# file_name = xxx.git 正则匹配后 project_name = xxx

# 22 默认端口，如果 ssh 端口修改了 这里也要修改
git clone ssh://root@localhost:22/root/${project_name}.git
cd ${project_name}
# 构建
mvn clean
# 一般我是跳过单元测试
# mvn package -Dmaven.test.skip=true
mvn package
cd target
# 这里因为我的应用里面有 compose 文件夹
cp ${project_name}.jar ../compose/
cd ../compose/
docker-compose -f ${project_name}.yaml down
# 启动容器
docker-compose -f ${project_name}.yaml up -d
