# the bucklets repo, and most plugins don't build outside the
# Gerrit tree, even with bucklets.  As a result, we need to
# graft the plugin onto the Gerrit repo.  We do this by checking
# out the proper version of Gerrit, removing the plugin if it
# exists, then use git read-tree to put the plugin we're
# building in place.
