As we have a huge SVN repository, a selective svn checkout is done to minimize the checkout and update times during the build.

First set all subfolders to be excluded:
svn co http://reposerver/repos/project/trunk source --depth immediates
svn update --set-depth exclude source\Folder1
svn update --set-depth exclude source\Folder2
svn update --set-depth exclude source\Folder3

Then the needed subfolders are included again:
svn update --set-depth infinity source\Folder2

The expected behavior is to update only the included folder on an "svn up".

The SVN plugin does not allow to update without --depth attribute. Because of this it is not possible to update depending on the workspace settings (which are mixed: immediates and infinity) but only on the possible settings in the SVN plugin (which are: infinity, empty, files, immediates)
