#
# Usage:
#
#     bpatch [user@]hostname [norestart]
#
#  [user@]hostname  : the hostname of the bubble node to update. Optionally, also specify a username.
#                     Usually you will have an entry in ~/.ssh/config to set the username and ssh key
#  norestart        : If present, do not restart the API server after updating the jar file
#
# Patch the bubble.jar on a remote node.
# This script only works if the only classes that have changed are in the bubble-server codebase.
# If other classes have changed, use bpatchfull
#
# You install the JDK on the remote node first: apt install openjdk-11-jdk-headless
#
# Environment variables:
#
#  BUBBLE_SSH_PORT  : SSH port, default is 1202
