Possible solution

(or  Solution that worked in my case)

-Undeploy the application.

-Go to Admin server's upload folder

eg. upload in my case

cd /u01/app/oracle/product/Middleware_1034/user_projects/domains/dev/servers/AdminServer/upload

-Remove any relate archives or directories
eg. ApplicationGreeceDEV.ear or ApplicationGreeceDEV directory
from upload folder
