Create scripts for building business and running applications

As developer I'd like to have single script that allows to build and run complete business application. This would enforce the order of build in such a way:

• build model project (if exists)
• build kjar project
• build service project
• run service project (best would be to use java -jar of the build spring boot service project that will include module and kjar)

this script should be in two flavours

• linux/unix/mac
• windows
