SVN obstructed key word meaning

if you find obstructed keyword against any directory when you check for modifications of your current working directory.
Follow the following steps to resolve this issue.
(let's assume the directory name is codeRepo)
1) Rename the directory (codeRepo to codeRepo_bkup)
2) Cleanup the entire svn folder.
3) Now do the svn update, the folder get added to your code (means codeRepo folder is added again)
4) Now copy all the files from backup directory (codeRepo_bkup) and paste them in current svn directory (codeRepo), so that you will not miss any changes that you made.
5) And now you can delete the backup file (remove codeRepo_bkup)

The root cause of this is adding or removing a current svn directory from any other sources(like eclipse etc) other than from folder.
