On the Branches Mapping tab, view, and if required, adjust the rules to map Subversion directories (such as the trunk, branches, tags, and shelves) to Git references.
Use the following mapping format:
<Subversion-Path-Pattern>:<Git-Reference-Pattern>
Paths to Subversion directories are defined relative to the URL specified in the URL field on the Connection tab.
Adjust the default mapping rules to make them correspond to your Subversion project layout or in case you want to map only particular Subversion directories, but not all of them.
The default mapping rules:
trunk = trunk:refs/heads/master branches = branches/*:refs/heads/* tags = tags/*:refs/tags/* shelves = shelves/*:refs/shelves/*
