First, Grails/Griffon application options are available when you create a project or a module:
You may also choose to import an application from existing sources:
Earlier, you needed Gant & Gradle in module dependencies to run build scripts — quite awkward, because the way you are building your project should not affect its classpath. Now, we have per-project settings for Gant & Gradle:
Also, you can now write Groovy code and get full coding assistance with compilation as long as you have Groovy jars anywhere in a module classpath. Together with the new compiler Resource patterns path constraints feature (/ - path separator; /**/ - any number of directories) this made Groovy facet obsolete. So, there is no Groovy facet anymore.
