title: Releasing patched Eclipse product
body: <p>I'm working on custom Eclipse/CDT based IDE. Up until now this was just a product based on Eclipse/CDT with custom plug-ins. I export this as product and update site and this works well enough.</p>
  
  <p>But now I need to make a small change to one of CDT plug-ins. For this I imported (only) that plug-in in question from eclipse repository and modified it. Now, with this plug-in loaded in my workspace, this version seems to take precedence over baseline, but the baseline feature containing this plug-in still requires hard-coded version of this plug-in. If I add hard-coded version number to my copy of this plug-in and then I can export product. Exported version contains the change and it works fine. But this is obviously wrong thing to do (as patched plug-in now poses for original one). I guess I can import more of CDT into my workspace and export all that, and it would work without modifying version numbers.
  Downside is that users probably can-not use default eclipse update site to install anything, as they could overwrite patched version of plug-ins with later release of unpatched ones?</p>
  
  <p>I have read obvious blog-posts on feature patches (a feature lacking documentation I must say :) ). I added feature patch for this feature and then my modified plug-in to list of required plug-ins of this feature patch.
  I can export patch feature (with plug-in version at default something.qualifier in plug-in and to "copy from plug-in and fragment manifests" in feature patch plug-ins). </p>
  
  <p>However I'am still unable to export my product. When I try to do export, it still wants original version of plug-in, which it now can not find.</p>
  
  <p>So, the questions that bugs me the most: What is the right way to release Eclipse product with minor change to one of "base" plug-ins and still allow users to use generic Eclipse (eclipse.org) update sites (to install different products, for example)?</p>
  
  <p>Or at least what is the best way to release a product with modified base plug-in?</p>
