Android : Can't build or run cordova app on osx

When I try to build an phonegap/cordova app with command:

cordova build android

I'm getting an error:

BUILD FAILED
Target "debug" does not exist in the project "CordovaApp". 

Total time: 0 seconds

/path_to_app/platforms/android/cordova/node_modules/q/q.js:126

You may n

ot have the required environment or OS to build this project

I think it can be related with my ~/Library/Android/sdk/tools/ant/build.xml file - I maybe accidentally mess it up - could anyone provide me code from that file?

Please help.
