eclipse RCP product - custom config.ini

My eclipse RCP (3.7) application is currently in a good shape, in which product can be exported successfully for multiple platforms and runs just fine. What I need is to change some properties in config.ini file, in particular osgi.instance.area.default and osgi.configuration.area .

In the configuration tab of eclipse product editor, I check Use an existing config.ini file and select the config.ini I created inside the same project hosting the product (and the core feature) definition.

To create the custom config.ini, I just took the one generated in a previous export, and added above properties.

What happens is that after exporting the product, config.ini is still auto-generated in configuration/config.ini , without my edits. What am I missing?

This is how my product definition looks like:

<?xml version="1.0" encoding="UTF-8"?>

<?pde version="3.5"?>



<product name="MyApp" id="it.myapp.product" application="it.myapp.application" version="1.0.0.qualifier" useFeatures="true" includeLaunchers="true">



   <configIni use="default">

      <linux>/it.myapp.app/config.ini</linux>

      <macosx>/it.myapp.app.app/config.ini</macosx>

      <solaris>/it.myapp.app.app/config.ini</solaris>

      <win32>/it.myapp.app/config.ini</win32>

   </configIni>
