"grails test-app" notification with bash and OSX

.grails-config

# OSX+bash notifications for "grails test-app"
# ---
# Pops up an OSX notification with "PASS/FAIL" whenever a "grails test-app" command finishes.

# Limitations
# ---
# Only shows notification if "grails test-app" created a new /target/test-reports/html/all.html
# Uses bash history, so it might not work if you have a shell alias for "grails test-app"
# Only works for one grails repository at a time. 
#   If you have two repositories simultaneously running "grails test-app", it won't work.
# Prepends to PROMPT_COMMAND which may not be compatible with more advanced setups.

# Future plans
# ---
# Detect early build failures, so a notification is popped up when all.html isn't regenerated


# create /tmp/grails-notify/all.html to serve as a timestamp since last `grails test-app`
# Note - only works for one repo. To make this approach compatible with multiple cloned projects, this file must be unique per clone
grails-notify-test-timestamp() {
	mkdir -p /tmp/grails-notify && touch /tmp/grails-notify/all.html
}

grails-notify() {
