Added Android library project and now eclipse can't find my R class

Question

I am trying to add an 'Android Library project' I have created to another regular Android project.

The Library Project had a jar dependency and was also dependent on another java project in my workspace. I had to add both of these to the my 'regular Android project' because otherwise Eclipse could not find them (Not sure if this was the right thing to do because it would mean that I will have to manually update all projects when the library gets another jar dependency).

Anyway, the errors went away and now the Regular Android Project can't find the R class, I have tried a clean but it did not work. I checked in the /gen folder and both the R classes are there - from the library and the regular project.They have the correct strings inside them.

what is going wrong?

It happens from time to time. I usually delete the Gen folder and hit Run as....

I get a msg saying: R deleted. Recreating! and everything goes back to normal.
