Compile Error Error generating final archive java.io.FileNotFoundException bin\resources.ap_ does not exist

I got the following error while building my android application in eclipse .

Compile Error: Error generating final archive: java.io.FileNotFoundException: ..\bin\resources.ap_ does not exist


It turned out that this is a common issue and different people have suggested different solutions.
I tried clean , rebuild, creating project again etc. etc. with no success

The solution which worked for me was related to metadata .
I had to delete .metadata in the eclipse's workspace. After that build was successful .
