7、assembly打包命令
学习目标：
1、使用assembly打包项目
学习过程：
使用maven打包时，maven-jar-plugin插件会在target目录下生成可执行的xxx-0.0.1-SNAPSHOT.jar文件，但是一般生产程序部署时需要打包自定义的格式包，这种情况就可以使用maven-assembly-plugin插件。
一、新建相关的目录和文件。
其中bin下面的运行命令文件也是需要我们直接编写的，具体大家可以下载源码看一下。
二、打包配置

</assembly>三、修改pom.xml
我们可以绑定package命令。也可以直接使用assembly:assembly时才使用打包命令
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptor>src/main/assembly/assembly.xml</descriptor>
</configuration>
<!-- 使用assembly:assembly -->
<!-- <executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions> -->
</plugin>运行打包命令后回生产一个压缩包
里面是我们定义的标准格式，以后我们可以直接使用bin下面的命令就可以运行了。压缩包是我们的标准目录结构
完整的pom.xml如下：
