 'shop'.

> Could not resolve all files for configuration ':classpath'.

> Could not resolve org.springframework.boot:spring-boot-gradle-plugin:3.0.1.

Required by:

project : > org.springframework.boot:org.springframework.boot.gradle.plugin:3.0.1

> No matching variant of org.springframework.boot:spring-boot-gradle-plugin:3.0.1 was found. The consumer was configured to find a runtime of a library compatible with Java 11, 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:3.0.1 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 11
