4편 JAVA spring boot study - java 코드 파일 build하기

우선 해당 폴더로 build하고 싶은 gradlew build파일이 있는 프로젝트 파일로 이동을 합니다.
각자 프로젝트 path가 다를것이기때문에 이부분은 생략하겠습니다.

해당 프로젝트에 gradle 파일이 있는지 확인합니다.

	./gradlew build

build가 성공적으로 되었다면 아래와 같은 메시지가 나옵니다.

	BUILD SUCCESSFUL in 1s
	7 actionable tasks: 7 up-to-date

	cd build
    cd libs

	ls

를 입력하면

	hello-spring-0.0.1-SNAPSHOT-plain.jar 
	hello-spring-0.0.1-SNAPSHOT.jar

와 같이 나오게 됩니다. 저는 빌드를 두번 했기때문에 두개가 나왔습니다.
해당 빌드된 파일중에 어떤것 실행할지 결정합니다.

java -jar hello-spring-0.0.1-SNAPSHOT.jar

아래와 같이 성공적으로 실행되는 것을 볼 수 있습니다.
저는 8080에 인텔리제이 상에서 이미 실행한 애플리케이션이 있기에 port에러가 있었지만 8080 포트를 사용하는 애플리케이션이 없었다면 성공적으로 실행될 것입니다!
