This kind of stuff is the reason i hate programming. I don’t have a problem with logic errors, syntax errors, etc. but Christ’s dusty nuts I hate bureaucracy.

I started with a completely new set up. Wrote a hello world program. It worked fine. Then I tried to use Date(): cannot resolve class. Tried GregorianC…cannot resolve class. Everything: cannot resolve class.

10 minutes into playing with Eclipse and I am searching for obscure error.

The way it worked for me was to include all .h files that the red underline refer to, compile it clean, and then remove them. Seems that Eclipse has problem to automatically find the path but once does it holds into it.

Thanks a million for the “project – clean” suggestion. I had the same problem and this solution worked for me. Good times

I have had this problem for a long time with Eclipse Helios. Usually doing a Project Clean and then a project Refresh clears it up. Not today. I do most builds with Ant and that seems to mess it up. I agree it is a bug and a very annoying one.

This tiresome bug haunted me for abot TWO hours!!!!!
Luckily Closing project, Open Project, Project–>Clean did the trick!!

I had a similar problem; the difference was that I use ant in the command line to build, not enclipse (so build automatically is disabled).

As for others, suddenly it started showing “-cannot-be-resolved-to-a-type” errors.

After being stuck for hours; I tried the following (not sure why I did):

select an error in the “problems” tab and delete it. It worked.

So I selected all of them and simply deleted them.

Who would have thought!

(Btw its Eclipse’s unreliability the reason that I build everything from the command line)

Hello,
I did an uncheck auto build and David Resnick comment and then did a clean all. It worked!
Many thanks

I tried all the options stated above nothing worked…One of my friends faced same issue and she suggested to remove all the jar files and add again and then refresh and build…This solved my issue…
