A Grails run-app Error

Question

When I typed the command grails run-app into my terminal, I got this error message:

Error Server failed to start for port 8080: Address already in use (Use --stacktrace to see the full trace)

How do I get my application to launch?

Answer 1

That would indicate you already have something running on port 8080. If you want to run your application on another port you can use the following command:

grails run-app -Dserver.port=8090

The above will run your application on port 8090.
