Proguard return an error when I try to use it in Eclipse

Question

I am trying to export an Android application using ProGuard but when I do it I receive this error of the console:

[2014-04-18 16:04:37 - YesMa] Proguard returned with error code 1. See console
[2014-04-18 16:04:37 - YesMa] java.io.FileNotFoundException: Android\YesMa\proguard\dump.txt (El sistema no puede encontrar la ruta especificada)

In my project I have:

project.properties

# Many comments
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-19
android.library.reference.1=../appcompat_v7
android.library.reference.2=../gridlayout_v7

proguard-project.txt

# Many comments

Here "SDK-PATH...\tools\proguard\bin\" I have written this in the three files:

SET PROGUARD_HOME="C:\Users\Alberto\Desktop\adt-bundle-windows-x86_64-20131030\sdk\tools\proguard"

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

I don't understand the error, I have seen many post but I haven't found the solution. How could I fix it?

Answer 1

I have solved the problem putting the names of all folders of my workspace path without spaces. For example: "A - X" --> "A-X"
