3.1.5 Compatibility

[helgew]

The plugin does not work under grails 3.1.5 . After recompilation and declaring a runtime dependency on 'org.grails:grails-datastore-rest-client:5.0.0.RC2', the following error is produced when trying to send a message:

Commenting out line 33 in SlackService.groovy solved the issue.

Hi @helgew, I have to confess that I didn't test this plugin so much in Grails 3.x since I'm still using 2.x for my projects. I'll have a look at the bug and try to publish a new version soon.

@helgew there seems to be a problem when converting a grails.converters.JSON, so I passed a good old String and fixed it. Please try version 3.0.1 and let me know if you run into any other issues.

Thank you!
