For some reason, after going through Phonegap\'s non-inclusive instructions (it doesn\'t even mention setting up ANT, or the headaches with Ant and JDK), this doesn\'t work
Run cordova -d build. If it says anything about "Unable to locate tools.jar", fix that. Then completely rebuild the application by running cordova platform rm android. Also remove the project from eclispe. Then recreate the app by running cordova platform add android + cordova build. Finally add the project in eclipse again.
org.apache.cordova should now be included and everything should be working.
