.project file is missing

[GrandMasterRubix 0]

I followed the installation page on the wiki all the way to the end. I downloaded the recommended source of forge. I got Eclipse Mars. I did point the workspace to the Eclipse folder in my forge folder. Eclipse recognizes that Minecraft is the project for which I want to work on. However, when I try to open the project I get this message:

I cropped it just to show the problem I am getting.

Any and all help would be greatly appreciated.

You ran gradlew eclipse?

Actually no. I ran "gradlew setup eclipse" I'm not sure how that would be different.

Well that worked. Actually running Gradlew eclipse.
