有时候我们的项目依赖的jar包比较多，项目会很大，那我们每次部署更新的时候上传都会很慢，其实我们只是想更新里面的代码而已，而那众多的依赖包并不想重新上传，这时候我们就需要将依赖包和项目代码分离开来了
这是我分离之后target目录
其中lib下都是项目依赖的jar包，原本我的plat-admin.jar有70多M,现在只有1M多了
下面是pom.xml的plugin配置
<build>

<configuration>
<fork>true</fork>

</build>pom.xml中加上上面的配置那么打包出来的项目代码和依赖的jar包就会分离开来了
linux运行项目的jar包就不是之前的: nohup java -jar xxx.jar & 了
需要指定lib目录: nohup java -Dloader.path=lib包的路径,resources,lib -Dfile.encoding=utf-8 -jar xxx.jar &
最后再补一个启动这种jar包的shell脚本
