springboot maven-assembly-plugin使用

官网：Apache Maven Assembly Plugin – Introduction

maven assembly plugin

The Assembly Plugin for Maven enables developers to combine project output into a single 
distributable archive that also contains dependencies, modules, site documentation, and 
other files.
# assembly插件可将project output、dependencies、模块、site文档等文件整合为一个文档

支持的文档格式

Currently it can create distributions in the following formats:
zip、tar、jar、dir、war
tar.gz (or tgz)
tar.bz2 (or tbz2)
tar.snappy
tar.xz (or txz)
and any other format that the ArchiveManager has been configured for

assembly descriptor format：描述归档文件的项目结构

示例

配置文件、依赖jar包外置，将配置文件、依赖jar包、项目jar包归档压缩
