Grails 3 - change default port for run-app

Question

In Grails3 grails -Dserver.port=9001 run-app doesn\'t appear to work:

I\'m \"getting address already bound 8080\".

Answer 1

grails run-app --port=8081

Or in interactive mode:

run-app --port=8081

Don't forget to use the same port when you want to stop the server:

stop-app --port=8081

I believe this feature was broken in 3.0.3 and earlier versions but it definitely works in 3.0.4.
