I recently relesead a new 0.2.0 version of Grails equals hashCode plugin.

There two mayor changed:

• the package of EqualsHashCodeSpec changed from es.osoco to es.osoco.grails.plugins according to Osoco‘s convention (update your imports after upgrading)
• modified and ignored property values can be evaluated lazily. You find an example in the user guide

Hope you find the plugin useful!
