Grails 4: Standalone port

I'm using Grails 4.x and create a runnable war via

grails war

command. I can run it via

java -jar myapp.jar

I would like to change the port dynamically via parameter, and tried

-Dgrails.server.port.http=8083

but with no success. It still runs on default port 8080. Earlier with Grails 2.3.6, it worked with parameter port=808.

I cannot find anything in the documentation (http://docs.grails.org/3.1.1/ref/Command%20Line/war.html)

Solution

  • If you assign a value to the server.port system property, that value will be used.
