In Grails 2, the proxy is configured and set in a file that (I believe) is in your ~/.grails directory. There are command-line arguments for setting that documented in the grails documentation here: https://grails.github.io/grails2-doc/2.4.2/ref/Command%20Line/add-proxy.html

In general you would do something like

grails add-proxy client --host=proxy-server --port=4300 --username=guest --password=guest

And then activate it like

grails set-proxy client
