Trouble setting up development environment

All,
I followed the documentation listed under the “How to set up a development environment for openHAB” section but when I get the IDE set up I get a list of errors involving missing types:

I’m getting a lot of these errors and they seem to have to do mostly with the test packages. Is there something I need to include in my project or modify to get rid of these errors? I’m also getting them on the ui package which is causing the PaperUI to function incorrectly.

Pointers are appreciated.

Thanks!
Matt

Anyone run into any issues like this that I could get some tips? I figure I’m just missing something on my system.

Thanks!
