proguard in eclipse java proyect

[david luis]

Hi,
I would like to obfuscate my java project but I can't
I download proguard and I copy in my project the jar file. I do:

java -jar proguard.jar @para.pro -verbose

but doesnt works, it says me that dont find the file.
I see in my workspace that the file of the project is .project

27/02/2014  10:42    <DIR>          .
27/02/2014  10:42    <DIR>          ..
05/02/2014  12:19               329 .classpath
27/02/2014  10:39               380 .project
27/02/2014  10:47    <DIR>          bin
24/02/2014  11:23           772.617 proguard.jar
24/02/2014  16:24    <DIR>          src
               3 archivos        773.326 bytes

Could you help me please?
Many thanks and sorry for my English!

Doesn't find which file ? Copy and paste the exact error message.

D:\workspace\para>java -jar proguard.jar @para.pro -verbose
Error: para.pro (El sistema no puede encontrar el archivo especificado)

@ is a shorthand form of the -include option, which allows you to specify a file in which more configuration options can be found.
So you are telling proguard to use the configuration options specified in the file para.pro. That's the file it can't find, because as you can see from your directory listing, it doesn't exist.

Yes, but I dont have any .pro file. I'm working with eclipse.

So don't use that option.
If there's no para.pro file, there's no point in telling proguard to get options from it.
