org.eclipse.jgit.treewalk.TreeWalk.addTree()
Add an already existing tree object for walking.
The position of this tree is returned to the caller, in case the caller has lost track of the order they added the trees into the walker.
The tree must have the same root as existing trees in the walk. @param id identity of the tree object the caller wants walked. @return position of this tree within the walker. @throws MissingObjectException the given tree object does not exist in this repository. @throws IncorrectObjectTypeException the given object id does not denote a tree, but instead names some other non-tree type of object. Note that commits are not trees, even if they are sometimes called a "tree-ish". @throws CorruptObjectException the object claimed to be a tree, but its contents did not appear to be a tree. The repository may have data corruption. @throws IOException a loose object or pack file could not be read.
