The project cannot be built until build path errors are resolved

I have set up a new Mac (Yosemite) and installed Eclipse IDE for Android (Luna). ADT is up to date. Eclipse is up to date.

I have pulled down my projects from a common git repo and created the projects in the workspace automatically. However in the problems tab, the projects all have the same error:

The project cannot be built until build path errors are resolved - Unknown - Java Problem

There are no errors in the Java Build Path properties window.

I have cleaned all projects. I have restarted Eclipse and still the errors remain. The post that may be a duplicate may work for some, I have tried all remedies posted there without fixing the issue.

How do I resolve these?

Thought I had resolved this with a clean rebuild of the repo/projects, but I was wrong.

I've found I sometimes have to change the classpath, then change it back to address this problem. – T.D. Smith Sep 17 '15 at 19:12
@mvd Not a dupe - that does not resolve the issue, as I state in my post - cleaning does not resolve. – Roy Hinkley Sep 17 '15 at 19:13
Those are the only errors in your Problems view? Are you sure you checked all of the tabs in the Java Build Path window (Source, Projects, Libraries, etc.)? – Evan LaHurd Sep 17 '15 at 19:28
@EvanLaHurd Yes, currently those are the only 3 errors. – Roy Hinkley Sep 17 '15 at 19:29
Are there any warnings? Anything useful in the console window? – ventsyv Sep 17 '15 at 19:33
Hm, usually there's a missing source folder or required project/library. You said you did try a clean, but are you sure it rebuilt, too? – Evan LaHurd Sep 17 '15 at 19:33
@EvanLaHurd It's not building, but I am not sure why. Java Build Path looks clean (no missing references). Something very strange going on though. – Roy Hinkley Sep 17 '15 at 19:38
To me this looks like a JDK error. Check Eclipse->Preferences->Installed JREs and make sure it's pointing to the correct place. – ventsyv Sep 17 '15 at 19:41
Also right click on the project - > Properties -> Project Facets and make sure that eclipse knows what type of project it's dealing with. – ventsyv Sep 17 '15 at 19:58
@ventsyv - I don't have a `project facets` option as you describe the path to. – Roy Hinkley Sep 17 '15 at 20:00
That might be missing from ADT. Did you verify that you JRE is set up correctly? – ventsyv Sep 17 '15 at 20:09
@ventsyv - Yes please see my updated post. – Roy Hinkley Sep 17 '15 at 20:11
