The repository paths can be relative and absolute (starting from "/"). Absolute paths are resolved from the SVN repository root, absolute relative paths are resolved form from the VCS root.
When creating a label, the sources residing under "TrunkOrBranchRepositoryPath" will be put into the "tagDirectoryRepositoryPath/tagName" directory, where tagName is the name of the label as defined by the labeling pattern of the build configuration.
If no sources match the "TrunkOrBranchRepositoryPath", then no label will be created.
The path "tagDirectoryRepositoryPath" should already exist in the repository.
If "tagDirectoryRepositoryPath" directory already contains subdirectory with the current label name, the labeling process will fail, and the old tag directory won't be deleted or affected.
