I've been using IDEA 7 and 8 for grails work without any issues; I upgraded to 9.0.1 a couple of months ago but other than just running it a couple of times I have done nothing until just now. And seeing that 9.0.2 was available I thought it best to upgrade before I resume the grails work in earnest.
But...I see everywhere: "Cannot assign 'Closure' to Object ..."
I can see that this is caused by a setting of the code Inspection parameters - but it's an odd setting for groovy/grails, isn't it ? After all, closures are used everywhere!
I have turned it off now but am obviously a little concerned that the default had it turned on - is it new in 9.0.2 ? (when I installed it just unherited the settings from the previous installation)
