Obfuscate in build.xml

Question

Hi,
does obfuscating jars in ant in windows not work? I have the following code & get the error that seems to be related to obfuscation.

can anyone help with this please?

Answer 1

I ran into this same problem when using ProGuard 4.1 for Java obfuscation. The problem is that there is a space in the path to your JDK/JRE, for example: c:\Program Files\Java\jdk1.6.0_03. Because there is a space before the word "Files", it isn't working. The solution to to wrap quotes around that particular command-line argument. In ANT, I needed to use single-quotes (because double-quotes were already in use for the XML attribute) such as:
<java jar="proguard.jar" fork="true" timeout="30000">
<arg value="-libraryjars"/>
<arg value="'${java.home}/lib/rt.jar'"/> <!-- Notice both double and single quotes used on this line. -->
...rest of the arguments go here...
</java>
Alternatively, using ProGuard's custom ANT Task, it would look something like (notice the use of double-quotes around the rt.jar location):
<proguard>
-libraryjars "${java.home}/lib/rt.jar"
...rest of the arguments go here...
</proguard>
Anyways, I hope this helps you or anyone else who runs into the same problem. Both of these approaches have worked for me.
