Java 설치는 이전에 작성한 아래의 링크를 보고 진행하면됨

=================================================================================================================
$ yum install git
=================================================================================================================
사용자 디렉토리에 바로 만들어도 되지만 관리하기쉽게 디렉토리를 하나 생성하고 클론을 했음
=================================================================================================================
$ mkdir camping
$ cd camping
$ git clone https://github.com/kkimsungchul/camping.git
=================================================================================================================
gradlew 파일은 바로 실행이 안됨, 권한설정을 해주어야 함
=================================================================================================================
$ chmod -R 755 camping/
=================================================================================================================
아래의 명령어로 빌드를 진행
-x check --parallel 옵션은 테스트를 하지 않겠다는 옵션
=================================================================================================================
$ ./gradlew build -x check --parallel
=================================================================================================================
※ 윈도우의 경우 아래의 명령어로 빌드, 혹시모르니 관리자 권한으로 실행
=================================================================================================================
gradlew.bat build
=================================================================================================================
빌드가 완료되면 해당프로젝트의 build/libs에 camping-0.0.1-SNAPSHOT.jar 파일이 생성되어 있음
ex)
/home/ec2-user/camping/camping/build/libs
※ 오류발생함, 권한문제로 하위 디렉토리까지 전부다 755룰 주면 해결됨
chmod -R 755 camping/
=================================================================================================================
$ ./gradlew build
> Task :test FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':test'.
> Unable to connect to the child process 'Gradle Test Executor 1'.
It is likely that the child process have crashed - please find the stack trace in the build log.
This exception might occur when the build machine is extremely loaded.
The connection attempt hit a timeout after 120.0 seconds (last known process state: STARTED, running: true).
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

$ cd /home/ec2-user/camping/camping/build/libs
$ nohup java -jar camping-0.0.1-SNAPSHOT.jar &
=================================================================================================================
오류 발생 1. 권한문제
※ 실행 안됨, 이거 권한문제였음, 권한 문제로 인해서 컴파일이 제대로 진행되지 안았었음
=================================================================================================================
$ cd /home/ec2-user/camping/camping/build/libs
$ nohup java –jar camping-0.0.1-SNAPSHOT.jar &
$ vim nohup.out
Error: Could not find or load main class –jar
=================================================================================================================
오류 발생 2. 하이픈 문제
아래의 명령어로 실행하면 잘됨.. 그냥 잘됨
=================================================================================================================
$ java -jar camping-0.0.1-SNAPSHOT.jar
=================================================================================================================
그래서 뭔가 이상해서 직접 타이핑을 해봄
=================================================================================================================
$ nohup java -jar camping-0.0.1-SNAPSHOT.jar &
=================================================================================================================
실행됨..
아래를 보면 복사한 코드의 경우 - 모양이 좀 이상한것을 알수 있음
이거 코드를 내가AWS에서 사용하고 history 에서 복사해온건데 이상하게 된거임
=================================================================================================================
$ nohup java –jar camping-0.0.1-SNAPSHOT.jar & -- 복사한 코드
$ nohup java -jar camping-0.0.1-SNAPSHOT.jar & -- 직접 타이핑한 코드
=================================================================================================================
파일 확인
=================================================================================================================
