I solve this problem with cleaning project. Right-click on Project name -> Clean.

This is happening because it's trying to add two files with the same name to the archive. Check the XML of your project file for the duplicate. As an aside, it's likely that your project is actually displaying a file twice in the explorer and you've dismissed it as a anomaly or bug, so that might be a hint as to which file is the problem.
