解决：Error: Unable to access jarfile ..\lib\proguard.jar

今天无意升级了ADT到ADT 22.6，打包混淆的时候就出现了问题：

Proguard returned with error code 1. See console

Error: Unable to access jarfile ..\lib\proguard.jar

一直找不到问题的解决方案，后来我把proguard（下载地址：http://sourceforge.net/projects/proguard/files/proguard/）也升级到最新版还是不行。

后来我仔细看了一下报错信息，我觉的是路径的问题,我就试着将

D:\android-sdk-windows\tools\proguard\bin\proguard.bat 打开内容如下：

@ECHO OFF

REM Start-up script for ProGuard -- free class file shrinker, optimizer,

REM obfuscator, and preverifier for Java bytecode.

REM

REM Note: when passing file names containing spaces to this script,

REM       you'll have to add escaped quotes around them, e.g.

REM       "\"C:/My Directory/My File.txt\""

IF EXIST "%PROGUARD_HOME%" GOTO home

SET PROGUARD_HOME=..

:home

java -jar "%PROGUARD_HOME%\lib\proguard.jar" %*

我试着改了一下

@ECHO OFF

REM Start-up script for ProGuard -- free class file shrinker, optimizer,

REM obfuscator, and preverifier for Java bytecode.

REM

REM Note: when passing file names containing spaces to this script,

REM       you'll have to add escaped quotes around them, e.g.

IF EXIST "%PROGUARD_HOME%" GOTO home

SET PROGUARD_HOME="D:\android-sdk-windows\tools\proguard"

:home

java -jar "%PROGUARD_HOME%\lib\proguard.jar" %*

再次进行打包混淆，没有出现异常
