# Regardless of arch being required (amd64 or arm64) this will
# 'compile' the hawtio-online javascript package natively without
# resorting to a foreign image that would have to be emulated and
# so really sloooow!
# The resulting javascript/assets are then copied into the final image
# that conforms with the correct architecture.
