Before committing code to the Subversion repository we always set the svn:ignore property on the directory to prevent some files and directories to be checked in. You would usually want to exclude the IDE project files and the target/ directory.
It's useful to put all the ignored files and directories into a file: .svnignore. Your .svnignore could look like:
Put the .svnignore file in the project folder and commit it to your repository so the ignored files are shared between committers.
Now reference the file with the -F option:
$ svn propset svn:ignore -F .svnignore.
Of course I hope everyone has by now moved to git and uses .gitignore for this same purpose.
