# Infra has set up a webhook at the github repo that fires this task.
# We cannot push to github, though, but only to gitbox.
# So we need two repositories in two directories:
#
# master-branch (just cloning):
# git clone https://github.com/apache/incubator-tuweni-website.git master-branch
# asf-site-branch (pushing):
# git clone https://gitbox.apache.org/repos/asf/incubator-tuweni-website.git asf-site-branch
TEMPDIR="$(mktemp  -d -t tuweni-site-XXXXXXX)"

git clone https://gitbox.apache.org/repos/asf/incubator-tuweni-website.git asf-site-branch
