Unable to install Grails Asynchronous Mail plugin - grails

Question

Grails Version: 3.0.9
Groovy Version: 2.4.5
JVM Version: 1.8.0_60
I'm following the simple instructions to install the Grails Asynchronous Mail plugin but I'm getting the following error message on start up.
http://grails.org/plugins.html#plugin/asynchronous-mail
Can't seem to find a solution to this no matter how much I google and trawl the web.
I'd be very grateful for any insight.

There isn't a hibernate plugin for Grails 3.x.x. You have to use hibernate3, hibernate4 or hibernate5. I've just tested with hibernate4. Also in my applications there is grails-core dependency.
compile "org.grails.plugins:hibernate4"
instead of
compile "org.grails.plugins:hibernate"
