Hi, Yn,
There are eclipse plugins like Subclipse and Subversive that teach Eclipse to ignore the .svn subdirectories - I did use them successfully for several years. Additionally, the build directory should always be marked "svn:ignored", it is not good style to check temporary directories into the version repository. And with SVN 1.7, the SVN developers are actually going to change the working copy format to one central .svn directory in the working copy root - although with a different internal format than the one you suggested.

Mai 2011 05:24 An: users@subversion.apache.org Betreff: Advice:.svn directory should never put in every folder in project 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/
