Maven 자바 프로젝트 생성

mvn archetype:generate -DgroupId=com.newlecture -DartifactId=javaprj -DarchetypeArtifactId=maven-archetype-quickstart

-DarchetypeArtifactId=maven-archetype-quickstart
다른 사람이 만든 maven-archetype-quickstart 라는 프로젝트 구조를 기본으로

-DartifactId=javaprj
javaprj 라는 새로운 프로젝트로 생성

-DgroupId=com.newlecture
여러 개의 프로젝트를 만들 경우 충돌하지 않도록 그룹ID를 지정

pom.xml이 있는 곳이 root dir
해당 디렉토리로 이동하여 mvn compile하면 해당 소스코드를 javac로 컴파일 가능
