stop-app command fails in grails 3.1.0.M2

[ejaz-ahmed]

I get following results when I run stop-app command.

grails> run-app
| Running application...
Grails application running at http://localhost:8080 in environment: development
grails> stop-app
| Error Command [stop-app] error: null (Use --stacktrace to see the full trace)
grails> 
grails> stop-app
| Error Command [stop-app] error: null (Use --stacktrace to see the full trace)
grails> 

Here is the stacktrace

grails> stop-app --stacktrace
| Error Command [stop-app] error: null (NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

After investigations, this issue does not appear if I create app in non-interactive grails console like this:
grails create-app bookshop31 --profile=web-api

However if I create app using interactive console, this issue appears. Launch grails first in some directory the use create-app bookshop31 --profile=web-api.

This works for me in master and I believe is fixed by af75288
