本文详细介绍了如何使用Maven Assembly插件进行项目打包，包括配置依赖项、使用system scope引入第三方jar包以及创建assembly.xml文件的具体步骤。通过实例展示了如何打包包含所有依赖的jar文件，适用于需要独立运行的应用程序。

1.常用assembly插件的pom配置

<!-- 打包依赖 -->
<plugin>
	<artifactId>maven-assembly-plugin</artifactId>
	<configuration>
		<appendAssemblyId>false</appendAssemblyId>
		<descriptorRefs>
			<descriptorRef>jar-with-dependencies</descriptorRef>
		</descriptorRefs>
		<archive>
                        <manifest>
                            <mainClass>exec.ImportSiteToRedis</mainClass>
                        </manifest>
                </archive>
	</configuration>
	<executions>
		<execution>
			<id>make-assembly</id>
			<phase>package</phase>
			<goals>
				<goal>assembly</goal>
			</goals>
		</execution>
	</executions>
</plugin>

2.将scope=system打入依赖

第三方依赖jar包以scope=system的方式引入

<dependency>
	<groupId>com.bonc</groupId>
	<artifactId>xdrDecode</artifactId>
	<version>1.0</version>
	<scope>system</scope> 
	<systemPath>${project.basedir}/lib/xdrDecode.jar</systemPath>
</dependency>

添加assembly.xml，与pom.xml同级

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