Eclipse에서 Maven을 이용해 vert.x 2.0 프로젝트 생성, 디버깅, 빌드하기
개발환경
Eclipse IDE for Java EE Developers Luna packages
이클립스에서 Maven Project 생성
File -> New -> Other -> Maven Project
io.vertx를 선택
io.vertx가 없을 경우 io.vertx archetype 추가
프로젝트 생성
프로젝트를 생성하면, m2e 버그로, pom.xml에 maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.이라는 오류가 존재한다.
pom.xml에 <pluginManagement>를 추가해 주면 해결된다.
<build> <plugins> ... </plugins> </build> |
<build> <pluginManagement> <plugins> .... </plugins> </pluginManagement> </build> |
프로젝트 실행 및 디버깅 설정
Run Configurations -> Java Application -> R Click -> New
Main Tab
Main class : org.vertx.java.platform.impl.cli.Starter
Arguments Tab
Program arguments: run your.package.yourVerticle {-conf conf.json}
-conf 옵션은 conf.json 파일이 없다면, 생략 가능
VM arguments:
쓰레드 풀 사이즈를 조정하고 싶을 때
-Dvertx.pool.worker.size=1
-Dvertx.pool.eventloop.size=1
프로젝트 실행 및 디버깅한 화면
정상적으로 실행되어, 로그가 정상적으로 찍혀 있다.
브레이크 포인트에 걸린 디버깅 화면
프로젝트 빌드
Run As -> Maven install
JDK를 사용하라는 오류 발생

빌드 오류 해결
jre로 설정되어 있던 것을 jdk로 변경해 주면 해결된다.
Window -> Preferences -> Java -> Installed JREs -> Add -> jdk 폴더 추가
Execution Envionments -> JavaSE-1.7 -> jdk 선택
빌드를 다시 시도하여 성공하였다면,
다음과 같은 로그를 볼 수 있으며, target폴더에 jar파일이 생성된다.
