“mfp push” throws NullPointerException while deploying adapter (MobileFirst Platform 7.1)

Question

using MobileFirst Platform CLI version 7.1.0.00.20151227-1730 I have suddenly the following error when trying to push an update I made to an adapter:

    Preparing for push...
Verifying Server Configuration...
Runtime 'localMFP' will be used to push the project into.
[Error:

Error: Sorry an error has occurred. Please check the stack above for details.

I have tried to cleanup the project, remove what was already deployed, revert my changes to what I had when I succeeded to deploy, re-install mfp cli, but I still have the issue.

Any hint on what I could do to get rid of the exception?

Thanks!

I am doing a local push, so the version is same as CLI: 7.1.0.00.20151227-1730 — Etienne N

The failure is coming from the upgrader code path, as if something is missing in the adapter files.

My suggestion is to create a new adapter and see that it gets deployed. Then, start adding back code. Maybe you will find the failing part.
