# Note [Cleaning up after shell executor]
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# As noted in [1], gitlab-runner's shell executor doesn't clean up its working
# directory after builds. Unfortunately, we are forced to use the shell executor
# on Windows. To avoid running out of disk space we add a stage at the end of
# the build to remove the \GitLabRunner\builds directory. Since we only run a
# single build at a time on Windows this should be safe.
