My apologies, that may be what I ran into. I had some SE project files in there, and when I cleaned those out, it did open the project. Not sure which way is more correct, but when I open that project in NetBeans (I was using this before SE supported groovy) it basically shows 3 gradle sub-projects within, where SE just shows one project with all the source included-though the job-dsl-api-viewer seems to be missing?
I'm very new to gradle and groovy, so it was very helpful to me the way NetBeans handled this, but I still move around 10 times faster in SE, so even basic support is an improvement to my productivity. It's good to work in my preferred editor, so thanks for all your help!
