Android : Eclipse - can't export project as mobile application (Apache Cordova)

I've configured my Eclipse by installing Jboss Luna and Apache Cordova plugins ( Cordova Simulator etc. ). I have also installed Android Studio to have possibility for running application on Android Device or Android Emulator. When I'm trying to export my application as Mobile Application it occurs an error:

    Buildfile: D:\Projekty Java\eclipse-jee-luna-SR2-win32-x86_64\eclipse\configuration\org.eclipse.osgi\1049\data\proj_gen\zespolowy-ratchet\android\build.xml

I have no idea why it's happening. Can you help me guys ? Cheers
