Grails mail plugin runtime configuration

Question

Using grails mail plugin 1.0.7.

https://jira.grails.org/browse/GPMAIL-36 states that it's possible to change plguin configuration since 1.0.1 at runtime. Sadly it does not explains how to achieve it.

I want to be able to change the username at runtime to be able to use different mail accounts.

Thanks.

Based on this code, you should be able to change the configuration at runtime and the mail plugin will automagically re-deploy and update mail sender based on your changes.

Example:

Holders.config.grails.mail.username = 'foo'
Holders.config.grails.mail.password = 'bar'
sendMail {
    to "foo@bar.com"
    from "bar@foo.com"
    subject "Hi"
    body "This is an email"
} 

Update:

It would appear that changing the configuration in this manner does not, in fact, fire the onConfigChange event. Per this, you can fire the event manually. Something like this:

Holders.pluginManager.getGrailsPlugin('mail').notifyOfEvent(GrailsPlugin.EVENT_ON_CONFIG_CHANGE, Holders.config)
