Fixing the "unable to export SWC oem" error in Flash Builder

If you created a project using Flex Builder 3 and wish to upgrade it to Flash Builder 4, you might see the following error in the Eclipse "Problems" view when you attempt to compile for the first time:

unable to export SWC oem.

I read on several sites how to fix the problem but here is my little piece of details with step-by-step instructions:

1. Shutdown eclipse
2. Using your favorite text editor, open the .flexLibProperties file in the root of your project
3. Erase all lines between the <includeResources> tags and just replace with an empty version of that tag (e.x.: <includeResources/>)
4. Save updated .flexLibProperties file
5. Start eclipse
6. Use the clean and build options under the "Project" menu
   

And voila, your project now compiles under Flash Builder 4

Enjoy!
