Advice:.svn directory should never put in every folder in project
Because:a .svn directory would break the structure of the project file. in
Eclipse, when you build the project, build direcotry would been removed.
This will cause 'obstructed' problem.
Solution: Put only one .svn directory in project home folder. and this
directry contains all other subdirectory as same as the project
Project home /
/folderA
/folderB
.....
-->
home /
/.svn/
/.svn/folderA
/.svn/folderB
/folderA
/folderB
Instead of
home /
/.svn/
/folderA
/folderA/.svn/
/folderB
/folderB/.svn/
