The project was not built since its build path is incomplete. Cannot find the class file for org.robovm.cocoatouch.uikit.UIApplicationDelegate$Adapter. about libgdx-users HOT 7 OPEN

I'm receiving the same error. I'm sure it's something simple but I just can't 
figure out how to fix it.

Okay I found a solution. When generating the LibGDX project, you have "Generate 
ios project" checked. It shouldn't be. And if you do want to generate one, get 
the RoboVM plugin.

Ah, that makes sense. Thanks for posting!

Whew! Finally a proposed solution to my exact error.

I used the gdx-setup-ui, which generates the LibGDX projects automatically. Do 
you know if I am able to change a setting on the robovm project within Eclipse 
to effectively uncheck "generate ios project" (i.e. change the project type to 
something else- and what should that something else be?). Or, do I have to 
generate a new individual robovm project? 

Fix: getting the robovm plugin via the update site actually fixed this one for 
me. No more errors.

Thanks for your help! :)
