减少jar包大小

背景：微服务架构，每个jar包都有100多M，传包速度又很慢，有点折磨

pom文件引入以下配置

 <build>
       <!-- 打出的jar包包名  -->
        <finalName>${project.artifactId}</finalName>
        <plugins>
            <plugin>

                    <layout>ZIP</layout>
                    <!-- 配置需要打包进项目的jar包 -->
                    <includes>
                        <!-- 需要排除所有依赖 配置non-exists这个就行 -->
                         <!--<include> -->

jar包启动脚本如下

#!/bin/bash

#MetaspaceSize:元空间默认大小
#MaxMetaspaceSize:元空间最大大小
#JVM参数

#杀死已有进程
