classes.dex does not exist

Question

On running Android app FileNotFoundException is thrown and it says that classes.dex file does not exist(in the Problems tab in eclipse).

*Error:*
> Description   Resource    Path    Location    Type Error generating final
> archive: java.io.FileNotFoundException: D:\B040\Dec
> 31\AirTest\bin\classes.dex does not
> exist AirTestActivity     Unknown Android Packaging Problem

I have been stuck up on this since the last 2 days. The package explorer does not give any error(red cross on project). All other projects work fine. Only this imported project - Airpush sample is not running. The same code works fine on a different system. Need help in this.

did that. didn't work. Its not going upto the logcat stage. its not starting at all. "Your project contains error(s). Please fix them before running"- this is the alert I am getting when I try to run. — devLearner, Dec 31 '12 at 20:07
[Read this maybe](http://stackoverflow.com/questions/2865577/android-eclipse-error-android-packaging-problem) . Or create a new project copy over the java files and you get a fresh start — Erik, Dec 31 '12 at 21:04
@Ahmad: There are no errors in the build path .. I am completely lost.. — devLearner, Dec 31 '12 at 21:07
@Erik: Tried almost everything mentioned there- right from cleaning to opening the project in a new eclipse. Problem still persists. Anyways thanks. Let me know if you have something else in mind. — devLearner, Dec 31 '12 at 21:11
Go into Eclipse Preferences and on the first page you see "restore default" ...dunno — Erik, Dec 31 '12 at 21:22
Create a complete new workspace copy over the java files to a new project in the fresh workspace, happy new year :) — Erik, Dec 31 '12 at 21:28

When I ran into this problem, I did as the previous poster has suggested by deleting bin, doing a "ant clean", then "ant debug" to build a debug version using the command line. And by looking at the output I saw that my problem is that I did not have my path setup properly under MS Windows so that java.exe is not found:

-dex:

Modifying path then solved the problem for me.
