We have an existing project created in a version previous to Galileo. When attempting to export a EAR file from the project using either Helios or Indigo I trigger the following error:

Let me state again this works perfectly in Galileo, we are attempting to upgrade our Eclipse IDE to Indigo. We are also unable to reproduce this error when creating a new project. I have also checked the permissions and they are correct. What could be causing this?

Reproducible: Always

Steps to Reproduce:
1. Not reproducible with any other project.
2. Settings are the same.
