A common cause for this is if you have more than one file referencing the same object. The extra details on the error may well indicate which object is the cause.
Did you manually amend any of the files in your source control repository? Such as making a copy of some of the files for backup purposes?

Another potential is if you have objects named the same apart from their case (upper/lower etc) and you're not using a case sensitive collation.

Hope that helps - contact us directly at support if you get stuck!
