Before pushing the code to GIT it is necessary to pull the code.
Now when we pull, jRebell, does accommodate the new variables added in the last commits, so it starts giving exception when we run application.
So the desirable steps would be
1. Commit your changes
2. Pull the code.
3. Refresh the eclipse work space.
4. Restart the server.
5. Unit test you changes.
6. Push the code.
