Multiple configuration files for the ProGuard Ant task

Question

I am using the ProGuard ant task, and everything is great, except that my ProGuard configuration file is huge. Also, different tasks use different ProGuard configuration files, and there is a lot of copy-pasting that I would like to refactor into separate .pro files.

<taskdef resource="proguard/ant/task.properties" classpath="C:/Program Files/proguard4.7/lib/proguard.jar"/>
<target name="obfuscated_jar" depends="raw_jar">
    <proguard configuration="core.pro lib1.pro lib2.pro">
        <outjar path="prog_obfuscated.jar"/>
    </proguard>
</target>

The above doesn't work, because it treats the multiple .pro files as one big filename. I'm a known idiot w.r.t. ant, am I missing something obvious? Thanks!

Answer 1

You can create a single main .pro file that contains -include options pointing to your actual .pro files.
