maven打包依赖第三方包，但不打进jar包中

							<!-- 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>

	</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。
