Maven之如何用assembly插件打jar包

　　maven-assembly-plugin有什么好处呢？

　　英文原文：The Assembly Plugin for Maven is primarily intended to allow users to aggregate the project output along with its dependencies, 

　　                  modules, site documentation, and other files into a single distributable archive.

　　中文翻译：Assembly 插件的主要作用是，允许用户将项目输出与它的依赖项、模块、站点文档、和其他文件一起组装成一个可分发的归档文件。

　　本文以dtsf模块为例

　　

　　先看这个package.xml文件

　　

<assembly
        xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
    <id>reader-mysql</id>
    <formats>
        <format>dir</format>//打出来的是一个文件夹
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>

    <dependencySets>

        <dependencySet>
            <useProjectArtifact>true</useProjectArtifact>
            <outputDirectory>/</outputDirectory>
            <includes>
                <include>com.suning.dtsf:dtsf-worker-reader-replformysql</include>
            </includes>
        </dependencySet>

        <dependencySet>
            <useProjectArtifact>false</useProjectArtifact>
            <outputDirectory>/lib</outputDirectory>
            <scope>runtime</scope>
            <useTransitiveFiltering>true</useTransitiveFiltering>
            <excludes>
                <exclude>com.suning.dtsf:dtsf-worker-api</exclude>
                <exclude>fastjson*</exclude>
                <exclude>lz4*</exclude>
                <exclude>slf4j*</exclude>
                <exclude>log4j</exclude>
                <exclude>connect-api*</exclude>
                <exclude>kafka-clients*</exclude>
                <exclude>commons-logging*</exclude>
                <exclude>simpleclient*</exclude>
            </excludes>
        </dependencySet>
    </dependencySets>
</assembly>

　　再看 真的pom文件
