# OBP-API Build and Run Script (HTTP4S Server)
#
# This script builds the OBP-API project and runs the HTTP4S server.
# It replaces the obsolete flushall_build_and_run.sh which referenced
# the removed obp-http4s-runner module and Jetty server.
#
# Usage:
#   ./build_and_run.sh              - Build and run with Redis flush
#   ./build_and_run.sh --no-flush   - Build and run without Redis flush
#   ./build_and_run.sh --background - Run server in background
#
# The HTTP4S server runs on the port configured in your props file
# (default: 8080 for dev.port, or 8086 for hostname port)
