Proguard Error: Unknown option '(' in argu

Question

I can't export my project with proguard, I get this error and out of solutions.. I don't know where is this argument number 12 ...

[2013-05-14 17:38:39 - LiveWallpaper] Proguard returned with error code 1. See console
[2013-05-14 17:38:39 - LiveWallpaper] Error: Unknown option '(' in argument number 12

my project.properties:

# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=proguard.cfg

# Project target.
target=android-13

and my proguard.cfg is empty.

Thanks!

Answer 1

Ok so I found the solution using Proguard ParseException with Default proguard.cfg on Android

My problem was the my workplace directory folder name was with a "(" character .. so I moved it to another directory without whitespaces or "(" and it solved it.
