프로젝트 생성 단계, build.gradle 오픈시 오류

build.gradle를 오픈하자마자 다음과 같은 오류가 뜹니다ㅜㅜ

자바는 11버전 설치했고 강의 제일 처음, build.gradle부터 오픈하자마자 저런 오류가 났고 아무것도 안건들었습니다.

<오류코드>- 일부만 가져왔습니다.

A problem occurred configuring root project 'hello-spring'.

> 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

- 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:3.0.1 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 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 '7.6')

- Variant 'mavenOptionalApiElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional: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

- Other compatible attribute:

- Doesn't say anything about org.gradle.plugin.api-version (required '7.6')

- Variant 'mavenOptionalRuntimeElements' capability org.springframework.boot:spring-boot-gradle-plugin-maven-optional:3.0.1 declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
