Error instantiated artefact class ... of type [class org.grails.core.DefaultGrailsServiceClass]

[Vahid Hedayati]

Hi All 

Wondering if anyone can help 

Linux grails 3.0.1 (Tried grails 3.0.2 too)

On 2nd machine, identical issue.

Unsure what is going wrong:

~/workspace-grails3/testg3-rssh$ cat ../remotessh/grails-app/services/grails/plugin/remotessh/RemotesshService.groovy 

package grails.plugin.remotessh.util

class RemotesshService {

}

~/workspace-grails3/testg3-rssh$ mv ../remotessh/grails-app/services/grails/plugin/remotessh/RemotesshService.groovy ~/

~/Documents/workspace-grails3/testg3-rssh$ grails run-app

Grails application running at http://localhost:8080

Presto all works fine, now if I move that service back in (currently blank) did have content, I get this stack trace:

Before anyone points/spots out - the package util was previous test before doing this post, even with it change to correct package

package grails.plugin.remotessh

it is still the same issue.

so did a lot of playing around found as an abstract service the issue went away but I think as an abstract class it was no longer an injectable service.

Anyhow took bit by bit apart, finally ended up creating a new plugin a new test app and putting bit by bit back in. Still unsure what the cause/issue was since it seems to be back to what it was since it is now working.
