#    sh build.sh  --fe --be --clean         clean and build Frontend, Spark Dpp application and Backend, without web UI
#    sh build.sh  --spark-dpp               build Spark DPP application alone
#    sh build.sh  --fe --ui                 build Frontend web ui with npm
#    sh build.sh  --fe --be --ui --clean    clean and build Frontend, Spark Dpp application, Backend and web UI
#
# You need to make sure all thirdparty libraries have been
