maven-assembly-plugin

1. 定制化打包插件
2. 项目中往往有很多shell脚本、SQL脚本、.properties及.xml配置项等，采用assembly插件可以让输出的结构清晰而标准化。
3. 配合着shell启动脚本往往可以达到秒启动的效果，尤其在依赖其他项目或native包的服务部署更为明显，大大的加快了部署效率

如何使用

要使用该插件，就在项目pom文件中的build>plugins配置中加入以下内容。

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-assembly-plugin</artifactId>
	<configuration>
		<descriptors>
			<!-- 指定assembly xml文件 -->
			<descriptor>src/assembly/distribution.xml</descriptor>
		</descriptors>
	</configuration>
	<executions>
		<execution>
			<!-- 名称 -->
			<id>make-assembly</id>
			<!-- 绑定到package生命周期 -->
			<phase>package</phase>
			<goals>
				<!-- 标识只运行一次 -->
				<goal>single</goal>
			</goals>
		</execution>
	</executions>
</plugin>

src/assembly/distribution.xml文件描述如下

<assembly

此时使用maven打包，就可以得到一个tar.gz的构建产物，配合着启动脚本使用更加强大 maven package
