[Jenkins/shell] 빌드된 jar 실행하기.sh

Jenkins에서 프로젝트 빌드를 진행한 후 스프링 부트 서버를 실행해야한다.

이때 빌드에 성공하면 " /var/lib/jenkins/workspace/<Project>/build/libs/ " 에 SNAPSHOT  jar 파일이 생성되는데

jar 파일을 실행하려면 java -jar 명령어를 사용한다.

 

 

아래는 Jenkins 플러그인 post build task에서 빌드된 jar를 실행하기 위한 shell script이다.

#!/bin/bash

JAR_NAME=<JAR 파일명>

if [ -z "`ps -eaf | grep $JAR_NAME | grep -v grep`" ]; then
  echo "not found $JAR_NAME"
else

  ps -eaf | grep $JAR_NAME | grep -v grep | awk '{print $2}' |
  while read PID
  do
    echo "Killing $PID ..."
    kill -9 $PID
    echo "$PID is shutdown!"
  done
fi

nohup java -jar "/var/lib/jenkins/workspace/<프로젝트명>/build/libs/$JAR_NAME" &
