Updating SVN property "svn:needs-lock"

I want to update SVN property "svn:needs-lock开发者_C百科" on all files in a directory structure inside repository using svn command in Sun Solaris.

If I set it at trunk files, then while creating branch will it be carried to branch file ? I have tried the below command and it gave me an error.

   svn propset -R svn:needs-lock yes http://<server>/BRANCH/001_SGPB/DIR

ERROR

svn: Setting property on non-local target http:///BRANCH/001_SGPB/DIR' needs a base revision

I guess you need to specify --revprop since you are running this command against the repository and not the working copy. See this
