Subversion plugin in eclipse has some issues for doing a svn cleanup of the folder. So, i thought of going to the terminal and running a svn cleanup but unfortunately that too doesn't work. I am getting the following error, looks like i need to upgrade svn client to 1.6
 
svn: This client is too old to work with working copy '.'.  You need to get a newer Subversion client, or to downgrade this working copy.See http://subversion.tigris.org/faq.html#working-copy-format-change for details.
 

I am using eclipse galileo 3.5 with the following plugins

Subversive SVN Team Provider 0.7.8
Subversive connector SVNKit 1.3.0 from http://www.polarion.org/projects/subversive/download/eclipse/2.0/update-site/

I checked out the files from the svn server and it worked great. But now i have added a folder and a file to the project and when tried to commit the changes i am getting the following error. I am stuck now without being checking in the files. If anyone faced this before please help.
