Gradle - Basic

Gradle - basic

• spring initializer에서 config을 설정하고 다운받습니다.
• 압축을 풀고 나서 해당 경로에서 다음 명령어를 실행해 주면 해당 경로에 필요한 plungin을 모두 설치해주고 build를 해줍니다.
• intelliJ의 경우는 그냥 해당 프로젝트의 폴더를 열면 알아서 다 처리해줍니다.

gradle build

• 폴더 내 build.gradle 파일을 확인해 보면, 대량 뭔지 보입니다.

plugins {
    id 'org.springframework.boot' version '2.4.2'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

• 아무튼 그냥 gradle tasks --all을 사용하면, 다음처럼 사용가능한 command들을 알 수 있습니다.

$ gradle tasks --all

• gradle bootrun을 사용해보면 다음처럼 Application이 돌아가는 것을 알 수 있죠 호호.
