Not able to view Resource folder in Bpel Project

I had created BPEL project in soa 12c. After some days, I noticed my project is not showing Resources folder.
After spending so much time, i found below solution:-

1. Go to Project .jpr file
2. Right click and edit it in notepad
3. Remove the below highlighted code from .jpr file

       4. Save the file. You will be able to see the resource folder.
