I have an Appengine connected android project (eclipse). I am trying to deploy it as I have done countless times. But this time I am getting the following error.

So I open my osx terminal and navigate to the folder of my project. When I type

```
appcfg.py rollback .

```

I get a terminal error that

Thanks for any direction.

**Update**

I think I finally found out where it is but now I am getting permission denied when I do

```
/Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.9.3/appengine-java-sdk-1.9.3/bin/appcfg.sh rollback war

```
