maven打包

执行 mvn clean package -Pprofile

依次执行：

maven-clean-plugin:3.0.0:clean

删除target目录和本地logs目录

maven-resources-plugin:3.0.2:resources

拷贝src/main/resources下的资源文件到target/classes目录下

maven-compiler-plugin:3.7.0:compile

编译src/main/java 类文件到target/classes目录下

maven-jar-plugin:3.1.0:jar

构建thin jar包到target目录下

maven-dependency-plugin:3.0.1:copy-dependencies

拷贝依赖jar包到release/lib目录下

maven-resources-plugin:3.0.2:copy-resources

拷贝自定义资源文件到release目录下

打包后的项目和相关资源文件依赖jar包都放在release目录下：

发布

rysnc脚本：其中test_env是在~/.ssh/config下定义的机器别名

touch ./release/application.pid
chmod a+x ./release/bin/*.sh
release_dir=/home/server-demo/release/
zip -r server-demo-release.zip ./release/
rsync -zvrP --delete --rsync-path="mkdir -p $release_dir && rm -rf $release_dir/*.jar && rsync"  ./server-demo-release.zip test_env:$release_dir

此时，release目录包含了要运行的java程序的所有组件，将此目录压缩成zip包，使用rsync脚本上传到相应的服务器，启动即可。

根据需求可将release目录下的文件分开上传，例如lib目录下的依赖jar包没有更新就不需要每次重复校验上传了。
