PS：下面看下Maven打包生成可运行bat/sh脚本文件

利用Maven的appassembler-maven-plugin插件，就可以实现自动打包可运行的脚本，还可以跨平台。

　　org.codehaus.mojo

　　appassembler-maven-plugin

1.1.1

　　flat

　　lib

　　src/main/resources/conf

conf

true

true

startup

${project.build.directory}/server

-Xms768m -Xmx768m -XX:PermSize=128m

　　-XX:MaxPermSize=256m -XX:NewSize=192m -XX:MaxNewSize=384m

　　windows

　　 unix

　　com.coderli.onecoder.server.HypervisorServer

　　　　startup

然后选择要编译的工程，右键->maven build… 命令如下图：

package appassembler:assemble

然后执行run，一个可执行的脚本文件就生成好了。startup.bat是windows下的，startup.sh是linux下的
