Griffon eclipse support plugin

Recently I was playing  with griffon which I used together with jung library to visualize binary decision diagrams. In this regard, I had to make several small projects. Since I do that in my spare time, at the moment I start a new project I forgot how I managed to integrate previous griffon project with eclipse IDE (actually I am using Spring Tool Suite with Groovy and Grails support but I guess it’s the same as with eclipse) so that IDE doesn’t pop up nasty message similar to:

The project was not built since its build path is incomplete.
Cannot find the class file for groovy.lang.GroovyObject.
Fix the build path then try building this project.
The type groovy.lang.GroovyObject cannot be resolved.
It is indirectly referenced from required .class files 
Config.groovy    /myprojectname/griffon-app/conf    line 1

I used: griffon integrate-with -eclipse command which actually allowed me to import griffon project to eclipse but that wasn’t enough.

The solution was eclipse support plugin.

Having that written down I hope I won’t forget it again. 🙂
