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"

<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。
