Jenkins automatically releases jar packages

Introduction:

        Use Jenkins to automatically publish jar packages, here is a general shell release script

Generic script example:

#!/bin/bash
mvn clean install
# 定义变量,项目名称,文件地址,运行路径
PROJECT_NAME="adminxx"
JAR_FILE="/root/.jenkins/workspace/admin/target/$PROJECT_NAME.jar"
RUN_PATH="/home/java-jar"
# 停止旧的Jar包
if [ -f "$RUN_PATH/$PROJECT_NAME.jar" ]; then
  PID=$(ps -ef | grep $PROJECT_NAME.jar | grep -v grep | awk '{ print $2 }')
  if [ -n "$PID" ]; then
    echo "Stopping the application..."
    kill $PID
    sleep 5s
    echo "Application stopped."
  fi
fi
BACKUP_DIR="$RUN_PATH/backup"
# 创建备份目录
mkdir -p $BACKUP_DIR
# 备份旧的Jar包
if [ -f "$RUN_PATH/$PROJECT_NAME.jar" ]; then
  cp $RUN_PATH/$PROJECT_NAME.jar $BACKUP_DIR/${PROJECT_NAME}_$(date +%Y%m%d%H%M%S).jar
fi
# 删除旧的jar包
echo 'Delete old jar'
rm -rf $RUN_PATH/$PROJECT_NAME
# 拷贝新的Jar包到指定位置 
cp $JAR_FILE $RUN_PATH/
echo "Starting the application..."
# 启动应用程序
nohup java -jar $RUN_PATH/$PROJECT_NAME.jar --httpPort=80 > $RUN_PATH/logs/log.txt 2>&1 &
echo "Application started successfully."

Script analysis:

PROJECT_NAME: Define the project name
JAR_FILE: Packaged file path
RUN_PATH: Where to publish

Others hardly need to be changed, please adjust according to your personal situation
