steps to reproduce:

1. ASSERT: make sure that you have a folder "jboss-eap-quickstarts" in your default Eclipse git clone destination (if you didnt change your preferences, it will point to ~/git/. If you dont have it yet git clone it from https://github.com/jboss-developer/jboss-eap-quickstarts.git)
2. EXEC: create a new application using the "eap64-basic-s2i" template
3. ASSERT: the OpenShift resources for your application are created, the import wizard pops up with the following error that complains about the directory already existing:
   
4. EXEC: manually remove the directory (ex. in cmd-line)
5. EXEC: uncheck "Use default clone destination:"

Result:
The error wont go away, the wizard is still complaining even though the folder isnt in the way any more.

Hitting "Browse" and pointing to the same folder, that doesnt containt the folder anymore, wont help. The error persists. There'
s no way to work around this, you have to cancel the import and start over again.
