maven之打依赖jar包

最近在写java，由于之前一直写python，对java知之甚少，也不用maven，今天用maven打jar包，各种坎坷，有打不进去依赖的，有maven报ERROR的，网上的资料零零碎碎，黏贴进pom文件各种报错，下面总结一下我正确的打依赖jar包方式，pom文件如下：

<?xml version="1.0" encoding="UTF-8"?>

运行package之后，会生成两个jar文件，一个xxxx.jar, 另一个是xxxx.one-jar.jar, 其中xxxx.jar是不含依赖的jar包，xxxx.one-jar.jar是含依赖的jar包， 直接运行含依赖的jar包就行（PS：注意修改其中的<mainClass></mainClass>标签中的内容）
