maven打包依赖第三方包，但不打进jar包中

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.test.m2</groupId><artifactId>me-demo</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>me-demo</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.1.36</version></dependency></dependencies><build>  <pluginManagement><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-jar-plugin</artifactId><version>2.4</version><configuration><archive><!-- 不打包依赖的jar,把依赖的jar copy到lib目录，和生成的jar放在同一级目录下 --><manifest> <addClasspath>true</addClasspath><classpathPrefix>lib/</classpathPrefix><mainClass>com.test.m2.me_demo.TestMain</mainClass></manifest></archive></configuration></plugin></plugins></pluginManagement></build></project>

此时，会在MANIFEST.MF生成classpath: lib/，需要我们自己向lib添加jar

如果依赖的jar过多手动复制过于麻烦，

可以使用mvn命令：

mvn dependency:copy-dependencies -DoutputDirectory=C:\Users\lwn\Desktop\tt\lib  -DincludeScope=runtime  

命令要切换到项目的根目录里去执行，

-DoutputDirectory 指定为lib目录，可以根据实际情况指定。
