问题场景
写好了一个jar包，使用了Java8的新特性，需要发布给客户，考虑到客户并不一定会使用Java8，所以就把JRE8一起发布了，分为Windows和Linux两个版本，各自写了一个脚本来运行。
脚本
Windows：
client.bat
@echo off rem The running environment of test.jar is jdk1.8 at least. if "%OS%" == "Windows_NT" setlocal rem --------------------------------------------------------------------------- rem Start script for the xxx client rem --------------------------------------------------------------------------- set "CURRENT_DIR=%cd%" set "JRE_HOME=%CURRENT_DIR%" if exist "%JRE_HOME%\jre\bin\java.exe" goto okHome cd .. set "JRE_HOME=%cd%" cd "%CURRENT_DIR%" :okHome set "EXECUTABLE=%JRE_HOME%\jre\bin\java.exe" rem Check that target executable exists if exist "%EXECUTABLE%" goto okExec echo Cannot find "%EXECUTABLE%" echo This file is needed to run this program goto end :okExec rem Get remaining unshifted command line arguments and save them in the set CMD_LINE_ARGS= :setArgs if ""%1""=="""" goto doneSetArgs set CMD_LINE_ARGS=%CMD_LINE_ARGS% %1 shift goto setArgs :doneSetArgs cd jre\bin java -jar %JRE_HOME%\test.jar %CMD_LINE_ARGS% :end
Linux:
client.sh
#!/usr/bin/env bash # This is a shell for running test. var="test" dir=`pwd` if [ ${var} = ${dir##*/} ]; then ./jre/bin/java -jar ${dir}/test.jar "$@" else echo "U should enter in directory ${var}, and type ./start.sh parameterlist" fi
注意
jre/bin目录需要替换成自己本地jre目录文件夹名称
test.jar需要修改成自己工程的jar包名称
