# Script to compile and install calimero server + tool on an Orange Pi PC
# armbian based systems or Raspberry Pi rasbian systems
#  - installs a JDK
#  - installs Maven
# 
# Michael Albert info@michlstechblog.info
# 09.04.2018
# 
#
# Currently state is experimental
# Script should also run on x86/x64 devices 
#
# License: Feel free to modify. Feedback (positive or negative) is welcome
#
# Changes:
# 20180525-120000: Workaround for calimero-core => Master requires Java 9
# 20180518-120000: symlink /opt/calimero-server/calimero-core-2.4-rc2.jar -> /opt/calimero-server/calimero-core-2.4-SNAPSHOT.jar
# 20180603-230000: calimero-device switched to 2.4/release branch
#                  copy jar with wildcards
#                  delete all calimero-core-2.4-*test*.jar from server path
# 20180625-053000: Checkout release/2.4 from calimero-rxtx and calimero-tools
# 20180629-053500: changed copy calimero-tools-2.4-*.jar instead of SNAPSHOT
# 20180702-054500: Removed detach server process from console patch and instead added new --no-stdin command line option to systemd service file. Set default KNX Address to a valid coupler address
# 20180706-054000: knxtools script adjusted to calimero-tools-2.4-rc2.jar
# 20190925-121000: Oracle Java -> OpenJDK
# 20200110-054500: Orange PI PC: Script adjusted for Armbian with Mainline Kernel 5.4.x
