# repo2docker clones the Elyra repository before the Docker image is built
# and uses the cloned directory as "root". The git extension recognizes that
# the directory is git-enabled and therefore prevents the user from 
# cloning other repositories using the UI. Remove the git artifacts in the
# root directory to work around this issue.
